stackexchange
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. 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, 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.
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, 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.

Stackexchange MCP Server — questions

Answers built from our own checks of this server.

What can Stackexchange MCP Server do?
It exposes 5 tools, read directly from the server on our last check. Among them: stackexchange_get_tag_faq, stackexchange_get_thread, stackexchange_get_user, stackexchange_list_sites, stackexchange_search_questions. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Stackexchange MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 366 ms. The bar chart above shows every period we have measured.
How do I connect Stackexchange MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Stackexchange MCP Server need an API key?
No. Stackexchange MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Stackexchange MCP Server?
It answers our handshake in 366 ms on average, which is faster than 38% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Stackexchange MCP Server?
The npm package @cyanheads/stackexchange-mcp-server was installed 91 times in the last week. Week over week that is -24%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Stackexchange MCP Server open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
