Nothing serious here today

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

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Polytranslator — questions

Answers built from our own checks of this server.

What can Polytranslator do?

It exposes 6 tools, read directly from the server on our last check. Among them: get_credit_balance, get_document, list_languages, quote_document, translate_document, translate_text. 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 Polytranslator working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 32 of 32 checks got a reply (100.0%), average response time 486 ms. The bar chart above shows every period we have measured.

How do I connect Polytranslator?

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. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to Polytranslator?

No API key is involved. Polytranslator answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is Polytranslator?

It answers our handshake in 486 ms on average, which is faster than 33% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Polytranslator open source?

Yes — it is published under the MIT licence and 0 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.
