Mubert API vs Suno MCP

Mubert API 69

OpenAPI document for v3 at music-api.mubert.com, plus a hosted MCP server (25). llms.txt (10). The docs explain the licence, customer and track flows and when a pre-rendered duration returns in one request. We couldn't read the MCP tool descriptions themselves (12). Typed inputs with a fixed list of pre-rendered durations (5 to 300 seconds), intensity, mode and format enums and a playlist_index (12). Request and response examples, but only 200 and 204 documented, no error codes (5). Versioned /api/v3 path, no changelog (5).

Suno MCP 24

Suno doesn't publish the server's tool list, and the tool definitions can be read only after signing in, which this run didn't do, so no contract is public (0 of 25). suno.com/llms.txt is Markdown written for agents but describes the app as of 29 May 2026 and says nothing about the MCP server (5 of 10). suno.com/mcp and the help article list what the server does (songs, covers, extensions, mashups, Speech, uploads, Voices, playlists, credits) without per-tool purpose or when not to call (5 of 20). Typed inputs weren't readable (0 of 15). Three example prompts on suno.com/mcp, and only the 401 with its resource metadata is documented as an error (4 of 15). Dated release notes with an entry for the launch, but no server version or MCP changelog (10 of 15). Total 24.

Mubert API 42

21 MCP tools, in the 11 to 30 band, with no toolsets or read-only subset found (15). Webhooks for generation status from the Startup plan, and a library search to try before generating (15). No error codes or messages documented (0). No idempotency key. The listing's check found the MCP server checks quota before spending, which we couldn't re-read today (5). Sensible defaults and pre-rendered durations, no SDK beyond an agent skill and the MCP server (7).

Suno MCP 14

Tool count and definition size couldn't be read without signing in, so context cost scores as not found (0 of 25). The library:search scope shows library search exists, with no paging or size controls documented (5 of 20). Only the 401 is documented (4 of 20). Idempotency and readOnlyHint or destructiveHint annotations couldn't be read (0 of 20). Setup needs no API key and Suno's examples are plain requests, but required parameters are unknown, and an MCP server needs no SDK (5 of 15). Total 14.

Mubert API 10

No x402, MPP or L402 on the API or MCP server (0). Plan prices are public, $49, $199 and $499 a month, with no per-call price (10). No free API tier. The free tier mentioned in llms.txt is for Mubert Render, not the API (0). Credentials arrive by email after a checkout (0).

Suno MCP 32

No machine payment protocol (0 of 40). Plan prices are public, Pro $10 and Premier $30 a month, and Suno says 50 credits make about 10 songs, but there's no per-song price in money and add-on credit prices sit behind a login (10 of 20). The FAQ says the server works on every plan including Free, which gives 50 credits a day with no card (20 of 20). A person signs up in a browser and approves the connection. Clients can register themselves with the authorisation server, which earns 2 (2 of 20). Total 32.

Mubert API 30

No status page found (0). No readable incident history (5). Quotas published with numbers, monthly generations and streaming minutes per plan (100, 5,000 and 30,000) plus per-customer daily caps and concurrency in the licence object (15). No 429 or retry guidance in the docs (0). No SLA (0). API v3 isn't labelled beta (10).

Suno MCP 13

Read with the hosted lines, because the surface an agent uses is the remote server at api.suno.com/mcp. No official status page was found, and status.suno.com doesn't resolve (0 of 20). No readable incident history (5 of 30). No rate limit is published for the server. The plan table gives generation concurrency, 4 at once in a shared queue on Free and 10 in a priority queue on Pro and Premier, with daily or monthly credits, which we count in part (8 of 15). No 429, Retry-After or backoff guidance (0 of 15). No SLA (0 of 10). The server is labelled beta, and the page asks for early access (0 of 10). Total 13.

Mubert API 48

The hosted MCP server entered the official registry on 2026-09-28, per the listing's check of 2026-09-30 (30). No changelog, so no count of releases in the last 90 days (0). No public changelog and no community channel found (3). Listed in the official MCP registry under the verified com.mubert namespace (15). Hosted service, and the agent-skill repo on GitHub has no stars or issues to judge (0).

Suno MCP 60

The server launched on 28 October 2026, four days before this check (30). The release notes have 13 dated entries since 3 August 2026, one of them about the MCP server (20). Public release notes, a help centre with an MCP category, a support email and a Discord server, with response times not checked (10 of 25). Not in the official MCP registry under a Suno namespace. The two Suno entries there are third-party wrappers (0 of 15). No package to judge (0 of 10). Total 60.

Mubert API 45

Closed service. The terms and llms.txt say plainly that Mubert Inc owns generated music and grants a licence to use it, and list where it can't go (artist releases on Spotify or Apple Music, Content ID, stock marketplaces) (15). We couldn't read the privacy policy on 2026-10-01, so no retention or training statements were checked (5). No deprecation policy or dated notices found (0). No subprocessor list or data locations found, and the terms and contact page give different Delaware addresses (0).

Suno MCP 55

A closed service whose terms (effective 3 September 2026) are clear on output. Pro and Premier users are assigned Suno's rights in their output, Free users may use theirs only for personal, non-commercial purposes, and the help centre says Suno owns Free-plan songs (15 of 30). The privacy notice (23 June 2026) says submissions, chat information and other content are used to train Suno's models, gives no retention periods, and says nothing specific about what an assistant sends through the MCP server (10 of 30). The terms allow any part of the service to change or stop without notice, and the v6 post says older models will be retired without dates (5 of 20). Data is stored in the United States, and service providers are described by category with no named list (8 of 20). Total 38.
