## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS check failed: the endpoint is reachable over plaintext HTTP.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 546 tokens (~182/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (3)

### `generate_song` (~278 tokens)

Start generating a song with Suno. Returns immediately with a job_id — a full render takes 1-3 minutes, so this does NOT return audio. After calling this, call wait_for_song with the returned job_id to get the audio URL when ready. Costs 10 tokens, billed only on success.

Input parameters:

- `custom` (boolean): false (default): describe the song and Suno writes everything. true: `prompt` is the literal lyrics, and `tags`/`title` are used.
- `idempotency_key` (string): Optional logical-request id. Reuse it to recover one submit; use a new value to intentionally generate the same song again or retry after a terminal failed job. When omitted, Tunova derives a stable…
- `instrumental` (boolean): If true, generate without vocals.
- `model` (string): Suno model version (v5.5 — the only model). Optional; defaults to v5.5.
- `prompt` (string, required): What the song should be about (simple mode), or the exact lyrics (when custom=true).
- `tags` (string): Style/genre, e.g. 'lofi hip hop, mellow, rainy'. Most useful in custom mode.
- `title` (string): Song title (custom mode).

### `wait_for_song` (~124 tokens)

Wait for a song job to finish and return the audio when ready. Polls server-side for up to ~45 seconds. If the song is ready, returns the clips with audio URLs. If it is still rendering, returns its status so you can call wait_for_song again with the same job_id. Safe to call repeatedly — it only reads status, never starts a new song.

Input parameters:

- `job_id` (string, required): The job_id returned by generate_song.
- `max_wait_seconds` (number): How long to wait before returning (default 45, max 55).

### `check_song` (~63 tokens)

Get the current status of a song job by job_id — a single check with no waiting. Returns the audio URLs if complete, an error if it failed, or 'processing' if still rendering.

Input parameters:

- `job_id` (string, required): The job_id returned by generate_song.
