Threads MCP Server & CLI

Threads MCP server and CLI for Claude Code, Codex and AI agents. 30 tools for posting, chained threads, carousels, replies and reply approvals, insights, keyword search and profile discovery.

One install gives you both surfaces, the same tools under the same names, covering everything the app does and several things it cannot.

Threads has its own API, separate from Instagram's, so it needs its own token. One Meta app can carry both, with one app id and one testers list.

Publishing and deleting ask for confirmation. Everything else is a read.

One command to authorise, and the 60-day token refreshes itself from then on.

Built and maintained by Navid Moazzez. Built on Slipway, which turns one definition of each tool into the MCP server and the CLI.

Two ways to use it

Command line

threads-cli in your terminal, for scripting, cron, pipes, or a quick question without opening anything:

threads-cli                                       # every command, one line each
threads-cli whoami                                # which profile the token belongs to
threads-cli get-publishing-limit                  # how much quota is left today
threads-cli get-posts --limit 10                  # your recent posts
threads-cli get-top-posts --limit 25              # ranked by engagement against views
threads-cli search-keyword "model context protocol"
threads-cli create-post --text "Shipped." --confirm
threads-cli list-accounts --json | jq -r '.accounts[].username'
threads-cli <command> --help                      # what any command takes

--confirm is the shell spelling of the confirmation that posting, replying and deleting require. --json gives JSON, --compact puts it on one line, --agent turns on all of the machine-readable defaults at once, and errors are JSON on stderr whichever you pick.

threads-cli schema <command> prints the exact JSON Schema an MCP client receives for that tool, which is how you can check the two surfaces really are one thing.

Output and exit codes

Every command exits with a number a script can branch on, so nothing has to parse the message:

| Code | Means | |---|---| | 0 | It worked | | 1 | An unexpected error, worth an issue | | 2 | You typed it wrong, or the guard refused a write: a missing or bad flag, an unknown command, a command hidden by THREADS_READ_ONLY=1, a post without --confirm, Meta rejecting the arguments | | 3 | Not found | | 4 | The token was rejected, or lacks the permission | | 5 | The Threads API failed or could not be reached | | 7 | Rate limited, back off and retry | | 10 | Nothing is configured yet, run threads-cli login |

threads-cli create-post --text "$BODY" --confirm --agent > /tmp/out.json
case $? in
  0) ;;
  2|4) echo "fix the command or the token, not retrying" >&2; exit 1 ;;
  7) echo "rate limited, backing off" >&2 ;;
  10) echo "no profile connected, run threads-cli login" >&2; exit 1 ;;
  5) echo "Threads failed, will retry" >&2 ;;
  *) echo "unexpected, see the error" >&2; exit 1 ;;
esac

MCP server, for your AI app

threads-mcp is what Claude Code, Claude Desktop, Cursor and the rest launch. You never run it by hand:

claude mcp add threads -- npx -y @thenavidm/threads-mcp-cli

No credentials go in that line, because threads-cli login already stored the token. Then just ask: "which of my posts this month actually worked, ranked by engagement against views?"

Every other client is in section 2. Each post, reply, repost and delete waits for your approval in the client, as section 6 explains.

Which one

| Where you are | What you can reach | |---|---| | An agent that can run shell commands, like Claude Code or Cursor | Both. The CLI is the cheaper one: it costs nothing until you type it | | claude.ai, the Claude Desktop chat tab, or a phone | The server only. There is no shell to run a command in | | A terminal, a script, cron or CI | The CLI only. There is no MCP client in a shell |

They are the same program reading the same tool definitions, so anything one can do, the other can.

Features

Every tool is both a command and an MCP tool, with the same name. The command is the tool name with dashes.

| Capability | CLI command | MCP tool | |---|---|---| | Which profile, and the daily quota | threads-cli whoami / get-publishing-limit | whoami / get_publishing_limit | | List connected profiles | threads-cli list-accounts | list_accounts | | Post, thread or carousel | threads-cli create-post / create-thread / create-carousel | create_post / create_thread / create_carousel | | Stage a post, publish it later | threads-cli stage-post / publish-staged / get-container-status | stage_post / publish_staged / get_container_status | | Quote and repost | threads-cli quote-post / repost | quote_post / repost | | Delete one of your posts | threads-cli delete-post | delete_post | | Reply, and read replies | threads-cli reply-to / get-replies / get-conversation / get-all-replies | reply_to / get_replies / get_conversation / get_all_replies | | Hide a reply, or work the approval queue | threads-cli hide-reply / get-pending-replies / manage-pending-reply | hide_reply / get_pending_replies / manage_pending_reply | | Read your posts | threads-cli get-posts / get-post | get_posts / get_post | | Insights and what worked | threads-cli get-post-insights / get-account-insights / get-top-posts | get_post_insights / get_account_insights / get_top_posts | | Who follows you | threads-cli get-follower-demographics | get_follower_demographics | | Search posts and topic tags | threads-cli search-keyword / search-topic-tag | search_keyword / search_topic_tag | | Look up a public profile | threads-cli lookup-profile | lookup_profile | | Geo-gating countries | threads-cli list-allowlisted-countries | list_allowlisted_countries | | Keep the token alive | threads-cli refresh-token, or threads-cli refresh for every stored one | refresh_token | | Check your setup | threads-cli doctor | not a tool |

All 30 with their arguments are in section 5.

1. What you can ask it

• Post this, and put the link in a card rather than as bare text.
• Turn these notes into a thread. Show me the draft first, then stage part one so I can see it before anything is public.
• Which of my posts this month actually worked, ranked by engagement against views rather than raw likes?
• Read every reply I got today and tell me which ones deserve an answer.
• Publish these six screenshots as a carousel with alt text on each.
• Hide that reply, and everything nested under it.
• How much of today's posting quota have I used?
• Where are my followers, by country?
• Search for what people are saying about this launch, ranked by engagement.
• Restrict this post to the UK and Sweden.

The third one is the point. Threads reports views alongside likes, replies, reposts and quotes, so engagement can be measured against reach instead of against nothing. Ranked by raw likes, your best post is usually just your oldest.

2. Install

The long version, every step with what to do when one fails, is in INSTALL.md.

Node 22 or newer. Nothing else.

Authorise first, in a terminal:

export THREADS_APP_ID=...        # from your Meta app
export THREADS_APP_SECRET=...
npx -y @thenavidm/threads-mcp-cli login

That stores a 60-day token at ~/.threads-mcp/tokens.json, and every client below picks it up with no credentials in its config at all. Section 3 covers where the app id and secret come from.

Claude Code

claude mcp add threads -- npx -y @thenavidm/threads-mcp-cli

A terminal

npm install -g @thenavidm/threads-mcp-cli
threads-cli

threads-cli install claude-code (or codex, claude-desktop, cursor, vscode, gemini) adds the server to a client in its own format; add --dry-run to see the change first.

That gives you two commands: threads-mcp is the server your AI tools launch, and threads-cli is the one you type. Both are the same program.

Claude Desktop

The quickest route is the extension: download the .mcpb from the latest release and double-click it. No config file to edit. Leave its token field empty and it picks up the refreshable one login wrote.

To wire it up by hand instead:

1. Open the config file.

In Claude Desktop, go to Settings, then Developer, then click Edit Config. That reveals claude_desktop_config.json in your file manager. Open it in any text editor.

If you would rather go straight there:

| System | Config file | |---|---| | macOS | ~/Library/Application Support/Claude/claude_desktop_config.json | | Windows | %APPDATA%\Claude\claude_desktop_config.json | | Linux | ~/.config/Claude/claude_desktop_config.json |

On macOS you can open it from a terminal with:

open -e ~/Library/Application\ Support/Claude/claude_desktop_config.json

2. Add the server.

If the file is empty or does not exist, paste this whole thing in:

{
  "mcpServers": {
    "threads": {
      "command": "npx",
      "args": ["-y", "@thenavidm/threads-mcp-cli"]
    }
  }
}

If you already have other servers, add only the "threads": { ... } part inside your existing "mcpServers", and put a comma after the entry before it. The file has to stay valid JSON. A single missing comma or a trailing one stops every server from loading, not just this one.

No credentials go in this file, because login already stored the token. If you would rather keep it here instead, add an env block with THREADS_ACCESS_TOKEN, and read section 10 first: a token in a config file cannot be refreshed by anything, so it dies on day 60.

3. Restart properly.

Quit Claude Desktop completely and reopen it. On macOS closing the window is not enough, use Cmd+Q. On Windows quit it from the system tray. Claude only reads that file at startup.

4. Check it worked.

Look for the tools icon in the message box and click it. You should see threads with its tools listed. Then ask it something from section 1.

If nothing appears, Claude Desktop's own log is the fastest way in:

| System | Log file | |---|---| | macOS | ~/Library/Logs/Claude/mcp-server-threads.log | | Windows | %APPDATA%\Claude\logs\mcp-server-threads.log |

tail -n 50 ~/Library/Logs/Claude/mcp-server-threads.log

Two things account for most failures. Node is not installed, or not on the PATH that Claude Desktop sees, in which case use the full path to node as the command. Or the JSON is malformed, which you can check by pasting the file into any JSON validator.

Cursor

Create ~/.cursor/mcp.json for every project, or .cursor/mcp.json inside a single project. Use the same JSON as Claude Desktop. Then reload the window, or open Settings, MCP, and toggle the server.

Windsurf

~/.codeium/windsurf/mcp_config.json, same JSON, then reload.

VS Code

.vscode/mcp.json in a project, or run MCP: Add Server from the command palette.

Everything else

Zed, Cline, Continue and anything else that speaks MCP over stdio all work. They each keep their config somewhere different, but they all want the same things: the command, the args, and optionally the env.

Docker

The token store has to be mounted, or the container authorises into a filesystem that disappears:

docker build -t threads-mcp .
docker run --rm -i \
  -v ~/.threads-mcp:/home/node/.threads-mcp \
  threads-mcp

Self-hosting over HTTP

For a machine that is always on, which is also the most reliable way to keep a token alive:

THREADS_HTTP_PORT=8787 \
THREADS_HTTP_TOKEN=$(openssl rand -hex 32) \
threads-mcp --http

Binds 127.0.0.1 by default, and will not start on any other address without THREADS_HTTP_TOKEN. A Threads token can post as you, so put it behind a reverse proxy with TLS before you change THREADS_HTTP_HOST. GET /health returns the name, version and tool count without authentication.

Check it worked

npx -y @thenavidm/threads-mcp-cli doctor

It checks the network, then each token, then probes every capability separately: publishing, replies, insights, keyword search, profile discovery, geo-gating. Each one reports granted, missing, or missing with the exact scope to add.

3. Connect your account

Threads has no app passwords. Every credential is an OAuth token minted against a Meta app you own, which is a real setup step, so here it is in full. It takes about ten minutes once.

Create the app

[!TIP] One app covers Facebook, Instagram and Threads.

Use cases are ticked in a list, and you can tick several. If you plan to use more than one of these, do it now rather than making three apps and managing three sets of credentials.

| Use case | For | Server | |---|---|---| | Manage everything on your Page | Facebook Pages | facebook-mcp | | Manage messaging and content on Instagram | Instagram | instagram-mcp | | Access Threads API | Threads | this one |

Incompatible combinations grey out. If an option will not tick, it conflicts with something already selected.

1. Go to developers.facebook.com/apps and Create App.

2. Choose the Threads API use case.

3. In the app, open Threads API, then Settings. Copy the Threads App ID and Threads App Secret.

4. Under Redirect Callback URLs, add:

   http://127.0.0.1:8788/callback

   That is the loopback address login listens on. It never leaves your machine. If port 8788 is taken, use login --port=9000 and add the matching URL instead.

5. Under Roles, add yourself as a Threads Tester, then accept the invitation from your Threads profile at Settings, Website permissions, Invites.

Step 5 is the one people miss. Without it, every call comes back empty and nothing explains why.

Authorise

export THREADS_APP_ID=1234567890
export THREADS_APP_SECRET=abc123...
threads-mcp login

That opens the authorisation page, catches the redirect, exchanges the code, exchanges the short-lived token for a 60-day one, verifies it against your profile, and writes it to ~/.threads-mcp/tokens.json at mode 0600.

For the permissions that need App Review, once you have them:

threads-mcp login --all-scopes

If the browser cannot open, threads-mcp login --manual prints the URL and takes a pasted token instead.

The scopes

login requests these by default, and they work for you as a tester on your own app with no review at all:

| Scope | What it unlocks | |---|---| | threads_basic | Everything. Required for any call | | threads_content_publish | Posting, threads, carousels, quotes, reposts | | threads_manage_replies | Hiding replies, reply approvals | | threads_read_replies | Reading replies and conversations | | threads_manage_insights | Post and profile metrics, follower demographics | | threads_delete | Deleting your own posts |

These three need App Review, and --all-scopes requests them:

| Scope | What it unlocks | |---|---| | threads_keyword_search | Searching posts other than your own | | threads_profile_discovery | Looking up other public profiles | | threads_location_tagging | Tagging posts with a location |

A missing scope usually shows up as an empty result rather than an error. threads_keyword_search is the worst of them: without it, Meta does not refuse a search, it quietly narrows it to your own posts. search_keyword notices when every result is yours and says so, and doctor probes for it directly.

Pasting a token instead

You can skip login and set THREADS_ACCESS_TOKEN to a long-lived token you already have. Everything works, with one consequence: the server has nowhere to write a refreshed token, so it cannot keep that one alive. See section 10.

Tokens from Meta's Graph API Explorer are short-lived and stop working in an hour. That is the single most common reason a Threads setup "randomly breaks".

4. What it costs to have connected

Both surfaces are the same program with the same 30 tools. The difference is when the model pays for them. Measured in Claude Code:

| Cost | MCP server | CLI | |---|---|---| | Every message, with every tool loaded | 11,400 tokens | nothing | | Every message, Claude Code's default | 1,060 tokens | nothing | | When Threads comes up | nothing more, or the tools it picks | 3,140 tokens for SKILL.md, once | | 20 messages with Threads in 1, every tool loaded | 227,000 tokens | 3,140 tokens |

Claude Code's tool search is on by default: it sends only the tool names and the server instructions, and loads a tool's full definition when the model reaches for it. An app that loads every tool up front pays the first line on every message, whether Threads comes up or not. With the skill added, Claude Code also lists its one-line description, about 140 tokens.

Where the tokens go, with every tool loaded:

| Part of the tool list | Share | |---|---| | JSON Schema structure: types, required lists, nesting | 56% | | Argument descriptions | 28% | | Tool descriptions | 16% |

To spend less, turn the server off when you are not using it, which in Claude Code is the /mcp panel. THREADS_READ_ONLY=1 takes the 12 write tools off the list, leaving 18. Or install the CLI and add the server on the days it earns its place.

Measured on 2026-10-05 with Claude Code 2.1.286 on Claude Opus 5.5: one short prompt with and without the server connected, once with ENABLE_TOOL_SEARCH=false and once with the default, the difference read from the API's own usage figures. SKILL.md was measured the same way, and the shares were counted with OpenAI's o200k tokenizer. Other apps and models count tokens a little differently.

Against 1.1.2, measured the same day: every tool loaded costs 11,356 tokens instead of 12,745, tool search the same, and SKILL.md 68 more for the approval rule, which and the full exit codes. In Codex 0.159.3 on gpt-6.1-sol, the same task, "find the command that publishes a post staged earlier and the flags it requires", read a median of 84,035 input tokens on 2.0.0 against 84,054 on 1.1.2 over the CLI (five runs each), and about 78,750 on both over MCP.

5. Tools

30 tools. Every one takes an optional account; every listing tool takes limit and cursor. Anywhere a post is named, it is the numeric id, which every read tool returns.

Accounts

| Tool | What it does | |---|---| | list_accounts | Every connected profile, which one acts by default, and days left on each token | | whoami | Authenticate and return the live profile. Use this to confirm credentials | | get_publishing_limit | How much of today's posting, reply and delete quota is spent | | refresh_token | Extend this profile's token by another 60 days |

Posting

| Tool | Arguments | |---|---| | create_post | text, image_url, video_url, alt_text, link_attachment, topic_tag, reply_to_id, quote_post_id, reply_control, allowlisted_country_codes, enable_reply_approvals, confirm | | create_thread | posts[], image_url, video_url, alt_text, link_attachment, topic_tag, reply_to_id, reply_control, confirm | | create_carousel | items[], text, topic_tag, reply_control, confirm | | stage_post | Everything create_post takes, minus confirm. Builds a container, publishes nothing | | publish_staged | container_id, confirm | | get_container_status | container_id | | quote_post | text, quoted_post_id, confirm | | repost | id, confirm | | delete_post | id, confirm |

Replies

| Tool | Arguments | |---|---| | reply_to | id, text, image_url, video_url, alt_text, confirm | | get_replies | id, reverse, limit, cursor | | get_conversation | id, reverse, limit, cursor | | get_all_replies | since_hours, limit, cursor | | hide_reply | reply_id, hide | | get_pending_replies | limit, cursor | | manage_pending_reply | reply_id, action, confirm |

Threads exposes three different reply views and they are not interchangeable. get_replies is one level deep under one post. get_conversation is the whole tree under one of your posts. get_all_replies is every reply you have received across every post, which is the one you want when the question is "what needs answering".

Reading

| Tool | Arguments | |---|---| | get_posts | since_hours, since, until, limit, cursor | | get_post | id |

since_hours reads a time window rather than a count: since_hours: 168 pages until it reaches a week back.

Insights

| Tool | Arguments | |---|---| | get_post_insights | id | | get_account_insights | since, until, metrics[] | | get_follower_demographics | breakdown (country, city, age, gender) | | get_top_posts | sample, sort_by |

get_top_posts is the one that does not map to an endpoint. It fetches recent posts, pulls metrics for each, and ranks by engagement against views. That costs one request per post, so the sample is capped at 50 and the result says what it scored.

Profile insights only go back to 13 April 2024, and are unreliable before 1 June 2024. Earlier windows return nothing rather than an error.

Search and discovery

| Tool | Arguments | |---|---| | search_keyword | q, search_type, media_type, since, until, limit, cursor | | search_topic_tag | tag, search_type, limit, cursor | | lookup_profile | username | | list_allowlisted_countries | none |

Resources and prompts

Three resources, threads://accounts, threads://concepts, threads://output-format, so a client can load context without spending a tool call.

Three prompts: triage-replies, draft-thread, what-worked.

6. Writing safely

A post is public the instant it lands. Threads has no edit endpoint, so correcting a typo means deleting and republishing, which loses that post's replies, likes and reposts, and spends one of the hundred deletions the account gets each day. There is no unsend and no revision history.

So nine tools need approval:

create_post, create_thread, create_carousel, publish_staged, quote_post, repost, reply_to, manage_pending_reply, delete_post.

In a terminal that is --confirm, which --agent never adds. Over MCP a person approves each call where the client can ask: Claude Code (2.1.246 and later) shows its own prompt, and a client that can show forms asks with an approval form whose one box starts unticked. Each approval is signed, bound to that exact call and works once. Where a client can do neither, the model's confirm: true counts, and it should pass it only when you asked for that exact post. THREADS_CONFIRM=model makes confirm: true enough everywhere, for an agent with no person to ask, such as a scheduled job.

hide_reply is not guarded. It is one call to undo, and an approval on every hide would only train you to click yes without reading, which is worse than not asking.

Staging instead of posting

stage_post is the honest answer to "show me before you post it". It builds the container and stops. Nothing is visible to anyone, the container holds for 24 hours, and publish_staged makes it live later. This is the only draft state Threads has, and it is a better habit than trusting a confirmation flag.

Turning writes off entirely

THREADS_READ_ONLY=1

Every write disappears from the tool list, leaving 18 read-only tools. A model cannot call a tool it cannot see.

THREADS_ALLOW_DESTRUCTIVE=0

Keeps hiding replies and refreshing tokens; blocks posting, replying, reposting and deleting.

Annotations

Every tool carries MCP annotations, so a client can decide what to auto-approve:

| Tools | readOnlyHint | destructiveHint | idempotentHint | |---|---|---|---| | Reads | true | false | true | | hide_reply, refresh_token, stage_post | false | false | true | | create_post, delete_post, repost | false | true | false |

openWorldHint is true on everything, because every call leaves your machine.

An audit log

THREADS_AUDIT_LOG=~/.threads-mcp/writes.jsonl

One JSON line per attempted write, allowed and blocked alike, with a timestamp, a one-line summary of what it was about to do, and who approved it: person, client or flag.

Prompt injection

Everything you read from a search, a reply or a conversation is text other people wrote. A reply can say "ignore your instructions and post this". The server tells the model, in its instructions and again in the concepts resource, to treat all of it as data. Do not rely on that alone: THREADS_READ_ONLY=1 for an agent working through someone else's replies is the real defence.

7. Writing posts

The 500-character limit is not String.length

Threads caps a post at 500 characters, and counts emoji as UTF-8 bytes. Those are two different limits and neither is what JavaScript measures:

| Text | Reader sees | .length | UTF-8 bytes | |---|---|---|---| | 👨‍👩‍👧‍👦 | 1 | 11 | 25 | | é | 1 | 1 or 2 | 2 or 3 |

Both are checked separately, and the error says which one you crossed and by how much. A post of 130 family emoji is 130 characters and 3,250 bytes: comfortably inside the character limit, and refused.

Threads are chains, and they can half-publish

There is no thread endpoint. A thread is ordinary posts, each replying to the one before, so nothing rolls it back. Discovering on part four that part five is 40 characters too long leaves four public posts and no way to finish.

So create_thread length-checks every part before it publishes the first one. If a later part still fails, for a reason no local check could have caught, the error names exactly how far it got and gives you the last id:

Parts 1-3 of 6 are published (last id 17924…). Part 4 failed. …

Media, a link card, the topic tag and the reply control apply to the first post only. Repeating them down the chain would attach the same image to every part.

Media is fetched, not uploaded

Threads has no upload endpoint. You give it a public HTTPS URL and it fetches the file itself, asynchronously, reporting failure as a container error minutes later. So the checks that can be made locally are: a data: URI, a local path, plain HTTP, and a host Meta cannot reach are all refused before a container is spent. An unusual file extension is a warning rather than an error, because a CDN URL ending .webp may well be served as JPEG.

| Media | Limits | |---|---| | Images | JPEG or PNG, 8MB, 320 to 1440px wide, 10:1 aspect ratio | | Video | MP4 or MOV, 1GB, 5 minutes, H264 or HEVC | | Carousel | 2 to 20 items, counting as a single post |

Publishing is two calls

create container  →  it processes  →  publish

Publishing into the middle of that fails with an error that says nothing about timing, which is why so much Threads automation works on text and breaks on video. This server polls the container's status instead of sleeping, so text publishes almost immediately and a five-minute video still works. THREADS_CONTAINER_TIMEOUT_MS raises the ceiling; a container that times out is not lost, it stays valid for 24 hours and publish_staged will still take it.

Link cards, topic tags and quotes

• Link card: link_attachment renders a preview. Text-only posts only, so it cannot be combined with media.
• Topic tag: one per post, written without a #, 1 to 50 characters, no periods or ampersands. A leading # is stripped rather than refused.
• Quote: quote_post_id, or the quote_post tool.
• Links in text: at most five distinct URLs, which is a warning rather than a refusal.

Who can reply

reply_control on create_post and create_thread:

| Value | Who can reply | |---|---| | everyone | anyone (the default) | | accounts_you_follow | only accounts you follow | | followers_only | only accounts that follow you | | mentioned_only | only accounts named in the post | | parent_post_author_only | only the author of the post being replied to |

enable_reply_approvals: true holds replies for approval instead. They stay invisible until you approve them; read the queue with get_pending_replies.

Geo-gating

allowlisted_country_codes: ["GB", "SE"] restricts a post to those countries. Meta enables this per profile and there is no way to request it through the API. whoami reports whether the profile is eligible, and list_allowlisted_countries returns what it may use.

8. Reading posts

Listings come back as tagged text rather than Graph API JSON, roughly a tenth the size, with the text where a model expects it.

<posts count="2" account="thenavidm" cursor="…">
  <post id="17924…" type="standalone" url="https://www.threads.com/@thenavidm/post/C…"
        author="thenavidm" posted_at="2026-08-31T09:14:02.000Z" topic_tag="buildinpublic">
    <content>
The post text, exactly as published.
    </content>
    <media type="image" url="https://…" alt="…" />
    <engagement>1204 views, 38 likes, 4 replies</engagement>
  </post>

  <post id="17925…" type="reply" replied_to="17924…" hidden="HIDDEN">…</post>
</posts>

• posted_at is always ISO-8601 UTC. Threads answers with a +0000 offset format, normalized here so two timestamps compare.
• type is one or more of standalone, reply, quote, repost.
• replied_to and root_post carry thread structure without reordering the list.
• A quoted or reposted post nests as <quoted_post> or <reposted_post>, rather than being flattened. A repost with no text of its own is otherwise indistinguishable from an empty post.
• hidden appears on replies you have hidden, so a gap in a conversation is visible instead of implied.
• <engagement> appears only where insights were joined on, which is get_top_posts and get_post_insights.
• cursor on the root element continues the listing.

Post text is reproduced exactly, including its own line breaks. Nothing indents inside <content>.

9. Several profiles

A personal profile and a brand profile, from one server, without restarting anything to switch between them.

Set them up

Run login once per profile, signed in as that profile each time. Both land in the same store and both are refreshed independently.

Or pass them explicitly:

export THREADS_ACCOUNTS='[
  {"access_token":"THQ...","username":"thenavidm"},
  {"access_token":"THQ...","username":"navidmedia"}
]'
export THREADS_DEFAULT_ACCOUNT=thenavidm

In an MCP client config, that goes in env as a single JSON string:

{
  "mcpServers": {
    "threads": {
      "command": "npx",
      "args": ["-y", "@thenavidm/threads-mcp-cli"],
      "env": {
        "THREADS_ACCOUNTS": "[{\"access_token\":\"THQ...\",\"username\":\"thenavidm\"},{\"access_token\":\"THQ...\",\"username\":\"navidmedia\"}]",
        "THREADS_DEFAULT_ACCOUNT": "thenavidm"
      }
    }
  }
}

username and user_id are both optional. Neither is in the token, so the server resolves them from the profile on first use and caches them.

Using them

list_accounts shows what is connected, which one acts by default, and how many days each token has left. Every tool that acts as someone takes an optional account:

create_post(text: "…", account: "navidmedia", confirm: true)

How a name is matched

In order:

1. Exact username: navidmedia
2. Numeric profile id, if you pass one
3. Prefix, when it is unambiguous

Exact beats prefix deliberately. navid is a prefix of navidmedia, so a prefix-first search would hand an unnamed post to the wrong profile whenever both are connected. If nothing matches, the call fails and lists what is connected rather than guessing.

Which profile acts by default

THREADS_DEFAULT_ACCOUNT, falling back to the first account. It accepts a comma-separated list, so you can express a preference order that survives one of them being removed:

export THREADS_DEFAULT_ACCOUNT=thenavidm,navidmedia

10. Tokens

This section is the difference between a setup that keeps working and one that dies in two months.

A Threads long-lived token is valid for 60 days. It can be refreshed for another 60 at any point after it is 24 hours old. Once it expires it is gone: there is no grace period, no recovery, and the only way back is walking the whole OAuth flow again.

So:

| Where the token lives | Can this server refresh it? | |---|---| | The store, from threads-mcp login | Yes. Automatically, and written back | | THREADS_ACCESS_TOKEN in a config file | No. Nowhere to write the new value | | THREADS_ACCOUNTS JSON | No. Same reason |

When the token is one the server owns, it refreshes on its own inside the last 20 days of its life, before the request that needed it, and again reactively if Meta says the token expired between the check and the call. THREADS_REFRESH_WINDOW_DAYS moves that window.

The catch is that an MCP server launched over stdio only exists while a client has it open. If nothing runs for 60 days, nothing refreshes. Three ways to avoid that:

• Leave the MCP client connected. Normal use refreshes it.
• Run threads-mcp refresh occasionally. A cron entry once a month is plenty.
• Run it over HTTP on a machine that is always on, which never lets the window close.

list_accounts and doctor both report days remaining, and the server warns on startup when anything is inside a week.

11. How it works

src/
  index.ts              entry: both binaries, with Node's compile cache
  app.ts                the Slipway app: tools, settings, login, refresh
  guide.ts              server instructions, resources and prompts
  config.ts             credentials, and which profile acts
  doctor.ts             setup diagnosis, one probe per capability

  auth/
    login.ts            the OAuth flow on a loopback redirect
    refresh.ts          `refresh`, extending every stored token now
    tokens.ts           exchange, refresh, and the 60-day arithmetic
    store.ts            the token file, 0600, written atomically

  api/
    client.ts           Graph calls, retry, throttle, container polling
    errors.ts           one class per failure, each naming its fix
    identity.ts         post ids, container ids, permalinks

  content/
    text.ts             graphemes, UTF-8 bytes, topic tags, escaping
    media.ts            what Threads accepts, checked before a container
    containers.ts       the publish state machine, and chained threads

  format/
    posts.ts            the tagged output format

  tools/
    kit.ts              the Slipway toolkit, and Meta's errors mapped to exit codes
    accounts.ts posts.ts replies.ts read.ts insights.ts discover.ts

Two dependencies: Slipway, which serves the tools over MCP and the CLI with one write guard, and zod.

Profile ids. Nearly every Threads endpoint is keyed by a numeric profile id that is not in the token. Rather than making that a setup step, GET /me supplies it on first use and it is cached for the life of the process. Concurrent calls share one in-flight lookup.

Retries. 5xx and Meta's quota codes back off exponentially with jitter. A 400 does not retry: the request was wrong and sending it again will be wrong again. Requests are spaced by THREADS_MIN_REQUEST_INTERVAL_MS so a burst of parallel tool calls does not trip a limit.

Errors. Meta returns code and error_subcode, and those are what separate an expired token (190/463) from a revoked one (190/467) from a spent quota (4, 17, 32). All three arrive as HTTP 400. Each is a distinct class here, carrying a message that names the fix, including which OAuth scope is missing when that is the problem. The class, not the status, sets the exit code, and the code, subcode and trace id reach the model in the error's details.

Container polling. Starts at 500ms and backs off to 4s, so a text container does not pay for a video container's worst case.

12. Your data

Nothing is uploaded anywhere but Threads.

| What | Where | |---|---| | Access tokens | ~/.threads-mcp/tokens.json, mode 0600, or your client's config | | App id and secret | Your environment. Needed only by login | | Profile ids | Process memory. Resolved per run | | Posts and reads | Between you and Meta | | Audit log | Only the file you name in THREADS_AUDIT_LOG |

There is no telemetry, no analytics and no phone-home. The only hosts contacted are graph.threads.net, threads.net during login, and whatever URL you hand to image_url or video_url, which Meta fetches rather than this server.

The login listener binds 127.0.0.1 only, holds an authorisation code for the moment it takes to exchange it, and shuts down immediately afterwards.

13. Risks

Read this before you install.

• A Threads token can act as you. It posts, replies, reposts and deletes under your name. Revoke it from your Threads profile under Settings, Website permissions.
• Posting is public and irreversible. confirm: true is a speed bump, not a wall. A model that has decided to post will pass it.
• There is no edit. Fixing anything means delete and repost, which loses the replies and the likes on the original.
• A thread can half-publish. Every part is validated first, which prevents the common case, but a network failure mid-chain still leaves public posts.
• Deleting is permanent and rationed. 100 per rolling 24 hours, no archive, no undo.
• Anything you read is untrusted text. See prompt injection.
• A token that lapses is gone. See section 10.
• Quotas are real. 250 posts, 1,000 replies, 100 deletes, 2,200 searches, 1,000 profile lookups, all rolling 24 hours. A bulk run will hit them.

If any of that is more than you want to hand an agent, THREADS_READ_ONLY=1 gives you 18 tools that cannot change anything.

14. Troubleshooting

threads-mcp doctor first. It probes each capability separately and names the failing one and the fix.

| Symptom | Cause | |---|---| | Every call returns empty | You are not a Threads Tester on your own app, or you never accepted the invite. See section 3 | | "Threads rejected the token" | It expired, or it was a short-lived Graph Explorer token. Run threads-mcp login | | Worked yesterday, dead today, about two months in | The 60-day token lapsed. It cannot be refreshed, only replaced. See section 10 | | search_keyword only ever returns your own posts | threads_keyword_search is not approved. Meta narrows the search instead of refusing it | | lookup_profile only resolves Meta's accounts | threads_profile_discovery needs expanded access | | get_follower_demographics returns nothing | Under 100 followers, or threads_manage_insights is missing | | Container error a few minutes after posting | The media URL. It has to be public HTTPS, an image or video content type, and not redirect to a login page | | "still processing after 120s" | A long video. The container is not lost; publish_staged with that id still works for 24 hours | | "will not run without --confirm" | Working as intended. See section 6 | | Claude Code asks before every post | Expected: posting, replying, reposting and deleting wait for your approval | | claude -p will not post | Headless Claude Code refuses tools that need a person. Give that agent THREADS_CONFIRM=model | | No approval form appears | The client cannot show forms, so the model's confirm: true counts, and only for a post you asked for | | A piped request gets no answer | Stdin closed before the answer. The MCP stdio binding stops a server when its input ends; keep stdin open until you read the answer, or use the CLI | | "is a Threads permalink" | Threads has no endpoint converting a permalink to an id. Use the numeric id from get_posts | | Rate limited | A rolling-24-hour quota. get_publishing_limit shows what is left |

Server not appearing at all: run the command your client runs, by hand, and read stderr.

15. FAQ ❓

An MCP server is a standard way to give an AI assistant real access to a tool, so it can act rather than guess. You install it once, your assistant gains the tools, and it works in Claude, Cursor, ChatGPT and anything else that speaks the protocol.

threads-cli is the same program as the MCP server, run as commands. AI agents that run commands, like Claude Code, Codex and OpenCode, use it on their own, and you can type the same commands in a terminal, a script or a cron job. Every tool is a command with dashes, so get_top_posts runs as threads-cli get-top-posts.

Use the MCP server in an app with no terminal, like Claude Desktop's chat. Use the CLI anywhere commands run: an agent like Claude Code, Codex or OpenCode, a script or a cron job. The MCP server's tools take up context on every message, and the CLI costs nothing until it runs.

Threads is Meta's text-first social app, tied to an Instagram account. Its API is separate from Instagram's, with its own permissions and its own token, so a token that works for Instagram does nothing here.

You need one, and it is free. Threads authorises through Meta's app system, so you tick the Threads use case when creating the app. The same app can carry Instagram as well, with one app id and one testers list, though each product issues its own token.

Your Threads profile is tied to an Instagram account, so yes in that sense. You do not need the Instagram API or its permissions to use this server.

Nothing leaves your machine except calls to Meta. There is no backend here, no account to create and no telemetry. Your token sits in your client's config.

It posts when you ask it to. Publishing, replying, reposting and deleting wait for your approval: Claude Code shows its own prompt for each one, and a client that can show forms asks with one. Where a client can do neither, the model's confirm: true counts, which is a speed bump against a careless call rather than a lock. Hiding a reply is not guarded, because it is one click to undo.

Setting THREADS_READ_ONLY=1 removes every write tool from the list, so the model cannot see or call them.

A missing OAuth scope and an App Review that has not been granted look identical from a tool call, which is why doctor exists: it probes each capability and names which scope is missing rather than leaving you to guess.

It reads your own profile and its replies. Meta's API does not expose other people's posts the way a public search would, so competitor research is not something this can do honestly.

It costs nothing. The server is MIT licensed and Meta's API is free at the volumes a person generates.

It works with any MCP client. Claude Code, Claude Desktop, Cursor, Windsurf, VS Code, Codex CLI and Gemini CLI all run it the same way.

Long-lived tokens last 60 days and can be refreshed before they lapse. doctor reports how long each one has left, so this is visible before it breaks rather than after.

Remove the app's access from your Threads or Instagram settings, which invalidates the token immediately, then remove the server from your client's config.
