Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

GroundTruth Field Evidence — questions

Answers built from our own checks of this server.

What can GroundTruth Field Evidence do?

It exposes 4 tools, read directly from the server on our last check. Among them: ground_truth_info, human_do, review_task, task_status. 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 Field Evidence working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 12 of 92 checks got a reply (13.0%), average response time 686 ms. The bar chart above shows every period we have measured.

The registry lists GroundTruth Field Evidence as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect GroundTruth Field Evidence?

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 GroundTruth Field Evidence need an API key?

No. GroundTruth Field Evidence 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 GroundTruth Field Evidence?

It answers our handshake in 686 ms on average, which is faster than 13% 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.

Is GroundTruth Field Evidence open source?

We cannot say either way: written in Solidity, 0 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
