Records and audits an append-only, signed, on-chain-verifiable log of what agents did.

About

three.ws Provenance is an MCP server that keeps an append-only, cryptographically signed, on-chain-verifiable log of agent actions so you can record and audit exactly what an agent did. A solo builder running autonomous agents uses it for accountability and compliance, optionally ERC-191-signing each action so anyone can recover the signer and verify authorship on-chain.
