Basic information
Gives AI agents verifiable, tamper-evident receipts for their actions — attest_action signs a cryptographic receipt for what the agent did (email sent, payment made, form filed), verify_receipt checks it offline, get_identity returns the agent's did:key. Sign locally, verify anyw

Actionproof is an MCP server that enables AI agents to generate verifiable, tamper-evident cryptographic receipts for actions they perform. It provides tools to sign receipts for actions like sending emails, making payments, or filing forms, and to verify these receipts offline. It is intended for developers building trust and auditability into autonomous agent workflows.
Use the attest_action tool to sign a cryptographic receipt for an agent's action (e.g., email sent, payment made). Use verify_receipt to check the receipt offline. Use get_identity to return the agent's DID key. The server works locally; no backend is required.
attest_actionverify_receiptget_identity (DID key)It signs a cryptographic receipt for an action the agent performed, such as sending an email or making a payment.
It checks the receipt offline to confirm its authenticity and tamper evidence.
It returns the agent's DID key (did:key).
No, it operates entirely locally — sign locally, verify anywhere, zero backend.
Actions such as email sent, payment made, or form filed.
