Why the edge:
- Maintenance & community, Suno MCP +57: SOUNDRAW API 3 (No dated release, changelog entry or API change found. The 7 August 2026 blog post names `/api/v3` but no version history (0). No dated entries in the last 90 days (0). No public changelog. Contact is a call booking or form, and the help centre answers FAQs (3). No official SDK (0). No package 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.)
- Security & auth, Suno MCP +29: SOUNDRAW API 20 (A single bearer token issued by SOUNDRAW per licensee, which the licence (clause 3.10) forbids sharing, rather than keys you manage yourself. No scopes, rotation or revocation documented (10). No least-privilege mode (0). Returns generated audio, no untrusted content (10). No per-call log or audit trail found (0). No security.txt (404 at /.well-known/security.txt and /security.txt), disclosure policy, bug bounty or certification found (0).); Suno MCP 49 (OAuth on Suno's own authorisation server, with authorisation code and PKCE S256, refresh tokens, a revocation endpoint, open client registration, client ID metadata documents and bearer tokens in the header only. The resource lists eight scopes and keeps spending credits in its own `credits:spend` scope (30 of 30). The scopes separate reading, searching, writing the library and spending, but no read-only connection, spending cap or confirmation step is documented, and the consent screen wasn't seen (6 of 20). Results come from the user's own library and Suno's generation, with lyrics and titles that may come from shared or remixed songs, and no injection guidance (8 of 15). Every song lands in the library and the credit balance can be checked, with no per-call log (5 of 15). No security.txt on suno.com or api.suno.com, and no disclosure policy, bug bounty or certification found (0 of 20). Total 49.)
- Payments & pricing, Suno MCP +22: SOUNDRAW API 10 (No x402, MPP or L402 (0). Plan prices are public, API Starter $29.99 a month for up to 100 songs and API Pro $300 a month for up to 1,000 songs with a 6-month minimum, with no per-call price (10). The help centre now reads "Free 2-week trial with no commitment" but doesn't say whether a card is needed, and the API page names no trial, so we don't count it (0). Access needs a sign-up or a sales call (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.)
- Schema & documentation, Suno MCP +16: SOUNDRAW API 8 (The API reference isn't public. It arrives with a token after sign-up or a sales call, so there's no contract (0), no endpoint descriptions (0), no typed inputs or enums (0) and no changelog (0) we could read. A SOUNDRAW blog post of 7 August 2026 shows one compose request body and one result body for `soundraw.io/api/v3`, with no error responses (3 of 15). soundraw.io has an llms.txt, but it describes the company and products and links only the API landing page (5). Total 8.); 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.)
- Transparency & trust, Suno MCP +11: SOUNDRAW API 44 (Closed service. The API licence agreement spells out end-user rights, a revenue share of 70 per cent on resold unmodified tracks and 50 per cent on heavily altered ones, and Singapore law (15). It says SOUNDRAW keeps the copyright in the songs (clause 2.4), while the 7 August 2026 blog post says tracks are owned by the user. The privacy policy (Japan's personal information act) and a separate GDPR policy list what's collected and users' rights, but give retention only as the period necessary, are undated and link no DPA. The licence adds a 72-hour deletion of generated songs and says end-user data needs explicit consent and a separate agreement. The statements agree, without fixed periods for account data (14 of 30). No deprecation policy or dated notices (0). No subprocessor list or data locations found (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.)
- Agent ergonomics, Suno MCP +7: SOUNDRAW API 7 (With no public API reference there's nothing to grade on response size, pagination, errors or retries, so those lines score as not found (0). SOUNDRAW's 7 August 2026 guide says `length` in seconds is the only required field and the API picks the rest when they're left out. No official SDK. Scored below the usual 8 because this comes from a blog post, not the reference (7 of 15). Generation is asynchronous, a request returns a `request_id` that the caller polls until the track is ready, and download links expire 72 hours after generation.); 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.)
