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. How we score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability51
- AI-judged instruction clarity (good).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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.

qt_documentation_read ~119
Read the full content of a specific Qt documentation page. Use the filename shown in search results.
| Name | Type | Req | Description |
|---|---|---|---|
| file | string | yes | 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. |
No output schema declared.
No examples provided.
qt_documentation_search ~422
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |
