Tools have disappeared from this server

A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

Agent Preflight — questions

Answers built from our own checks of this server.

What can Agent Preflight do?
It exposes 7 tools, read directly from the server on our last check. Among them: access_check, api_discovery, batch_preflight, change_check, preflight, premium_preflight and 1 more. 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 Agent Preflight 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 162 ms. The bar chart above shows every period we have measured.
Did Agent Preflight ever remove tools?
Yes. agent402_mcp, agent_scrape_mcp, arbitrage_check, one_cent_mcp and 1 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect Agent Preflight?
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 Agent Preflight need an API key?
No. Agent Preflight completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Agent Preflight?
It answers our handshake in 162 ms on average, which is faster than 80% 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.
