ACPP
Give agents an identity, not just an API key.
Agent Communication per Protocol — identity, trust, signaling, and authorization infrastructure for AI agents.
What this is
ACPP is an identity and authorization layer for agents: verifiable identities, structured signals, deterministic policy, receipts, and connectivity (first connector: GitHub).
It is not a chatbot, MCP marketplace, or agent orchestration platform.
Status
Phase 0 / early Phase 1 scaffold. Community / self-host / open protocol first. No paid hosted pricing UI until an explicit product decision.
