Lacuna Music is a Model Context Protocol (MCP) server: Generate AI music via the Lacuna Music API from MCP clients like Claude Desktop & Code. Because it speaks the Model Context Protocol, AI assistants can use Lacuna Music as a set of callable tools instead of you copy-pasting between apps.
You can run Lacuna Music two ways: connect to the hosted endpoint at https://www.lacuna.fm/mcp with no local install, or run it on your own machine via the npm package lacuna-mcp. Configuration happens through environment variables — you'll need LACUNA_API_KEY. The current release is v0.3.4, published under the MIT license, with source at JOYLINK-LTD/lacuna-toolkit on GitHub.
On mcp.site, Lacuna Music sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
