Darwin-owned Files — questions

Answers built from our own checks of this server.

What can Darwin-owned Files do?

It exposes 5 tools, read directly from the server on our last check. Among them: csv_to_xlsx, event_brief_to_ics, markdown_to_pdf, xlsx_to_csv, zip_text_files. 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 Darwin-owned Files 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 521 ms. The bar chart above shows every period we have measured.

How do I connect Darwin-owned Files?

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 Darwin-owned Files need an API key?

No. Darwin-owned Files completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Darwin-owned Files?

It answers our handshake in 521 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.
