## 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**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - 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**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 841 tokens (~105/item across 8 items; 8 tools + 0 resources), lean.
  - 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (8)

### `start_trial` (~78 tokens)

Start a temporary, email-free Pulse trial. Returns a short-lived private API key with enough banked tokens for one short URL-based v1 analysis. No Stripe Checkout session is created.

Output parameters:

- `account_type` (string): The account type created by this tool.
- `analyze_path` (string): REST path for authenticated analysis.
- `api_key` (string): Temporary Pulse API key for the trial account. Treat as private; do not print it in public logs, screenshots, GitHub issues, shared chats, or directory examples.

### `analyze_track` (~218 tokens)

Run audio analysis on a public audio URL. Requires estimate_cost to be called first (job_estimate_id). Requires PULSE_API_KEY. Before calling, you MUST confirm with the user that they have a lawful basis to submit this audio for analysis. For a user-requested folder, project, playlist, or batch, one confirmation can cover every track in that scope. Returns job_id — poll get_job_status for results.

Input parameters:

- `attestation_confirmed` (boolean, required): Set to true ONLY after the user has confirmed they have rights, permission, lawful access, or another legal basis to submit this audio, or the current user-requested batch/folder/project containing i…
- `audio_url` (string, required): Public URL of the audio file.
- `job_estimate_id` (string, required): The job_estimate_id returned by estimate_cost. Must not be expired (30 min TTL).

- `upgrade_path` (string)

### `request_payment_link` (~160 tokens)

Generate a one-time Stripe payment page for users without a Pulse account. Before calling, you MUST confirm with the user that they have a lawful basis to submit this audio for analysis; for a user-requested batch/folder/project, one confirmation can cover that scope. Present the payment_url to the user as a link. Analysis begins automatically after payment. Poll get_job_status with the returned job_id.

Input parameters:

- `attestation_confirmed` (boolean, required): Set to true ONLY after the user has confirmed they have rights, permission, lawful access, or another legal basis to submit this audio, or the current user-requested batch/folder/project containing i…

Input parameters:

- `include_waveform_data` (boolean): Optional. Defaults to false so chat agents receive a compact waveform summary plus result_url. Set true only if raw waveform samples are needed.
- `include_waveform_image` (boolean): Optional. Defaults to true. When the job has waveform data, include a server-rendered SVG as MCP image content so the client can display it without fetching a URL.
