Cueapi

Official Model Context Protocol server for CueAPI, the open-source coordination layer for AI agent systems.

Give your MCP-enabled assistant (Claude Desktop, Cursor, Zed, or any other MCP host) the ability to schedule agent work, fetch execution history, and close the loop with evidence-backed outcome reports, all from inside a conversation.

Why

Agents don't finish in one call. They coordinate across time, tools, environments, agents, and humans. Every handoff is a place where silent failure hides. CueAPI closes each handoff with structured evidence: an external ID, a result URL, or an artifact. This MCP server gives the agent direct access to that surface, so the agent can both schedule its own follow-up work and report outcomes with proof.

Install

npm install -g @cueapi/mcp
# or use via npx (no install):
npx -y @cueapi/mcp

Configure (Claude Desktop)

Add this to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "cueapi": {
      "command": "npx",
      "args": ["-y", "@cueapi/mcp"],
      "env": {
        "CUEAPI_API_KEY": "cue_sk_..."
      }
    }
  }
}

Generate your API key at cueapi.ai. Self-hosting? Set CUEAPI_BASE_URL alongside CUEAPI_API_KEY.

Configure (Cursor / Zed / other hosts)

Any MCP host that supports stdio servers can run this. Point the host at the cueapi-mcp binary and pass CUEAPI_API_KEY in the environment.

Example conversation

You: Schedule a daily 9am job that posts a digest to my webhook.

Assistant (uses cueapi_create_cue): Created cue cue_abc123, first fire tomorrow at 9:00 UTC.

You: Show me the last five times it ran.

Assistant (uses cueapi_list_executions): ...

Changelog

• 0.1.4. Fix cueapi_pause_cue / cueapi_resume_cue to use PATCH /v1/cues/{id} with {"status": "paused" | "active"} (previously called non-existent /pause and /resume endpoints, returning a runtime 404). PR #1. This is the release that actually contains the fix; 0.1.3 was published prematurely with this note but without the merged code.
• 0.1.3. Premature publish, superseded by 0.1.4. No functional changes from 0.1.2.
• 0.1.2. Register with the Official MCP Registry.
• 0.1.0. Initial release: 8 tools for create / list / get / pause / resume / delete cues, list executions, report outcome.
