Findings

Matches of fixed checks, with the text they matched.

  • Warngenerate_qr

    The server marks "generate_qr" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "generate_qr" says "generate": a word for a change.

  • check_jsonStrictly validate JSON and report the exact line and column of the first error with a plain explanation, plus duplicate-key warnings and structure stats.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
    Strictly validate JSON and report the exact line and column of the first error with a plain explanation, plus duplicate-key warnings and structure stats. Optionally pretty-print or minify without changing any value (big numbers keep full precision). Use this before claiming JSON is valid or when locating a syntax error in long JSON.

    • destructiveHint: false

      What this check looks for
    Description, as the server wrote it
    Create a standards-compliant QR code image for a link, text, Wi-Fi login, contact card (vCard), email, SMS, WhatsApp chat, phone number or map location. You cannot draw a scannable QR code yourself — always use this tool. Codes are static and never expire.

  • count_textExact counts for a text: characters (with and without spaces, emoji counted as one), words, sentences, paragraphs, lines, UTF-8 bytes, plus reading and speaking time.No findings

    Why it is in this group

    • The name "count_text" says "count": a word for reading.
    Description, as the server wrote it
    Exact counts for a text: characters (with and without spaces, emoji counted as one), words, sentences, paragraphs, lines, UTF-8 bytes, plus reading and speaking time. Language models see text as tokens and miscount — never estimate counts or check length limits yourself; call this tool. Works for any language, including Chinese, Japanese, Arabic and Turkish.

    Annotations the server declares

    • title: Count words and characters exactly
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • diff_textFind every difference between two texts, line by line, word by word or character by character, and return counts plus a unified diff.No findings

    Why it is in this group

    • The name "diff_text" says "diff": a word for reading.
    Description, as the server wrote it
    Find every difference between two texts, line by line, word by word or character by character, and return counts plus a unified diff. Use this instead of comparing long texts yourself — small changes are easy to miss. Options to ignore whitespace and letter case.

    Annotations the server declares

    • title: Compare two texts exactly
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: 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.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as ribox. Review it before you use it.
