is-real-biz — questions

Answers built from our own checks of this server.

What can is-real-biz do?

It exposes 1 tools, read directly from the server on our last check. Among them: check_business. 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 is-real-biz working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 83 of 91 checks got a reply (91.2%), average response time 97 ms. The bar chart above shows every period we have measured.

Is is-real-biz still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect is-real-biz?

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.

Does is-real-biz need an API key?

No. is-real-biz completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is is-real-biz?

It answers our handshake in 97 ms on average, which is faster than 92% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
