@storybloq/agkit — AgentKit management CLI + MCP

agkit is the first-party command-line interface and MCP server for the AgentKit management plane. One binary, three surfaces that share a single bundled core: the agkit CLI, an MCP server (agkit mcp serve), and a typed library.

Because the three surfaces are generated from one command registry, they cannot drift apart: the same paths, the same flags, the same required scopes, the same plan/apply confirmation ceremony, whether a human types it, an agent calls it as an MCP tool, or your own code imports it.

Install

npm install -g @storybloq/agkit

Requires Node 22 or newer.

First-touch bootstrap without a global install:

npx @storybloq/agkit init

npx is supported for first-touch only (OD-24); the primary, supported path is the global install.

60-second quickstart

Install → log in → set up a project → bind a tier to a model. The last step is a production rebinding, so it goes through a plan and a typed confirmation.

1. Install.

npm install -g @storybloq/agkit

2. Log in.

agkit login

The credential lands in your OS keychain. Confirm it took:

agkit whoami

3. Set up the project end to end.

agkit init

init asks for what it needs (a project, a label for the publishable key, optionally a provider to store an API key for), prints the whole plan of action before it does any of it, and then runs it: it creates the project, mints a publishable key, stores the provider credential you named, seeds recommended default routes, and writes the SDK config artifact into the repository. Two of those legs are server-authored plans you see and approve as they come up.

It also drops .agentkit/project.json in the repo, which pins the active project. That is why nothing below needs a --project flag.

Non-interactively — CI, an agent, a script — there is no channel to ask on, so --yes is required, and it has to carry the answers it can no longer prompt for: a project selector (--project <id> for an existing one, --project-name <name> for a new one) and a key label.

agkit init --yes --project-name <name> --key-name <label>

Be exact about what --yes buys, because the difference is your traffic. It answers the plain y/N prompts, and it never satisfies a typed confirm. init's second leg — the provider credential plus the default model routes — is prod-rebinding, so under --yes that plan is created and left OPEN, never applied: the run reports the credential and the routes as pending, prints the plan id with a runnable agkit plan show <plan-id> and agkit plan apply <plan-id> pair, and exits 3 — a partial, not a success. The project, the publishable key and the config artifact are real; your routes are not bound until you apply that plan with its typed confirm string, exactly the way step 5 does it.

4. Bind a tier to a model — as a plan, not an edit.

agkit route create --tier premium --model claude-opus-4-1 --provider anthropic --execution-target cloud_relay --attestation off --plan-only

Creating a model route is PR — prod-rebinding. It re-points live traffic, so the server authors a plan instead of mutating anything. --plan-only stops right there and emits that plan as data (exit 0); nothing has been applied yet. The plan carries its own id and, because it is PR-class, the exact confirm string you have to repeat back.

5. Apply it. Take the id and the confirm string from the plan step 4 just emitted:

agkit apply plan_UKiJIG6eQXCCi-K6cyYxsA --confirm "apply PR plan: model_route.create"

Before it applies anything, the ceremony renders the plan on stderr so you are confirming what the server actually intends to do, not what you meant to ask for:

Plan plan_UKiJIG6eQXCCi-K6cyYxsA - danger PR (prod-rebinding)
  expires in 15m 0s
  !! PROD-REBINDING: this plan re-binds LIVE traffic - model_route.create
  changes:
    create model_route /v1/management/projects/00000000-0000-4000-b000-00000000900d/model-routes
      (absent) -> {"tier":"premium","model":"claude-opus-4-1","provider":"anthropic","execution_target":"cloud_relay","fallback_execution_target":null,"attestation":"off","enabled":true,"default":false}
  to proceed, type this confirm string exactly:
    apply PR plan: model_route.create

On a terminal you can leave --confirm off and type the string when prompted. Plans expire, so a stale one is refused rather than silently re-created. --yes is not a substitute here: destructive and prod-rebinding plans always require the typed string.

Safer classes are cheaper. A read costs no ceremony at all, and an ordinary mutation takes a plain y/N that --yes answers — the typed confirm string appears only for the two classes that can break a live app.

The full command reference

The catalog is generated from the shipped registry, so it is never hand-maintained and never stale:

agkit reference
agkit reference --json

agkit reference prints the human Markdown catalog. agkit reference --json prints the machine registry — every command's path, flags, required scopes, danger class, and output schema id — which is what you want when you are scripting against the CLI or checking a flag spelling.

The same catalog ships inside this package as skill/reference.md, byte-identical to what the command prints, so an agent can read it without executing anything. The source repository is private, so there is no public docs URL to follow: the command is the link.

Authentication

Two login shapes, chosen for you

agkit login

When a browser is reachable, this runs the OAuth authorization-code flow with PKCE against a loopback redirect on your own machine — nothing but the browser ever sees the authorization code. On an SSH session, in a container, or anywhere a browser cannot be opened, it runs the OAuth device flow instead: the CLI prints a URL and a user code you enter from any other device. Force that path explicitly with:

agkit login --device

Which flow was chosen is announced on stderr before anything starts, so a headless machine never silently does something other than what you expected.

Tokens for CI and agents

Humans log in; robots get a minted, scoped, expiring token:

agkit token create --name ci-bot --scope routes:read --expires-in 30d

Both flags are structural, not decoration. --scope (repeat it once per scope) makes least privilege the only way to mint — a token cannot be born with more authority than you named. --expires-in is required in a non-interactive shell and capped, and there is no opt-out flag: every minted token has an end date.

The secret is displayed exactly once, at mint time, and is never retrievable again. Hand it to the consumer through the environment:

export AGKIT_TOKEN=REDACTED_SHOWN_ONCE

Scopes

A scope names a resource family and a verb, and the verbs form a ladder: read < write < destroy. Holding a higher verb satisfies the lower ones within the same family, and never across families — a deploy token with write on routes still cannot delete an issuer.

Those family:verb strings are the whole vocabulary --scopes (on login) and --scope (on a token mint) accept. Both are validated locally against the contract registry before anything is sent, so a scope the contract cannot name is a usage error on your machine, never a request the server has to judge.

With no --scopes, agkit login requests a fixed default set of read scopes and names that set on stderr before it starts, so a login shows exactly what it is asking for. Passing --scopes replaces that default rather than adding to it, and a --scopes value that names no scope at all is a usage error rather than a silent fall back to the default.

The default carries no write verb, so a command that writes configuration — agkit init, for one — needs a login that names the write scopes it uses.

The scope registry itself is not duplicated here, because a hand-copied catalog is a catalog that rots. Every command's required scopes are carried in the generated reference — the scopes field of each entry in agkit reference --json.

Where credentials come from

One chain, used identically by the CLI and by the local MCP server, in this order:

1. AGKIT_TOKEN — when set and non-empty it short-circuits the entire chain; no keychain access is attempted at all. This is the CI and agent path.
2. OS keychain, via @napi-rs/keyring — service agkit-cli, account = the active profile.
3. Credential helper — a configured executable whose stdout is one bare token.
4. A loud, structured failure (exit 2). There is no silent fallback to a plaintext file and no anonymous request: if no credential is available, the command stops and tells you which remedy applies.

On SSH and headless boxes the OS keychain is often missing or locked, and step 4 is what you will hit. Two honest ways through it: run agkit login --device on that machine, or mint a token elsewhere and export AGKIT_TOKEN for the session.

MCP client setup (local stdio)

An MCP client spawns the server itself — you register the command once and never run it by hand:

agkit mcp serve

Its stdout carries MCP protocol frames and nothing else; every diagnostic goes to stderr.

Claude Code

claude mcp add agkit -s user -- agkit mcp serve

-s user is deliberate: a project-scope registration would follow one repository, while this one provisions your machine.

Codex

Add to ~/.codex/config.toml:

[mcp_servers.agkit]
command = "agkit"
args = ["mcp", "serve"]

Regenerating these snippets

The two blocks above show the generic agkit form, which pastes on any machine. To emit them with the absolute path of the binary on this machine — what a client should actually register, so an nvm/fnm PATH change cannot break it — run:

agkit mcp print-config

The command writes nothing; agkit setup is what edits client configs. Machine-readable: agkit mcp print-config --json.

The server implements MCP protocol revision 2026-07-28 (the server/discover handshake) and still serves the legacy initialize handshake, negotiating down to any earlier revision a client requests.

Identity, credentials, and environment

MCP registry identity, in the first-party namespace: cloud.agkit/agkit.

The local MCP server reuses the CLI credential chain described above — the same single seeded client (agkit-cli), the same precedence order, the same keychain entry. Whatever agkit login stored is what the server presents. Two consequences follow, both intentional:

• There is no separate stdio OAuth client for MCP. Nothing to register, nothing to keep in sync, no second credential to leak.
• There is no agkit_login MCP tool. Logging in is a CLI-only action, so an MCP host can spend your authority but can never mint, move, or widen it.

The four environment variables an MCP host may set for the server: AGKIT_TOKEN, AGKIT_PROJECT, AGKIT_API_URL, AGKIT_PROFILE.
