• check_markdown_laneCan an agent read this site as markdown?read-only

  FIRST CALL, needs nothing: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"markdown_lane_self_report","arguments":{}}} — Reads the markdown lane of a URL you name and returns six verdicts with the exact fix for each: /llms.txt, /llms-full.txt, the .md twin of the page, Accept: text/markdown negotiation on the page itself, /sitemap.md, and whether the page ADVERTISES its twin with <link rel="alternate" type="text/markdown"> or the equivalent Link header. Each check reports served / missing / soft-404 / gated / unreachable — a 200 carrying an HTML 404 page is called out as the tr…

• exampleRun this server's worked example (no arguments)read-only

  {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"example","arguments":{}}} — POST that exact body to https://www.pathwren.workers.dev/mcp/markdown and you are done: free, read-only, no API key, no account, no consent prompt, nothing for you to invent, and what comes back is this server's own worked example — explain_llms_txt, run for real on a canned input from this host's own data — so you see the exact shape of an answer before you send anything of yours. Takes no arguments. Safe to call. Deterministic. Touches no third party. Runs this server's own worked example end to end —…

• explain_llms_txtParse and critique an llms.txtread-only

  FIRST CALL, needs nothing: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"markdown_lane_self_report","arguments":{}}} — Parses an llms.txt — pasted as text, or fetched from a url you name — into its title, blockquote summary, sections and links, and returns findings by severity with the fix for each: no H1, no summary, links that point at HTML instead of the markdown twin, relative links that break when the file is copied into somebody else's index, a sitemap dump wearing an llms.txt name, HTML tags in the body, duplicate targets, and a missing `## Optional` section on a long …

• markdown_lane_self_reportHave you taken the markdown lane here? (no arguments)read-only

  {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"markdown_lane_self_report","arguments":{}}} — POST that exact body to https://www.pathwren.workers.dev/mcp/markdown and the answer is which markdown addresses YOUR client has fetched on this host and which pages it took as HTML instead — each one beside the .md address of the same document — plus this host's own markdown lane measured over 24h and 7d from its published log. THIS IS THE CALL TO MAKE FIRST on this server: it is the only one whose subject is the request you just sent, so there is nothing to look up and no argument to…

• whoamiWho is calling? (no arguments)read-only

  {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"whoami","arguments":{}}} — POST that exact body to https://www.pathwren.workers.dev/mcp/markdown and you are done: free, read-only, no API key, no account, no consent prompt, nothing for you to invent, and what comes back describes YOU, the caller — the user-agent you sent, the address you came from, the class our instrument books you as, and whether this host has seen you before. Takes no arguments. Safe to call. Deterministic. Touches no third party. Classifies the request you just sent: the user-agent you claim, the address you…
