Analyze Mixes from Your Own Tools with the Agent API
The Agent API lets your own tools and AI agents upload a mix, run an analysis and read the score. There is also an MCP server.
Overview
MixMaster Pro is the living Mix Intelligence platform for producers. Analyses stay in your Mix Library, revisions compare on the same mix, references save to your account, and Maya on Pro+ coaches from your bound report - connected workflows instead of one-time uploads. The same account also runs Audio Tools and Workflow Builder: AI mastering, stem splitting, karaoke, a capella, guitar chords and lyrics, Sound FX, song generation, voice cleanup, and audio restoration.
Reference docs are at /developers (Swagger and ReDoc) and /agents. The MCP server is at https://mixmasterpro.io/mcp.
Authentication and limits
- Create an API key in Account > API Key (shown once).
- Exchange it for a 1-hour Bearer token: POST /agent-api/auth/token with the X-Agent-Api-Key header.
- Rate limits per hour: 10 tokens, 30 uploads, 20 analyses (40 analyses a day).
Analyze a mix in four calls
- POST /agent-api/uploads/create to get a presigned upload URL.
- PUT the audio file to that URL.
- POST /agent-api/analyses to start the analysis.
- Poll GET /agent-api/analyses/:id until it completes; the result has the mix score, grade and a link to the full report.
