Nothing serious here today

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

JustOneAPI — questions

Answers built from our own checks of this server.

What can JustOneAPI do?
It exposes 6 tools, read directly from the server on our last check. Among them: call_endpoint, get_account_balance, get_endpoint_schema, get_usage_summary, list_platforms, search_endpoints. 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 JustOneAPI working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 292 ms. The bar chart above shows every period we have measured.
How do I connect JustOneAPI?
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.
Does JustOneAPI need an API key?
No. JustOneAPI completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is JustOneAPI?
It answers our handshake in 292 ms on average, which is faster than 46% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is JustOneAPI open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 6 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.justoneapi.com, which runs on its operator's own terms.
