Afterwren missed one check this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Afterwren — questions

Answers built from our own checks of this server.

What can Afterwren do?

It exposes 7 tools, read directly from the server on our last check. Among them: book_search, company_logo, company_profile, company_suggest, encyclopedia_search, geocode and 1 more. 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 Afterwren working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 178 of 178 checks got a reply (100.0%), average response time 89 ms. The bar chart above shows every period we have measured.

How do I connect Afterwren?

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 Afterwren need an API key?

No. Afterwren completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Afterwren?

It answers our handshake in 89 ms on average, which is faster than 88% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
