• check_discovery_documents

  FIRST CALL, needs nothing: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"no_arguments_check_this_hosts_own_discovery_documents","arguments":{}}} — Probes 22 documents agents and trust indexes ask for — llms.txt, agent card, owners.json, oauth metadata, mcp.json, apis.json, openapi, robots, sitemap — as served, missing, gated or 200-with-HTML soft-404, and says who asks for each missing one. Refuses private, ephemeral and its own hosts. Example: host='example.com'.

• example

  {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"example","arguments":{}}} — POST that exact body to https://www.pathwren.workers.dev/mcp/doctor 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 — validate_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 — validate_llms_txt on a four-line llms.txt held as a constant in this file: it exercises the H1, the blockquote summary and an H2 link section, which is the whole format — and it fetches nothing, from us or from anyone — and returns exactly the structuredContent a real call returns, not a mock and not a description of one. Use it to see the shape of an answer before you decide what to send. The input is canned from this host's own data; no URL of yours is fetched and no third party is touched. Example: arguments={} runs validate_llms_txt with {"text":"# Site\n\n> One line.\n\n## Docs\n\n- [Guide](https://e.com/g): start here."} and returns its real answer.

• explain_document

  FIRST CALL, needs nothing: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"no_arguments_check_this_hosts_own_discovery_documents","arguments":{}}} — One catalogue entry: what the document is for, the named clients observed asking this host for it with dates and the status they took, what a 404 costs, and the spec URL. No argument lists all 22. Example: name='owners.json' names the bot that asks for it twice.

  shallow
• llms_txt_from_sitemap

  FIRST CALL, needs nothing: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"no_arguments_check_this_hosts_own_discovery_documents","arguments":{}}} — Paste sitemap.xml, or one URL per line, and get a draft llms.txt: URLs grouped into H2 sections by path, titles from slugs, lastmod kept, and a TODO wherever only you can write the sentence. A sitemap index is reported as one. Example: xml='https://e.com/docs/a\nhttps://e.com/blog/b'.

  shallow
• no_arguments_check_this_hosts_own_discovery_documents

  TAKES NO ARGUMENTS. POST {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"no_arguments_check_this_hosts_own_discovery_documents","arguments":{}}} to https://www.pathwren.workers.dev/mcp/doctor — the answer is the whole agent-discovery catalogue checked against THIS host — every document this server tracks, whether this host serves it, its size and content type, which ones are missing, and the part only this server can add: the named clients it has watched ask for each file, when, and the status that request took. There is nothing to fill in: the input schema is literally empty, `arguments: {}` and no `arguments` key at all both work, and the subject is a file this host already publishes, so the answer does not depend on you at all. No key, no account, no OAuth, no session to open first, read-only, and nothing for you to invent. Nothing is fetched to build it — no request leaves this edge, and none is made to you. whoami and example are here too and take nothing either. Every other tool on this server wants a file pasted in; this one wants nothing. The siblings answer one question each under the tool named beside them: /mcp (whoami), /mcp/lint (whoami), /mcp/triage (no_arguments_triage_this_hosts_own_crawler_log), /mcp/robots (no_arguments_lint_this_hosts_robots_txt), /mcp/netcheck (no_arguments_report_the_crawler_ip_ranges_this_host_mirrors), /mcp/markdown (markdown_lane_self_report). Example: the complete call, exactly as written, nothing to fill in — {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"no_arguments_check_this_hosts_own_discovery_documents","arguments":{}}} returns a present/missing verdict per tracked document with its byte size, the group each belongs to, the score out of the catalogue, and the observed askers per document with the date and status each one got.

• validate_agent_card

  FIRST CALL, needs nothing: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"no_arguments_check_this_hosts_own_discovery_documents","arguments":{}}} — Validates a pasted /.well-known/agent-card.json against the nine fields A2A marks required and each skill's id/name/description/tags, and warns on capabilities declared true that a reader will then try. Example: json='{"name":"a"}' returns the eight missing fields.

  shallow
• validate_llms_txt

  FIRST CALL, needs nothing: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"no_arguments_check_this_hosts_own_discovery_documents","arguments":{}}} — Checks pasted llms.txt against the format: one H1, a blockquote summary, H2 sections of `- [name](url): notes`. Errors and warnings with line numbers and fixes, plus the parsed links. Text in, nothing fetched. Example: text='# Site' warns it has no summary and no sections.

  shallow
• whoami

  {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"whoami","arguments":{}}} — POST that to https://www.pathwren.workers.dev/mcp/doctor and the answer is the user-agent you sent, the class this host's own instrument books it as, whether we have logged you here before — and the part only this server can answer: which of the discovery documents this catalogue tracks (llms.txt, the agent card, mcp.json, apis.json, oauth-protected-resource…) a client like yours has been observed asking THIS host for, when, and what status it took. Takes no arguments. Safe to call. Deterministic. Touches no third party. Nothing is fetched to build it: every fact comes from the headers on your own request or from a file this host already publishes. Only this server answers the last part — its five siblings answer one other question each about you, same empty arguments, each under the tool named beside its path: /mcp (whoami), /mcp/lint (whoami), /mcp/triage (no_arguments_triage_this_hosts_own_crawler_log), /mcp/robots (no_arguments_lint_this_hosts_robots_txt), /mcp/netcheck (no_arguments_report_the_crawler_ip_ranges_this_host_mirrors), /mcp/markdown (markdown_lane_self_report) on https://www.pathwren.workers.dev. Example: arguments={} returns your user-agent, your address, the class we book you as, whether we have seen you here before, and which agent-discovery documents this host has watched a client like yours ask for — the dates, and the status each request took.
