AI Agent Identity Management Framework

Building Autonomous AI agents is getting easier with frameworks like LangChain and LangGraph
Knowing which agent did what, on whose authority, and with what permissions is still messy.

We’ve been working on ZeroID, an open-source identity layer for AI agents that gives every agent its own cryptographically verifiable identity, supports agent-to-agent delegation, and enables real-time revocation.

Why this matters for AI agent developers who want to run their autonomous agents in production:

  • No more shared service-account style access
  • Sub-agents get scoped, downscoped credentials
  • Every action can carry an auditable delegation chain
  • Better fit for MCP servers, tool-calling agents, and multi-agent workflows

Under the hood, ZeroID is built around OAuth 2.1, RFC 8693 token exchange, and WIMSE/SPIFFE-style identities.

If you’re building agentic systems and thinking about auth, delegation, trust, or audit-ability, do checkout:

cool project but zeroid already provides cryptographically signed audit trails for the identity that it generates.
