## Tools
- stackexchange_list_sites (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. Endpoint: https://stackexchange.caseyjhand.com/mcp
- stackexchange_search_questions (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. Endpoint: https://stackexchange.caseyjhand.com/mcp
- stackexchange_get_tag_faq (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. Endpoint: https://stackexchange.caseyjhand.com/mcp
- stackexchange_get_user (Get Stack Exchange User Profile) - 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. Endpoint: https://stackexchange.caseyjhand.com/mcp
- stackexchange_get_thread (Get Stack Exchange Q&A 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.
