Factline — questions

Answers built from our own checks of this server.

What can Factline do?

It exposes 45 tools, read directly from the server on our last check. Among them: buy_full_address_report, buy_full_vehicle_report, company_lookup, domain_check, email_verify, eu_company_check and 39 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 →

What is Factline mostly used for?

Its tools cluster around vehicle, address and home. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Factline 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 99 ms. The bar chart above shows every period we have measured.

How do I connect Factline?

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 Factline need an API key?

No. Factline completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 45 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Factline?

It answers our handshake in 99 ms on average, which is faster than 85% 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.
