    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
    Full due-diligence report for one domain: registration age/expiry/status (live RDAP), backlinks & authority from our own Common Crawl link graph, toxic-linker audit, website history (Wayback), trademark search links, and optional blacklist when configured. Use before buying a domain. No composite appraisal score — flags + per-section detail only.

    • The description's first verb is "generate": a word for a change.

      What this check looks for
    Description, as the server wrote it
    Generate brandable .com domain names for a business idea and return ONLY the ones that are currently AVAILABLE to register (checked against the Verisign RDAP registry through a caching proxy; an available answer can be up to 10 minutes old). Give a keyword and, ideally, a short description of the business for better names.

    Why it is in this group

    • The name "find_available_domains_by_pattern" says "find": a word for reading.
    Description, as the server wrote it
    Exhaustively enumerate EVERY available domain matching a keyword PATTERN, across TLDs — the thing most domain tools/MCPs can't do. Give a keyword (or several) and a position: 'starts' (keyword+word, e.g. Bearoak), 'ends' (word+keyword, e.g. Oakbear), 'contains' (keyword inside a longer invented word, e.g. Oakbearen), or 'all'. Every candidate is checked against the registry (cached answers up to 10 minutes old); only AVAILABLE domains are returned, grouped by TLD. Checks .com and .net by default.

    Annotations the server declares

    • title: List available domains by keyword pattern
    • readOnlyHint: true
    • destructiveHint: false
    • 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.
