Available tools 1

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

url
read_url
Fetch a document by URL and return its text: PDFs (arXiv papers, reports), web pages, Word, Excel, PowerPoint, OpenDocument, EPUB, Markdown and other text. Use it to summarize, quote or answer questions about a link. Returns title, kind, page count, character count, whether the text was truncated, and the text. maxChars caps the text (default 100,000, up to 400,000). No account needed; a free hourly allowance, then an x402 reader pass.

readm3 — questions

Answers built from our own checks of this server.

What can readm3 do?
It exposes 1 tools, read directly from the server on our last check. Among them: read_url. 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 readm3 working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 12 of 13 checks got a reply (92.3%), average response time 372 ms. The bar chart above shows every period we have measured.
How do I connect readm3?
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 readm3 need an API key?
No. readm3 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is readm3?
It answers our handshake in 372 ms on average, which is faster than 37% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
