## What it does

Audionaut connects an AI agent to open multitrack projects through MCP. The agent can cut audio, set fade-in and fade-out points, analyse a project and export the result. The project stays open in the Audionaut desktop app.

You need Audionaut and Node.js 18+ before connecting the server. On macOS, projects should be kept in the Music folder. The app is a hard requirement: without Audionaut installed and open, this server cannot edit the project.

The server is listed for Claude Code, Codex, Cursor, GitHub Copilot, Windsurf (Devin Desktop), Cline and Zed. In Claude Code, add it with `claude mcp add audionaut -- npx -y audionaut-mcp`.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `AUDIONAUT_CLI` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
