Changes things 2Claude Code: ask
  • geo_auditAudits how visible one web page is to AI search engines and AI assistants: which of the major AI crawlers robots.txt allows or blocks, llms.txt and llms-full.txt presence, sitemap,…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
    Audits how visible one web page is to AI search engines and AI assistants: which of the major AI crawlers robots.txt allows or blocks, llms.txt and llms-full.txt presence, sitemap, and on-page signals (title, meta, canonical, structured data, headings, content readable without JavaScript). Returns a 0-100 score, grade and prioritised recommendations. Use it to check or monitor a site for generative-engine optimisation. Price: $0.02 per call, paid with x402.

    Annotations the server declares

    • title: AI visibility (GEO) audit for one URL

    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
    Checks whether a domain publishes /llms.txt and /llms-full.txt and validates llms.txt against the llmstxt.org structure: single H1 title, blockquote summary, H2 sections with markdown link lists, soft-404 detection and size. Respects robots.txt. Use it before or after publishing an llms.txt file. Price: $0.005 per call, paid with x402.

    Annotations the server declares

    Why it is in this group

    • The description's first verb is "read": a word for reading.
    Description, as the server wrote it
    Reads a domain's robots.txt (RFC 9309 matching) and reports, for each known AI crawler and AI agent (OpenAI, Anthropic, Google, Perplexity, Apple, Meta, Amazon, Common Crawl and others), whether it may fetch the site root and up to five extra paths, with the deciding rule and any Content-Signal preferences. Use it to see whether a site is open to AI search but closed to AI training. Price: $0.01 per call, paid with x402.

    Annotations the server declares

    • title: AI crawler access matrix from robots.txt
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true
  • india_id_validateValidates and decodes one Indian business or payment identifier offline: GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID and vehicle registration numbers.No findings

    Why it is in this group

    • The name "india_id_validate" says "validate": a word for reading.
    Description, as the server wrote it
    Validates and decodes one Indian business or payment identifier offline: GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID and vehicle registration numbers. Detects the type automatically, normalises copy-paste noise, verifies check digits where the algorithm is public (GSTIN), and decodes embedded fields such as state, PAN holder type or company type. Aadhaar numbers are refused. Use it to clean or pre-check form and invoice data. Price: $0.005 per call, paid with x402.

    Annotations the server declares

    • title: Validate and decode one Indian identifier
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false

    Why it is in this group

    • The name "india_id_validate_batch" says "validate": a word for reading.
    Description, as the server wrote it
    Batch version of the Indian identifier validator: up to 50 values per call (GSTIN, PAN, TAN, CIN, LLPIN, IFSC, PIN code, UPI ID and vehicle registration numbers), mixed types allowed, one flat price. Returns one decoded result per item plus counts by type and validity. Use it for cleaning vendor lists, invoices or onboarding data. Batches containing Aadhaar-like numbers are rejected without charge. Price: $0.02 per call, paid with x402.

    Annotations the server declares

    • title: Validate up to 50 Indian identifiers
    • 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.
