TidyData Tools — questions

Answers built from our own checks of this server.

What can TidyData Tools do?

It exposes 49 tools, read directly from the server on our last check. Among them: add_business_days, airport_distance, airport_info, airport_search, business_days_between, check_url_status and 43 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 TidyData Tools mostly used for?

Its tools cluster around convert, extract and airport. 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 TidyData Tools 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 305 ms. The bar chart above shows every period we have measured.

How do I connect TidyData 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 TidyData Tools need an API key?

No. TidyData Tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 49 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is TidyData Tools?

It answers our handshake in 305 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is TidyData Tools open source?

Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
