About HARP
An open protocol ensuring every AI agent action receives explicit human authorization.
What is HARP?
Section titled “What is HARP?”HARP (Human Authorization & Review Protocol) is an open, cryptographically verifiable protocol that ensures every AI agent action receives explicit human approval before execution.
As AI coding agents become increasingly autonomous — generating plans, modifying files, running commands, and deploying code — HARP provides the missing authorization layer: a secure, out-of-band mechanism for humans to review and cryptographically sign every action.
Design principles
Section titled “Design principles”- Open standard — HARP is a protocol specification, not a product. Anyone can implement it.
- Zero-knowledge — The relay infrastructure never sees plaintext code or diffs.
- Fail-closed — If verification fails for any reason, execution is denied.
- Interoperable — Works with any AI agent, IDE, or mobile platform.
