## 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**: 66/100
  - 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 5 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1144 tokens (~228/item across 5 items; 5 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.
  - 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 (5)

### `stackexchange_list_sites` (~118 tokens)

List Stack Exchange Sites

Enumerate all sites in the Stack Exchange network — name, api_site_parameter, audience, and URL. The api_site_parameter value is what other tools accept as the `site` input (e.g. "stackoverflow", "superuser", "serverfault"). Results are fetched live and optionally filtered by name. Use this tool to discover valid site parameters before calling other stackexchange_* tools.

Input parameters:

- `filter` (string): Optional case-insensitive name filter — returns only sites whose name contains all provided tokens. Omit to return all sites.

Output parameters:

- `notice` (string): Actionable guidance when results are empty or filtered.
- `quotaMax` (number): Maximum API quota calls per day (300 keyless, ~10,000 with API key).
- `quotaRemaining` (number): Remaining API quota calls for the current day.
- `sites` (array): Stack Exchange network sites matching the optional name filter.
- `totalCount` (number): Total number of sites returned after filtering.

### `stackexchange_search_questions` (~304 tokens)

Search Stack Exchange Questions

Search questions across a Stack Exchange site. Returns ranked questions with title, score, answer count, accepted status, tags, and excerpt — no bodies at this stage. Results supply question_id values for stackexchange_get_thread, which fetches the full question body and all answers. Use the `site` parameter to target a specific community (e.g. "stackoverflow", "superuser", "unix"); call stackexchange_list_sites to discover valid site values.

Input parameters:

- `acceptedOnly` (boolean): When true, return only questions that have an accepted answer.
- `minScore` (integer): Minimum question score — excludes questions with lower scores. Setting minScore orders results by score (votes), which may differ from the requested sort.
- `pageSize` (integer): Number of results to return (1–30, default 10).
- `query` (string, required): Full-text search query (e.g. "python async generator send value").
- `site` (string): Stack Exchange site to search — use the api_site_parameter value (e.g. "stackoverflow", "superuser", "serverfault"). Defaults to "stackoverflow". Call stackexchange_list_sites to discover valid value…
- `sort` (string): Result ordering: "relevance" (default, best match), "votes" (highest score first), "activity" (most recently active), "newest" (most recently created).
- `tags` (array): Filter results to questions with all specified tags.

Output parameters:

- `attribution` (string): Content license notice. Stack Exchange content is licensed under CC BY-SA 4.0 and requires attribution.
- `cap` (number): The pageSize cap applied to this request.
- `notice` (string): Actionable guidance when results are empty or filtered.
- `questions` (array): Questions matching the search query, ordered by the specified sort.
- `quotaMax` (number): Maximum API quota calls per day (300 keyless, ~10,000 with API key).
- `quotaRemaining` (number): Remaining API quota calls for the current day.
- `shown` (number): Number of results returned.
- `truncated` (boolean): True when results were capped at pageSize.

### `stackexchange_get_tag_faq` (~190 tokens)

Get Stack Exchange Tag FAQ

Fetch the highest-voted answered questions for a tag on a Stack Exchange site — the canonical "best answers in X" list. Returns a question list without bodies; use stackexchange_get_thread to read the full body and answers for any result. Use this tool to find the authoritative community resources on a topic (e.g. tag "javascript" on stackoverflow). Use stackexchange_search_questions for free-text search rather than tag-based browsing.

Input parameters:

- `pageSize` (integer): Number of results to return (1–30, default 10).
- `site` (string): Stack Exchange site — use the api_site_parameter value (e.g. "stackoverflow", "superuser"). Defaults to "stackoverflow". Call stackexchange_list_sites to discover valid values.
- `tag` (string, required): Tag to look up (e.g. "python", "javascript", "docker"). Must match exactly.

Output parameters:

- `attribution` (string): Content license notice. Stack Exchange content is licensed under CC BY-SA 4.0 and requires attribution.

Fetch a Stack Exchange user profile by numeric user ID: reputation, badge counts, top tags by answer score, and account metadata. Useful for credibility context on an answer author — pass the authorUserId from any question or answer in stackexchange_get_thread output. Returns profile fields plus up to 10 top tags by answer score.

Input parameters:

Accepts an integer question ID or a full Stack Exchange question URL (e.g. "https://stackoverflow.com/questions/11227809/why-is-processing-a-sorted-array-faster" or "11227809"). HTML is normalized to markdown automatically; attribution (author + link) included per CC BY-SA 4.0. Get question IDs from stackexchange_search_questions or stackexchange_get_tag_faq.

Input parameters:
