此 MCP 可以做什么

Issues, lists, and verifies signed, hash-chained receipts documenting agent actions and their inputs and outputs.

issue_receipt
Mint a verifiable provenance receipt for an autonomous-agent action. Returns a signed (ed25519), content-hashed (SHA-256), server-timestamped receipt that is hash-chained to this agent's prior receipts (tamper-evident audit trail). Pass the raw inputs/outputs (we hash them — raw data is never stored) OR pre-computed sha256 hashes. Use for compliance, audit trails, and dispute resolution of agentic actions. PAID: $0.01 USDC/call via x402.
输入模式
{'type': 'object', 'required': ['action'], 'properties': {'action': {'type': 'string', 'description': "What the agent did, e.g. 'sent_payment' or 'approved_refund' or 'tool_call:search'."}, 'inputs': {'description': 'Raw inputs to the action (any JSON). Hashed to a commitment; raw data not stored.'}, 'outputs': {'description': 'Raw outputs/result of the action (any JSON). Hashed to a commitment; raw data not stored.'}, 'agent_id': {'type': 'string', 'description': 'Stable identifier for the acting agent (chains group by this).'}, 'metadata': {'type': 'object', 'description': 'Optional small key/value context (model, version, request id, etc.).'}, 'inputs_hash': {'type': 'string', 'description': "Alternatively, a pre-computed sha256 hex (or 'sha256:<hex>') of inputs."}, 'outputs_hash': {'type': 'string', 'description': "Alternatively, a pre-computed sha256 hex (or 'sha256:<hex>') of outputs."}}}
list_receipts
List the receipt hash-chain for an agent_id, newest first (id, action, timestamp, sequence, hashes, verifyUrl). Use to audit everything a given agent has attested. FREE.
输入模式
{'type': 'object', 'required': ['agent_id'], 'properties': {'limit': {'type': 'number', 'description': 'Max receipts (default 25, max 100).'}, 'agent_id': {'type': 'string', 'description': 'The agent whose receipts to list.'}}}
verify_receipt
Verify a receipt by id (or by passing the full receipt object). Recomputes the content hash, confirms the id commits to the body, and checks the ed25519 signature. Returns the verification checks plus the provenance record (action, agent, input/output hashes, timestamp, chain position). FREE.
输入模式
{'type': 'object', 'properties': {'id': {'type': 'string', 'description': "Receipt id, e.g. 'rcpt_...'."}, 'receipt': {'type': 'object', 'description': 'Alternatively, the full receipt object to verify offline-style.'}}}
