3Create 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.
