Hatchet tools (10, 3 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • cancel_runswrite action

    MUTATES LIVE STATE. Cancel one or more runs/tasks by external id.

  • get_queue_metrics

    Get task/queue metrics for the tenant (queue health).

  • get_runwrite action

    Get the full detail of one workflow run (status, tasks, errors) by its external id.

  • get_run_logswrite action

    Get log lines for a task by its external id.

  • list_runs

    List recent workflow/task runs. Filters: status, workflow ids, time window. Defaults to the last 24h if 'since' is omitted.

  • list_workers

    List workers and their status.

  • list_workflows

    List workflow definitions for the tenant.

  • replay_runs

    MUTATES LIVE STATE. Replay/retry one or more runs/tasks by external id.

  • trigger_workflow

    MUTATES LIVE STATE. Trigger a new workflow run by name with a JSON input payload.

  • whoami

    Show the resolved Hatchet tenant + server URL and confirm the token works.

Install Hatchet in Claude Code, Cursor or VS Code

Runs npx -y hatchet-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Hatchet repository's README, as published. We do not edit it. Read it on GitHub

hatchet-mcp

An MCP server that lets AI agents observe and operate Hatchet workflows — status, runs, logs, workers, and metrics, plus trigger / cancel / replay.

Why: Hatchet has a great API but no MCP. This wraps it so agents (Claude Code / Desktop, etc.) can see and act on workflow state.

Install

Add this to your Claude Code / Claude Desktop MCP config:

{
  "mcpServers": {
    "hatchet": {
      "command": "npx",
      "args": ["-y", "hatchet-mcp"],
      "env": { "HATCHET_CLIENT_TOKEN": "<your-hatchet-api-token>" }
    }
  }
}

Get the token from the Hatchet dashboard → API tokens. The token is a JWT that encodes the server URL and tenant, so it's the only required setting.

Configuration

Self-hosting? Set HATCHETAPIBASE to your own Hatchet instance and it works anywhere.

Tools

Observability (read-only)

Actions (mutate live state)

Safety

The read tools (whoami, listworkflows, listruns, getrun, getrunlogs, listworkers, getqueuemetrics) are non-destructive.

triggerworkflow, cancelruns, and replayruns mutate live state** — their descriptions are prefixed MUTATES LIVE STATE so agents and users know they affect real runs.

The token grants full tenant access — treat it as a secret. Never commit it to source control.

Development

pnpm install
pnpm test    # vitest
pnpm build   # tsup -> dist/index.js

TypeScript / ESM, tested with vitest.

Status

v0.1.0 — all tools verified against Hatchet Cloud; works with self-hosted instances via HATCHETAPIBASE. trigger_workflow uses the stable /workflow-runs/trigger endpoint.

Nothing above is checked by us. What we check is on the safety report.
