    Why it is in this group

    • The name "agent_payment_readiness_assessment" says "payment": a word that usually means money moves, which cannot be taken back.
    • 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
    Paid: $1.00 per call over the Machine Payments Protocol, or one prepaid SET Agent Credits call (Authorization: Bearer <key> on the MCP request). Classifies what you declare about ten capabilities of a payment workflow (discovery, payment challenge and receipt, idempotency, webhook verification, fulfillment, authentication, wallet ownership, on-ramp handoff, delivery evidence, recovery) and returns the blocking controls and the order to fix them. It verifies nothing independently and authorizes no payment.

Changes things 1Claude Code: ask
  • ai_visibility_checkPaid: $1.00 per call over the Machine Payments Protocol, or one prepaid SET Agent Credits call (Authorization: Bearer <key> on the MCP request).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
    Paid: $1.00 per call over the Machine Payments Protocol, or one prepaid SET Agent Credits call (Authorization: Bearer <key> on the MCP request). Audits one public page from public fetches only: which of 15 search and AI crawlers its robots.txt allows (each with the deciding rule and the vendor's documentation), its indexing and snippet directives, title, meta description, canonical, JSON-LD, Open Graph, lang, h1 and server-rendered text, plus site signals (redirects, HTTPS, time to first byte, sitemap, llms.txt, llms-full.txt). Returns a 0-100 readiness score against a published rubric and prioritized findings, each with what was observed, why it matters and the fix. It implies no ranking, traffic or citation outcome. The page is checked before payment is taken; a failed check is not charged.

  • list_paid_servicesFree.No findings

    Why it is in this group

    • The name "list_paid_services" says "list": a word for reading.
    Description, as the server wrote it
    Free. Lists SET's paid agent services, their prices, how to pay (Machine Payments Protocol or prepaid SET Agent Credits) and the HTTP endpoints behind each tool.

    Annotations the server declares

    • readOnlyHint: 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.
