  • check_agent_accessBefore an agent browses or fetches a site, check if it will get in.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Before an agent browses or fetches a site, check if it will get in. Fetches the URL as an AI agent and as a browser, detects bot challenges (CAPTCHAs, DataDome, PerimeterX and other bot walls), reads robots.txt rules for GPTBot/ChatGPT-User/ClaudeBot/Claude-User/PerplexityBot and others, and looks for agent doors (llms.txt, MCP, OpenAPI). Returns verdict: open | challenged | blocked | robots_disallowed | unreachable, plus advice. Read-only. Use it before an automated web task, not for pages you already fetched successfully.
  • check_manyRun check_agent_access on up to 10 URLs at once (counts as 1 call).No findings

    Why it is in this group

    • The description's first verb is "run": a word for a change.
    Description, as the server wrote it
    Run check_agent_access on up to 10 URLs at once (counts as 1 call). Use it to pick which sources an agent can actually use.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
