Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

drinking
drinking_water
Public water systems serving a US state + county and/or city, with health-based SDWA violation summaries. Matching is approximate (service boundaries are not public); the user's water bill names their actual utility.
environment
environment_near
Federal environmental records within a radius of a US location: Superfund/NPL sites, TRI toxic-release facilities, and facilities currently flagged for significant noncompliance. Pass EITHER a street address (geocoded via the US Census geocoder) OR lat/lon coordinates.

Groundtruth — questions

Answers built from our own checks of this server.

What can Groundtruth do?
It exposes 2 tools, read directly from the server on our last check. Among them: drinking_water, environment_near. 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 Groundtruth 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 405 ms. The bar chart above shows every period we have measured.
How do I connect Groundtruth?
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 Groundtruth need an API key?
No. Groundtruth completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Groundtruth?
It answers our handshake in 405 ms on average, which is faster than 35% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
