Mix a song from Claude, Cursor, or Codex with MCP

· 2 min read · Orbit Waves

Short answer. Create a key in Orbit Waves Settings, add the /api/mcp endpoint with that key to Claude, Cursor, or Codex, then ask in plain words. The assistant changes the same project the browser shows, and every change is one undo.

MCP, the Model Context Protocol, lets an AI assistant use a tool the way you would use a button. Orbit Waves speaks MCP, so Claude, Cursor, Codex, or any other MCP client can open your song, split it, set the loudness, add an EQ, and save a master.

Connect in a minute

  • Open Settings in Orbit Waves and create a key. It is shown once.
  • Add the endpoint: this site plus /api/mcp, with the header Authorization: Bearer and your key.
  • Connect has ready-made configs for Claude, Cursor, and Codex, and a local orbit-waves-mcp command for other clients.
  • One key works in every client.

What to ask

A good first sentence: “Open my latest Orbit Waves project, split it, and make it radio-ready for Spotify.” The assistant lists your projects newest first, splits the song, runs the same finish the button runs, and reports the loudness.

Then be specific: “Turn the vocal up 2 dB and add a little room to it.” “Write a volume ramp on the drums over the first eight seconds.” “Compare the original loudness with the mix.” A tool can add effects the page does not put on a button: EQ, compressor, limiter, gate, de-esser, reverb, delay, chorus, saturation, width, and filter, plus buses, sends, and automation.

You stay in charge

The page and the assistant call the same actions on one project document. A change made in chat appears on the open mix within a couple of seconds and lands in History marked Tool. Every batch is one undo, so Command-Z takes back whatever the assistant just did. The tool cannot invent a feature the app does not have.

Questions

Which assistants work?

Any MCP client that can send a bearer key over streamable HTTP: Claude Code and Claude Desktop, Cursor, Codex, and others. Clients that only speak stdio use the orbit-waves-mcp command.

Is MCP on the free plan?

Connected tools come with the €19 monthly plan. Everything the tool can do, you can also do yourself on the page.
