  • check_domainsCheck domain name availability via public registry RDAP for .xyz .com .io .ai .app .dev, plus variations (get-, -hq, -labs, try-).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.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Check domain name availability via public registry RDAP for .xyz .com .io .ai .app .dev, plus variations (get-, -hq, -labs, try-). 404 from the registry = likely available. Not a registrar quote; confirm at checkout. PAID via x402: 0.005 USDC on Base per call; call without x_payment to get requirements.

  • read_urlFetch a public web page and return clean Markdown of its main content (title, byline, excerpt, markdown).No findings

    Why it is in this group

    • The name "read_url" says "read": a word for reading.
    Description, as the server wrote it
    Fetch a public web page and return clean Markdown of its main content (title, byline, excerpt, markdown). PAID via x402: 0.005 USDC on Base per successful call. Call without x_payment to get the exact x402 payment requirements; sign them with an x402 client (exact scheme, EIP-3009 USDC transferWithAuthorization) and call again with the base64 PAYMENT-SIGNATURE (v2) or X-PAYMENT (v1) value in x_payment. You are only charged if extraction succeeds.

    Annotations the server declares

    • title: Read URL as Markdown (x402, 0.005 USDC)
    • readOnlyHint: true
    • openWorldHint: true

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.
