  "instructions": "{\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"tools/call\",\"params\":{\"name\":\"no_arguments_check_this_hosts_own_discovery_documents\",\"arguments\":{}}}\n\nPOST that exact body to https://www.pathwren.workers.dev/mcp/doctor and it answers with 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. It is the first call to make here — no key, no account, no OAuth, read-only, and no argument to invent: the tool is named for the fact that it takes none, its input schema is literally empty, and its subject is a file this host already publishes, so the answer is the same for every caller and nothing is fetched to build it.\n\n{\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"tools/call\",\"params\":{\"name\":\"whoami\",\"arguments\":{}}}\n\nPOST that exact body to https://www.pathwren.workers.dev/mcp/doctor and it answers with 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.\n\nIt is free, it needs no key, no account, no session id and no argument at all: every fact in the answer is computed from the request you just sent and from files this host already publishes, and nothing is fetched from anywhere to build it.\n\nEVERY TOOL HERE IS READ-ONLY AND UNAUTHENTICATED. None of them writes anything anywhere, none is ever refused for want of a credential, and each says so in its own annotations (readOnlyHint true, destructiveHint false; openWorldHint marks the ones that read a URL you name). Each also carries the same call again under its `_meta` as an object, so nothing here has to be read as prose to be used.\n\nONLY THIS SERVER ANSWERS THAT PART. There are seven MCP servers here and they answer one question each about you — one zero-argument call each, no key, no account, no session. The middle column is the tool to name at that URL, because several of them answer under a name of their own; whoami is answered by all seven and is never an error, so one identical body still walks the whole family if you prefer that.\n  https://www.pathwren.workers.dev/mcp/doctor    no_arguments_check_this_hosts_own_discovery_documents        which agent-discovery documents this host has watched a client like yours ask for — the dates, and the status each request took  <- you are here\n  https://www.pathwren.workers.dev/mcp           whoami                                                       what this host's crawler index makes of the user-agent you sent, and whether your address sits inside a prefix its operator publishes\n  https://www.pathwren.workers.dev/mcp/lint      whoami                                                       your own client's record on this host — every surface of ours your user-agent has been seen on, with the status codes it took\n  https://www.pathwren.workers.dev/mcp/triage    no_arguments_triage_this_hosts_own_crawler_log               your own request triaged as one line of an access log, by the same parser and the same index that read a whole file\n  https://www.pathwren.workers.dev/mcp/robots    no_arguments_lint_this_hosts_robots_txt                      what this host's own robots.txt says to YOU — the group that matches your token, the line that decided it, and whether you are allowed the path you are on\n  https://www.pathwren.workers.dev/mcp/netcheck  no_arguments_report_the_crawler_ip_ranges_this_host_mirrors  whether the address you are calling from falls inside a prefix a crawler operator publishes, and which prefix from which source\n  https://www.pathwren.workers.dev/mcp/markdown  markdown_lane_self_report                                    whether your own client has ever taken this host's markdown lane — which .md addresses it fetched, and the markdown address of every page it took as HTML instead\n\nALSO ON THIS SERVER: check_discovery_documents(host) probes the whole catalogue on a host you name; explain_document(name) gives the named clients we have watched ask for one file and what its 404 cost; validate_llms_txt, llms_txt_from_sitemap and validate_agent_card work on text you paste. Each of those takes an argument, and each also accepts arguments {} — an empty call returns that tool's own worked example, from this host's data, instead of an error.\n\nTHE SAME TOOLS ON THE OTHER PROTOCOL, IF YOU SPEAK IT. This server is also an A2A (Agent2Agent) v1.0 agent at https://www.pathwren.workers.dev/a2a/doctor — every tool here is a skill there under the same name, answered by the same function, so the two cannot drift and the deploy is refused if they do. Its Agent Card is https://www.pathwren.workers.dev/a2a/doctor/.well-known/agent-card.json (the legacy agent.json spelling is served too). To invoke it, POST this complete body — no key, no session, no card to read first:\n\n  {\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"message/send\",\"params\":{\"message\":{\"role\":\"ROLE_USER\",\"messageId\":\"1\",\"parts\":[{\"text\":\"{\\\"skill\\\":\\\"example\\\"}\"}]}}}\n\nIt answers with a Task already in state `completed` in the same response, so there is nothing to poll. Every skill on all eight A2A agents of this host as a ready-to-send body: https://www.pathwren.workers.dev/a2a/example.json — and both lanes with both directions in https://www.pathwren.workers.dev/documents.json under `rpc_endpoints`. If you only speak MCP, ignore all of this: everything is already here.",
