Hungarian Postcode Validator — questions

Answers built from our own checks of this server.

Why is there no tool list for Hungarian Postcode Validator?
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 Hungarian Postcode Validator 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 469 ms. The bar chart above shows every period we have measured.
How do I connect Hungarian Postcode Validator?
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 will need your own key or an OAuth login: it refuses anonymous clients.
Does Hungarian Postcode Validator need an API key?
Yes. Every time we knock, Hungarian Postcode Validator answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is Hungarian Postcode Validator?
It answers our handshake in 469 ms on average, which is faster than 25% 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.
Is Hungarian Postcode Validator open source?
Yes — written in Python 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.
