Receipt-based verification for AI agent workflows — create, verify, and poll ephemeral proof objects
01Tools · 4
How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.
| Tool | Risk | Side effects | Approval |
|---|---|---|---|
| verify_receipt Verify a ProofSlip receipt and retrieve its full data (type, status, summary, payload, ref, expiry). Use this to check what happened before deciding what to do next. Returns the complete receipt if valid, or a not_found error if expired or missing. No API key required. | read | false | unknown |
| signup Get a free ProofSlip API key. Returns the key directly — save it immediately, it cannot be retrieved later. Only needed once. After signup, configure the key as PROOFSLIP_API_KEY environment variable to use create_receipt. Free tier: 500 receipts per month. | read | false | unknown |
| check_receipt_status Lightweight status poll for a ProofSlip receipt. Returns only status, is_terminal, and next_poll_after_seconds — no payload or summary. Use this instead of verify_receipt when you only need to know if a receipt state has changed. If is_terminal is false, wait next_poll_after_seconds before checking again. No API key required. | read | false | unknown |
| create_receipt Create a ProofSlip receipt to record that something happened. Use 'action' for completed events, 'approval' for decisions awaiting review, 'handshake' for agent-to-agent coordination, 'resume' for continuation bookmarks, 'failure' for structured error records. Returns a receipt_id and verify_url. Receipts expire after 24 hours by default. | write | true | unknown |

This is one server. A loadout combines the right servers, governance, and proven plays for a whole job — assembled deliberately, not tool-dumped.
