Nothing serious here today

Today is the operative word: we check Eldertongue every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Eldertongue — questions

Answers built from our own checks of this server.

What can Eldertongue do?
It exposes 5 tools, read directly from the server on our last check. Among them: beowulf_occurrences, english_to_old_english, identify_form, inflect, lookup_headword. 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 Eldertongue 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 186 ms. The bar chart above shows every period we have measured.
How do I connect Eldertongue?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Eldertongue need an API key?
No. Eldertongue 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 Eldertongue?
It answers our handshake in 186 ms on average, which is faster than 74% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Eldertongue open source?
We cannot say either way: 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
