classify_user_agent	Identify the crawler behind a raw User-Agent header: operator, category, robots.txt stance, how to verify it, and what blocking it costs. A user-agent is a claim, not proof — confirm with is_verified_crawler_ip. Example: user_agent='GPTBot/1.2' returns GPTBot, OpenAI, ai-training. Also callable without MCP, same implementation: GET https://www.pathwren.workers.dev/tools/classify-ua?ua=GPTBot%2F1.2&s=client-dossiers
lookup_crawler	The full index record for one crawler: operator, category, robots.txt token and stance, user-agent substring and example, verification method, mirrored IP-range endpoint, and what blocking it costs. An unknown slug returns near matches. Example: slug='claudebot'.
list_crawlers	The index, filtered or whole: each row says what the crawler is and what blocking it costs, and the reply lists every valid filter value. Example: category='ai-training', limit=20.
generate_robots_txt	A ready-to-paste robots.txt block for one stance, with the reasoning and the crawlers it names. Omit the argument to get all eight stances described. Example: stance='block-ai-training'.
is_verified_crawler_ip	Test an IPv4 or IPv6 address against every crawler prefix the operators themselves publish, remirrored every six hours. Returns the matching prefix, its source and the crawlers using it; a miss is reported as a miss, not as a forgery. Example: ip='20.171.206.5'. Also callable without MCP, same implementation: GET https://www.pathwren.workers.dev/tools/verify-crawler?ip=20.171.206.5&s=client-dossiers
whats_changed	Freshness and change state: when the index was built, when each operator source was last fetched, which changed, which are failing, and the dated changelog. The cron check before regenerating a config from this data. Example: since='2026-08-01'.
changes_since	Only what changed since your last call: prefixes added or removed, upstreams failed or recovered, records edited. Send back the `cursor` from the previous result; it advances only on a real change, and the data refreshes every 6h. Example: since='0'.
whoami	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 came from, the class this host's own instrument books you as, whether we have seen you here before and what you fetched, and what the crawler index makes of the user-agent you sent, and whether the address you came from is inside a prefix its operator publishes — both run through this server's own classify_user_agent and is_verified_crawler_ip, on the same data a stranger can curl. Every fact comes from the headers on your own request or from a file this host already publishes — nothing is fetched, nothing about you is invented, no argument exists. Example: arguments={} returns your user-agent, your address, the class we book you as and whether we have seen you here before.
example	Takes no arguments. Safe to call. Deterministic. Touches no third party. Runs this server's own worked example end to end — classify_user_agent on the exact user-agent string of the busiest client in this host's own published log (/data/observed-clients.json, 1164 requests in the window) — our data, and no third party is asked anything — 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 classify_user_agent with {"user_agent":"Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1. and returns its real answer.
