meta-mcp

Read-only MCP server for Meta (Facebook) Graph API. Plugs into Claude Code (and any other MCP-compatible client) over stdio (local) or Streamable HTTP (remote).

Covers four API surfaces with a single long-lived token:

• Marketing API — ad accounts, campaigns, ad sets, ads, creatives, insights
• Facebook Pages — pages, posts, comments, page insights
• Instagram Graph — business accounts, media, media/account insights, hashtag search
• WhatsApp Business — WABAs, phone numbers, message templates, analytics

Plus debug_token (inspect any token) and graph_get (raw GET escape-hatch).

HTTP method is hard-coded to GET everywhere — Claude cannot accidentally create, mutate, or delete anything.

Tools

Specialized (validated with zod):

| Surface | Tools | |---|---| | Common | graph_get, debug_token | | Pages | pages_list, page_get, page_posts, post_get, post_comments, page_insights | | Marketing | ad_accounts_list, ad_account_get, campaigns_list, campaign_get, adsets_list, ads_list, adcreatives_list, adcreative_get, insights | | Instagram | ig_business_account_get, ig_media_list, ig_media_get, ig_media_insights, ig_user_insights, ig_hashtag_search, ig_hashtag_media | | WhatsApp | wa_business_owned_wabas, wa_phone_numbers, wa_phone_number_get, wa_message_templates, wa_template_get, wa_analytics |

1. Get an access token

The token prefix EAA... is the same for every Graph token type — you can't tell which kind you have from the prefix. Run debug_token after first start to identify it. The four kinds:

| Kind | When to use | How to obtain | |---|---|---| | System User | Recommended for ads / business automation — long-lived, doesn't tie to a human account | Business Manager → Business settings → Users → System users → Generate new token | | Page Access Token | Single page only | Graph Explorer with a user token: GET /me/accounts?fields=access_token | | User OAuth token | Personal access, expires in ~60 days | Standard FB Login OAuth flow | | App access token | Server-to-server calls that don't need user context (e.g. debug_token) | APPID|APPSECRET literal |

For page_insights and any Instagram tool you need a Page Access Token. This server resolves it lazily: if FB_ACCESS_TOKEN is a user/system token with admin rights, calling any Page/IG tool triggers a one-time /me/accounts fetch that caches each page's token. No manual swap needed.

2. App credentials (recommended)

If you set both FB_APP_ID and FB_APP_SECRET in .env:

• Every request is signed with appsecret_proof — Meta's defence against token replay if the access token leaks.
• debug_token works (Meta requires APPID|APPSECRET to call that endpoint).

Find them at developers.facebook.com → My Apps → {your app} → Settings → Basic.

3. Three ways to run

| Mode | When to use | |---|---| | npm (npx) | Easiest for end users — no clone, no build | | stdio (from source) | Hacking on the server locally | | Docker (Ubuntu) | Shared server, multiple devices, mobile, teammates |

A. Install from npm

claude mcp add meta \
  --env FB_ACCESS_TOKEN=<your-token> \
  --env FB_APP_ID=<your-app-id> \
  --env FB_APP_SECRET=<your-app-secret> \
  -- npx -y meta-mcp

Or manually in ~/.claude.json:

{
  "mcpServers": {
    "meta": {
      "command": "npx",
      "args": ["-y", "meta-mcp"],
      "env": {
        "FB_ACCESS_TOKEN": "EAA...",
        "FB_APP_ID": "<your-app-id>",
        "FB_APP_SECRET": "<your-app-secret>"
      }
    }
  }
}

In Claude Code: /mcp → meta: connected.

B. Local — stdio from source

git clone https://github.com/nourgithub/meta-mcp.git
cd meta-mcp
cp .env.example .env
# edit .env — set FB_ACCESS_TOKEN at minimum
# (also FB_APP_ID + FB_APP_SECRET for debug_token / appsecret_proof)
npm install
npm run build
claude mcp add meta -- node "$(pwd)/dist/index.js"

C. Remote — Docker on Ubuntu

Everything ships in deploy/:

• deploy/Dockerfile — multi-stage Node 20 alpine build, runs as non-root with tini for clean signals
• deploy/docker-compose.yml — two services: the app + Caddy as TLS-terminating reverse proxy
• deploy/Caddyfile — auto-HTTPS via Let's Encrypt, proxies /mcp (SSE-aware) and /health

Pre-requisites: Ubuntu server with public IP and a DNS A-record pointing your domain at it.

# 1) On the server — install Docker
ssh root@SERVER_IP
apt-get update
apt-get install -y ca-certificates curl
install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
chmod a+r /etc/apt/keyrings/docker.asc
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu $(. /etc/os-release && echo $VERSION_CODENAME) stable" \
  > /etc/apt/sources.list.d/docker.list
apt-get update
apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# 2) Open ports 80 and 443 (skip if no ufw)
ufw allow 80/tcp
ufw allow 443/tcp

From your laptop, push the project to the server:

tar -czf - -C /d/meta-mcp \
  --exclude='./node_modules' --exclude='./dist' --exclude='./.env' --exclude='./.git' . \
  | ssh root@SERVER_IP "mkdir -p /opt/meta-mcp && tar -xzf - -C /opt/meta-mcp"

Back on the server, prepare .env:

ssh root@SERVER_IP
cd /opt/meta-mcp
cp .env.example .env
nano .env

Fill at minimum:

FB_ACCESS_TOKEN=EAA...
FB_APP_ID=...
FB_APP_SECRET=...

MCP_TRANSPORT=http
MCP_HTTP_PORT=8765
MCP_HTTP_AUTH_TOKEN=<openssl rand -hex 32>
MCP_HTTP_ALLOWED_HOSTS=meta-mcp.example.com

META_MCP_DOMAIN=meta-mcp.example.com
[email protected]

chmod 600 .env. Build and start:

cd /opt/meta-mcp/deploy
docker compose build
docker compose up -d
docker compose ps      # both services should be "running" / "healthy"
docker compose logs -f # watch Caddy fetch the cert

Verify:

curl https://meta-mcp.example.com/health
# {"ok":true,"name":"meta-mcp"}

curl -i -X POST https://meta-mcp.example.com/mcp
# 401 — missing bearer (expected)

Connect Claude Code:

claude mcp add --transport http meta https://meta-mcp.example.com/mcp \
  --header "Authorization: Bearer <your MCP_HTTP_AUTH_TOKEN>"

Pagination

All *_list tools accept:

• limit — page size (default 25)
• auto_paginate=true — walk paging.next up to max_pages (default 4) times
• max_pages — safety cap

When auto_paginate=true the response shape is:

{
  "items": [ ...flattened from all pages ],
  "pages": 3,
  "truncated": false,
  "next_cursor": "QVFIUjF..."
}

Cursors are short-lived (~30 min). Don't reuse a stale next_cursor after a long delay.

Rate limits

Meta's actual budget depends on app tier (Standard / Advanced), token type, and per-object usage — there is no single fixed RPS for Graph API. The server applies:

• Client-side: soft cap of META_RPS_LIMIT requests / second (default 25, env-tunable).
• Header-aware cooldown: after each response we parse X-App-Usage, X-Ad-Account-Usage, X-Business-Use-Case-Usage. If any bucket > 90%, the next request is delayed (using estimated_time_to_regain_access if present).
• Retry: on HTTP 429 or Graph error codes 4, 17, 32, 613 the request is retried with exponential backoff (max 2 retries).

Security

• FB_ACCESS_TOKEN is sent only as Authorization: Bearer header, never as a query parameter — keeps it out of proxy / CDN logs.
• If FB_APP_SECRET is set, every request includes appsecret_proof (HMAC-SHA256 of token with secret). Token replay from another machine fails.
• Graph error bodies are scrubbed before being returned: occurrences of the token, app secret and appsecret_proof are replaced with *** to prevent leakage via tool output.
• HTTP mode: MCP_HTTP_AUTH_TOKEN is mandatory, compared with constant-time. MCP_HTTP_ALLOWED_HOSTS enables DNS-rebinding protection.
• HTTPS in Docker mode handled by Caddy automatically.

Caveats

• Insights async jobs not supported. For huge Ads Insights ranges Meta recommends POST /insights → poll report_run_id. This server is GET-only; use shorter ranges or export from Ads Manager.
• Webhook subscriptions out of scope. MCP is a request/response model; subscribing to realtime updates needs a separate server.
• Page-token cache is per-process. Restarting the server clears it. First IG/Page-Insights call after restart triggers one extra /me/accounts round-trip.
