## 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 2026-10-23.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (convert_voice).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 73/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 527 tokens (~58/item across 9 items; 9 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (11% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (9)

### `get_profile` (~19 tokens)

Connected account

Identify the HanoLab account connected to these tools.

Output parameters:

- `id` (string)
- `name` (string)

### `get_credits` (~24 tokens)

Credit balance

Read the connected account’s plan and available credits. Does not purchase credits.

### `list_voices` (~37 tokens)

Saved voices

List the connected user’s own saved voices and whether they are ready. If none are ready, open voicelab to create one.

### `create_upload_link` (~61 tokens)

Upload audio

Create a private one-hour browser upload link. Ask the user to open it, choose an audio file or MP4 and return here. Requires the same HanoLab account; no credits are spent. This tool cannot read local paths or ChatGPT attachments directly.

### `list_audio` (~31 tokens)

Uploaded audio

List recent audio uploaded through this connection. Use the exact audio_id, never a local path or an arbitrary URL.

### `prepare_voice_conversion` (~75 tokens)

Estimate voice conversion

Prepare a fixed quote for uploaded audio and a ready owned voice. No credits are spent. Explain estimated_credits, obtain the user’s budget and explicit confirmation, then use convert_voice with this exact quote_id.

Input parameters:

- `audio_id` (string, required)
- `full_song` (boolean)
- `voice_id` (string, required)

### `convert_voice` (~84 tokens)

Convert voice

Spend HanoLab credits to submit the prepared conversion ONLY after the user confirms its cost and budget. Reuse the exact quote_id after interruption: repeated calls return the original task without another debit. A failed task needs a separate user decision before a new quote.

Input parameters:

- `confirmed` (boolean, required)
- `max_credits` (integer, required)
- `quote_id` (string, required)

### `get_task` (~56 tokens)

Conversion status and results

Check an owned task and return completed audio links. Refreshes worker status and may persist completion or a failure refund. Poll about every 10 seconds; do not submit a new paid task while waiting.

Input parameters:

- `task_id` (string, required)

### `list_conversions` (~32 tokens)

Recent conversions

Find recent conversions submitted with this connection. Use get_task to refresh a task. This does not start new tasks.
