Use this catalog inside Claude, Grok and ChatGPT

LesFM is an MCP server: plug it into your AI assistant and it can search every original track while you chat.

MCP (Model Context Protocol) is the standard that lets AI assistants use external tools. Add the URL below to Claude, Grok, ChatGPT, Cursor or any MCP client, and when you ask for piano, cinematic, lo-fi or a mood it can pull real tracks — titles, BPM, duration and page links — instead of guessing.

MCP access
