Lacuna MCP Server 工具

Create an AI music generation task on Lacuna. Returns immediately with a `pending` task; use `wait_for_generation` or `get_generation` to retrieve the finished tracks.

Retrieve the current state of a music generation task by id.

Poll a generation task until it reaches a terminal state (`ready` or `failed`) or the timeout elapses. Returns the final task object including audio URLs on success.

概览

What is Lacuna MCP?

Lacuna MCP is a Model Context Protocol server that integrates with the Lacuna Music API. It enables MCP-compatible clients (Claude Desktop, Claude Code, Cursor, Zed, Continue, etc.) to generate AI music as part of an agent loop.

How to use Lacuna MCP?

The server is a single npm package run over stdio. No install step is needed — your MCP client launches it via npx lacuna-mcp. Configure it by setting the LACUNA_API_KEY environment variable (required, from your profile dashboard, begins with lyr_live_). An optional LACUNA_BASE_URL can override the API base URL. Music API access requires the Pro plan or above.

Key features of Lacuna MCP

  • Create music generation tasks and get immediate pending task IDs.
  • Retrieve the current state of a generation task by its ID.
  • Poll a generation task until it completes or fails.

Use cases of Lacuna MCP

  • Generate AI music autonomously within an agent workflow.
  • Check generation status and retrieve completed tracks programmatically.
  • Integrate music creation into multi-step AI processes.

Node.js 18+ and a valid API key. The server runs over stdio and is published as an npm package.
