Nothing serious here today

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

FlightSweeper — questions

Answers built from our own checks of this server.

What can FlightSweeper do?

It exposes 4 tools, read directly from the server on our last check. Among them: get_challenge_capabilities, get_flight_tool_contracts, get_safety_model, get_sandbox_inventory. 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 FlightSweeper 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 243 ms. The bar chart above shows every period we have measured.

How do I connect FlightSweeper?

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 FlightSweeper need an API key?

No. FlightSweeper completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is FlightSweeper?

It answers our handshake in 243 ms on average, which is faster than 62% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is FlightSweeper open source?

Yes — it is published under the MIT licence, written in JavaScript 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.
