    Why it is in this group

    • The name "nexez_validate_negotiation" says "validate": a word for reading.
    • The description's first verb is "evaluate": a word for a change.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

      What this check looks for
    Description, as the server wrote it
    Evaluate proposed terms against an exact offer and the seller's published rules in a forced dry run. Returns rules-evaluation JSON text or validation errors. Inspect the offer first and supply its required terms. Never submits a proposal, contacts a seller, or writes a negotiation.

    • The description's first verb is "browse": a word for reading.
    Description, as the server wrote it
    Browse published Nexez listings without requiring a buyer query. All filters are optional. Returns directory JSON text with listing summaries and readiness information. Use nexez_search when you need ranked matches for a specific buyer request.

    Why it is in this group

    • The name "nexez_get_page" says "get": a word for reading.
    Description, as the server wrote it
    Fetch one listing's structured agent manifest as JSON text, including seller profile, offers, configuration requirements, and published actions. Use a slug returned by search or directory; inspect exact offer identifiers and requirements before validation.

    Annotations the server declares

    • title: Inspect a Nexez listing
    • readOnlyHint: true

    Why it is in this group

    • The name "nexez_validate_checkout" says "validate": a word for reading.
    Description, as the server wrote it
    Dry-run checkout for an exact published offer. Returns validation JSON text with offer readiness or errors and missing requirements. Inspect the offer with nexez_get_page first. Never charges or creates an order; a successful check is not a completed purchase.

    Annotations the server declares

    • 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.
