Nothing serious here today

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

LabelTruth — questions

Answers built from our own checks of this server.

What can LabelTruth do?
It exposes 4 tools, read directly from the server on our last check. Among them: cheapest_in_form, get_product, list_elements, list_forms. 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 LabelTruth working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 61 of 61 checks got a reply (100.0%), average response time 516 ms. The bar chart above shows every period we have measured.
How do I connect LabelTruth?
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 LabelTruth need an API key?
No. LabelTruth 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 LabelTruth?
It answers our handshake in 516 ms on average, which is faster than 22% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
