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.

localize.dev — questions

Answers built from our own checks of this server.

Why is there no tool list for localize.dev?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is localize.dev working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 53 of 53 checks got a reply (100.0%), average response time 708 ms. The bar chart above shows every period we have measured.
How do I connect localize.dev?
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 localize.dev?
No API key is involved. localize.dev 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 localize.dev?
It answers our handshake in 708 ms on average, which is faster than 14% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use localize.dev?
The npm package localize-dev was installed 2 961 times in the last week. Week over week that is -53%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is localize.dev open source?
No, and the distinction matters: it ships its own licence file rather than a standard open-source licence. That makes it source-available — you can read the code, but the terms are the author's own, not one of the recognised open-source licences. Read them before you build on it.
