actionlayer-mcp

MCP server for ActionLayer — give Claude Code (and any MCP host) access to ActionLayer's typed action catalog: 30+ actions across Gmail, Calendar, Drive, Slack, Notion, GitHub, Stripe, Linear, Resy, Partiful, USPS, and more.

Install

claude mcp add --scope user actionlayer "uvx" "actionlayer-mcp" \
  --env ACTIONLAYER_API_KEY="ak_…" \
  --env ACTIONLAYER_API_URL="https://api.action-layer.dev"

Summarize my 3 most recent unread emails.

How it works

This package is a thin shim. The actual execution lives on ActionLayer's service. The MCP server here exposes one tool — actionlayer_invoke_action — plus helpers to list the catalog, create jobs, and manage the cyborg loop. Auth is via your bearer API key; the server proxies calls and surfaces the typed response back to your agent host.

Usage from other MCP hosts

# stdio transport (default)
actionlayer-mcp

# also works with Cursor, Cody, Codex, etc. — any MCP host

Env vars:

• ACTIONLAYER_API_KEY — required, your bearer key
• ACTIONLAYER_API_URL — defaults to https://api.action-layer.dev

Changelog

0.2.0

• Async-by-default dispatch for browser actions. actionlayer_invoke_action now returns outcome="queued" + payload.ticket_id for browser actions instead of holding the connection open for minutes (the previous behavior hit gateway timeouts at 60s and triggered LLM retries that double-fired browser sessions).
• New actionlayer_get_action_ticket(ticket_id) MCP tool — poll an action ticket until terminal. Returns is_terminal, outcome, output, live_view_url, etc.
• Updated actionlayer_invoke_action docstring with explicit "DO NOT RETRY when outcome==queued" instructions for agent hosts.

0.1.0

• Initial release. Six MCP tools: list_actions, get_action, invoke_action, create_job, get_job, cancel_job + legacy ticket tools.
