- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below

- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
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.
generate_music
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.
get_generation
Retrieve the current state of a music generation task by id.
wait_for_generation
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.
