      What this check looks for
    Description, as the server wrote it
    Report that an access path failed for you. Use the access-path id from check_status, or the URL you used. Only report failures that came from the service, not ones caused by your own tools, permissions or settings (like a fetch tool that refuses a domain). Anonymous. Never include personal data, booking details, credentials or full URLs with query strings. target is which access path failed; what_failed is how, from this list (the same for every service): site_unreachable: The site or server could not be reached at all, for example a DNS error, a timeout or a 5xx server error.; bot_block: The service refused the agent: an access-denied page, a 403 or 429 error, a bot wall or a challenge page.; robots_disallow: The site's robots.txt asks automated agents not to fetch this page.; captcha: A CAPTCHA or 'are you human?' check stopped the agent.; login_auth: Logging in or authenticating failed, for example a login loop, a new login step or rejected credentials.; api_error: An API the agent used returned an error or an unexpected response.; mcp_error: An MCP server failed to connect, initialise, list its tools or run a tool.; skill_failed: A skill could not be installed, or it ran but errored or produced a wrong result.; payment: A payment or checkout step failed or was blocked.; specific_page: One particular page or step failed while the rest of the service seemed to work.; other: Something else went wrong.

    Why it is in this group

    • The name "check_status" says "status": a word for reading.
    Description, as the server wrote it
    Is it down or blocking agents for everyone, or just you? Use when a site, URL, MCP server or skill isn't working: down, unreachable or an outage, a timeout, blocked (access denied, 403, 429 rate limited, a Cloudflare 'Just a moment' challenge, a CAPTCHA), a login loop, an MCP server that won't connect or a tool that errors, or a skill that fails. Look up a service by the URL you used, an access-path id (clawhub:<owner>/<slug>, skills.sh:<owner>/<repo>/<skill>, an MCP Registry name like io.github.<owner>/<server>) or a service name. Returns a one-sentence summary, the service, every listed access path with a description and failure reports from the last hour (and the last 24 hours and 7 days as context), the what_failed values and how to report. Unlisted targets return their own counts and status, with listed: false.

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.
