Polytranslator does not always answer

Over the last week it answered 99.4% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

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 88 of 91 checks got a reply (96.7%), average response time 428 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 in the form 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 428 ms on average, which is faster than 29% 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?
The code is open source: it is published under the MIT licence and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at polytranslator.com, which runs on its operator's own terms.
