Is stackexchange-mcp-server live?

Yes — it answered the hub's last check (checked 10m ago). It answered 100% of checks over the last 30 days.

Is stackexchange-mcp-server free to use?

Yes — the hub reached it with no key and no payment.

What tools does stackexchange-mcp-server have?

5 tools: stackexchange_search_questions, stackexchange_get_user, stackexchange_get_tag_faq, stackexchange_get_thread, stackexchange_list_sites.

Is stackexchange-mcp-server safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• stackexchange_list_sites reads open 16h ago

  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 reads unknown 8h ago

  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.

• stackexchange_get_user reads unknown 8h ago

  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_get_tag_faq reads unknown 16h ago

  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.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
