Verdicts

Mubert API

Hosted MCP server with 21 tools and OAuth 2.1 with PKCE, in the official registry under com.mubert. Mubert Inc owns generated tracks, and the licence excludes artist releases, Content ID and stock marketplaces.

MusicGPT API

A public OpenAPI 3.1 file with 27 operations, llms.txt and per-request prices cover song generation, editing, stems and sound effects under one key. No status page, SLA, security.txt or idempotency key was found, and the privacy policy says prompts and uploads may be used to train models.

Before you call either

Mubert API

  1. Search the library before generating. A match costs no generation
  2. Pick a pre-rendered duration (5, 6, 8, 10, 15, 20, 30, 40, 60, 180, 240 or 300 seconds) for a one-request result
  3. Download tracks straight away. URLs expire after 900 seconds by default
  4. Treat stream URLs as secrets. They carry the customer access token

MusicGPT API

  1. Send the key as the raw Authorization header value. The docs show no Bearer prefix
  2. Budget two songs for each music request. POST /v2/MusicAI returns two versions and the price is per song
  3. Save task_id and poll GET /v1/byId with conversionType, or set webhook_url. Music AI V2 sends up to seven webhooks a request
  4. Pass model explicitly. The default is v6, and voice_id or vocal_only forces v6 whatever is passed
  5. Do not retry a create blindly after a timeout. No idempotency key is documented, so a retry may bill again

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
