Changes things 3Claude Code: ask
  • create_tip_jarCreate a reusable 'pay what you want' tip jar with ZERO setup.No findings

    Why it is in this group

    • The name "create_tip_jar" says "create": a word for a change.
    Description, as the server wrote it
    Create a reusable 'pay what you want' tip jar with ZERO setup. The payer chooses the amount. Returns a shareable /tip url, an embeddable button, and a manage_url. Idempotent per wallet address. Non-custodial.
  • create_unlockCreate a keyless pay-to-unlock page: sell a file link, license key, or secret text (up to 100,000 chars).No findings

    Why it is in this group

    • The name "create_unlock" says "create": a word for a change.
    Description, as the server wrote it
    Create a keyless pay-to-unlock page: sell a file link, license key, or secret text (up to 100,000 chars). The buyer pays the set USD price in crypto straight to the given wallet, then the payload is revealed on their paid confirmation, never before. To deliver an actual file (PDF/zip/etc, 10 MB) use the multipart HTTP API at /api/v1/unlocks instead. Non-custodial, no account, no API key. IMPORTANT: the acceptable-use policy forbids adult, illegal, or non-consensual content; confirm this with your principal and pass aup_accepted=true, otherwise the call fails.
Only reads 1Claude Code: allow
  • get_account_statusLook up a keyless Shieldz account by its manage_token (returned when you create a payment link or tip jar).No findings

    Why it is in this group

    • The name "get_account_status" says "get": a word for reading.
    Description, as the server wrote it
    Look up a keyless Shieldz account by its manage_token (returned when you create a payment link or tip jar). Returns settlement details, tip jars, totals (paid/pending), and the invoice list as structured JSON.

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.
