logic-pro-mcp

Logic Pro MCP Server lets you run a local, open‑source MCP (Message Control Protocol) interface on macOS that AI agents such as Claude, Cursor, or VS Code can use to compose, mix, and inspect Logic Pro sessions. The server runs on your Mac and communicates with Logic Pro through explicit read‑back contracts, so you can see whether a requested operation succeeded, failed, or remains uncertain. It is packaged as a Homebrew tap and works with Logic Pro 12.0.1‑12.3 on macOS 14+ (or macOS 15.6+ for the newest Logic Pro version).

The tool is aimed at developers and power users who want to integrate AI‑driven workflows with a local Logic Pro environment. After installing the server via `brew install logic-pro-mcp`, you register a client (for example, Claude Code) with a scoped CLI command, then grant the client permission to control Logic Pro. The documentation emphasizes checking permissions (`LogicProMCP --check-permissions`) and running a diagnostic (`LogicProMCP doctor`) before sending commands. Once set up, you can issue operations such as creating an instrument track, importing MIDI, or reading track metadata through URLs like `logic://tracks`. Each write operation returns a contract status, Confirmed, Uncertain, or Failed, so you can verify the actual state of the project rather than assuming success from a send‑only response.

Typical usage follows a three‑step workflow: compose, mix, and deliver. In the compose phase you might send a prompt to an AI agent, have it generate MIDI, and then import that MIDI into a newly created track. The server will read back the created region if the target supports readback, allowing you to confirm the result. During mixing you can adjust parameters, again with explicit readback to ensure changes took effect. Finally, the deliver step can export audio or other assets, with the same verification model applied. The interface is not a live connection; recordings shown on the site are archived demos, and the server does not claim real‑time streaming capabilities.
