opena2a-org/agent-identity-management

Based on the README, here's a technical summary: Provides Ed25519 cryptographic identities with append-only audit logs and 8-factor trust scoring—deployable locally (file-based) or server-side (PostgreSQL-backed). Features fine-grained authorization via a 5-step pipeline (capability, attribute, context, delegation chain, intent checks), capability-scoped policies defined in YAML or REST API, and delegation chains with cryptographic scope narrowing and trust attenuation. Integrates with MCP servers through multi-agent consensus attestation and offers both CLI tooling and a dashboard for fleet governance across distributed agent ecosystems.
