## 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**: 57/100
  - 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 2 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 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**: 51/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 625 tokens (~312/item across 2 items; 2 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**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 62, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (2)

### `qt_documentation_search` (~422 tokens)

Call qt_documentation_search when: (a) you're about to claim a signal/slot/property/default exists, (b) the API is in Qt 6.7+ or a non-core module (MQTT, OPC UA, Network Auth, etc), (c) the user used the words 'docs', 'official', 'verify', or 'check'. Skip when: the question is about basic QString/QObject/signal-slot syntax.

Input parameters:

- `filter` (string): Optional: Filter by document type. Default is 'all'. Note: 'function' returns the class reference page that contains the function (there are no function-level pages); for QML, use 'qml'.
- `intent` (string): Optional: Prioritizes (not filters) results by type. 'api'=class reference, 'tutorial'=how-to guides, 'guide'=overviews, 'concept'=explanations, 'example'=code samples, 'migration'=porting guides.
- `keywords` (array): Optional: Array of keywords to search for. Results match ANY keyword. Example: ["button", "signal", "connect"]. Alternative to 'query' for better multi-term matching.
- `max_results` (integer): Optional: Maximum number of results to return (1-10). Default is 3.
- `module` (string): Optional: Limit search to specific Qt module (e.g., 'qtcore', 'qtwidgets', 'qtqml', 'qtquick', 'qtnetwork')
- `product` (string): Optional: Limit search to a specific documentation product (e.g. 'qt', 'qtcreator', 'pyside6'). Omit to search all products.
- `query` (string): Search query for Qt documentation (e.g., 'Animation', 'QTimer', 'signal slot'). Optional if 'keywords' is provided.
- `version` (string): Optional: Qt version to search (e.g., '6.10.0', '6.9.0'). Defaults to latest installed version if not specified.

### `qt_documentation_read` (~119 tokens)

Read the full content of a specific Qt documentation page. Use the filename shown in search results.

Input parameters:

- `file` (string, required): Filename of the Qt documentation page. Use ONLY the filename from search results (e.g., 'signalsandslots.html' NOT full paths with version numbers). Module paths like 'qtcore/qobject.html' also work.
- `version` (string): Optional: Qt version to read from (e.g., '6.10.0', '6.9.0'). Defaults to latest installed version if not specified.
