llms.txt Readiness — questions

Answers built from our own checks of this server.

What can llms.txt Readiness do?

It exposes 31 tools, read directly from the server on our last check. Among them: agent-ads-index, agent-tool-index, browser-url-ok, calc-eval, citation, compatibility and 25 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 llms.txt Readiness mostly used for?

Its tools cluster around agent and status. 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 llms.txt Readiness 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 129 ms. The bar chart above shows every period we have measured.

How do I connect llms.txt Readiness?

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 llms.txt Readiness need an API key?

No. llms.txt Readiness completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 31 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is llms.txt Readiness?

It answers our handshake in 129 ms on average, which is faster than 87% 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.

Is llms.txt Readiness open source?

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