## 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 2026-09-22.

- **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**: 88/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 608 tokens (~50/item across 12 items; 3 tools + 9 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 93/100
  - Stability observed for 28 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (3)

### `search_documentation` (~120 tokens)

Search Yappy documentation

Full-text search across Yappy documentation and FAQ. Use this to answer how-to and troubleshooting questions: installing Yappy, granting macOS permissions, a hotkey that does nothing, choosing an LLM backend, configuration keys, personas, or exactly what stays on-device. Results carry an excerpt you can quote and a URL you can cite.

Input parameters:

- `limit` (integer): How many results to return.
- `query` (string, required): What to search for, in plain words.
- `type` (string): Narrow the search to documentation pages or FAQ entries.

### `get_documentation_page` (~65 tokens)

Read a Yappy documentation page

Fetch one full Yappy documentation page as markdown, by slug. Use this after search_documentation when an excerpt is not enough and you need the whole page — for example the complete configuration reference or the full privacy model.

Input parameters:

- `slug` (string, required): Which page to fetch.

### `list_documentation_pages` (~66 tokens)

List Yappy documentation pages

List every page in the Yappy documentation with its slug, title, and one-line summary, so you can pick the right one to read instead of guessing a slug.

Input parameters:

- `include_summaries` (boolean): Include each page's one-line summary alongside its slug and title.
