## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% +updated-12d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 89/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 5 of 5 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: stackexchange_get_user (destructiveHint); stackexchange_list_sites (destructiveHint); stackexchange_search_questions (destructiveHint); …
- pass `tools.token_cost`: about 1,982 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: deps.dev does not know @cyanheads/stackexchange-mcp-server@0.1.16, @cyanheads/stackexchange-mcp-server@0.1.16

- tools: 5, about 1,982 tokens to load them all
- tool set hash: fe232bd4e90b4e8fb107cf29d984529d
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.cyanheads/stackexchange-mcp-server.svg)](https://protogrid.dev/servers/io.github.cyanheads/stackexchange-mcp-server)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `stackexchange_get_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. Results past the pageSize cap are reachable with the `page` parameter. 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.
- `stackexchange_get_thread`: Fetch a complete Q&A thread — question body and all answers, accepted answer first then sorted by score, rendered as clean markdown with fenced code blocks. 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.
- `stackexchange_get_user`: Fetch a Stack Exchange user profile by numeric user ID: reputation, badge counts, answer and question counts, account and last-access dates, and top tags by answer score. 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.
- `stackexchange_list_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.
- `stackexchange_search_questions`: Search questions across a Stack Exchange site. Returns ranked questions with title, score, answer count, accepted status, tags, ask and last-activity dates, and a short excerpt of the question body — not the full body. Results supply question_id values for stackexchange_get_thread, which fetches the full question body and all answers. Results past the pageSize cap are reachable with the `page` parameter. Use the `site` parameter to target a specific community (e.g. "stackoverflow", "superuser", "unix"); call stackexchange_list_sites to discover valid site values.
