Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 561 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name notworking.

  • Pass
    Lists tools

    tools/list returned 2 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 561 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 561 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    8 of 8 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-16T02:58:28.72232Z, within 180 days.

check_status

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.

report

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.
