Agent Data Tools — questions

Answers built from our own checks of this server.

What can Agent Data Tools do?

It exposes 17 tools, read directly from the server on our last check. Among them: arxiv-papers, browser-feature-lookup, describe, domain-intel, earthquake-events, ecb-fx-rates and 11 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 Data Tools 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 127 ms. The bar chart above shows every period we have measured.

How do I connect Agent Data Tools?

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 Agent Data Tools need an API key?

No. Agent Data Tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 17 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Agent Data Tools?

It answers our handshake in 127 ms on average, which is faster than 77% 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.
