## Verdicts

**ElevenLabs Music API.** Vocals and lyrics in several languages, or forced instrumental, with length set from 3 to 600 seconds. Music API is disabled on the Free plan and pay-as-you-go needs a card.

**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.

## Before you call either

### ElevenLabs Music API

1. Strip artist and song names from user prompts before calling, or the request breaks the Music Terms
2. Pin `model_id`. The API default is still `music_v1`
3. Set `music_length_ms` and `force_instrumental: true` for background beds. Billing is by minute of audio
4. On 429, retry `system_busy` with exponential backoff, but treat `too_many_concurrent_requests` as a plan limit and queue
5. Don't plan on the MCP server for music. Its documented tools cover agents and speech

### 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
