Agent Passport System — Cryptographic Identity for AI Agents

A comprehensive cryptographic infrastructure for AI agents that goes well beyond basic identity. You get Ed25519 keypairs, passport issuance and verification, scoped delegations with spend limits, policy evaluation engines, and three-signature enforcement chains for every action. The 154 tools span coordination workflows (task briefs, evidence handoffs, deliverables), governance (Agora messaging, values attestation), commerce preflights, agent-to-agent comms, and reputation-gated authority. Ships with profiles from minimal to full, supports both stdio and SSE transports, and implements strict RFC 8785 JCS for cross-implementation interop. Reach for this when you need agents to prove who they are, what they're authorized to do, and maintain cryptographic accountability for their actions.
