The AGNTCY protocol — a vendor-neutral standard for agent discovery, identity and inter-agent messaging — has reached 1.0, giving open source agent builders a stable target after a year of drafts.
What 1.0 standardizes
- ▸Agent identity and capability manifests
- ▸Authenticated agent-to-agent messaging with delegation chains
- ▸A discovery layer so agents can find and evaluate each other
Why standards matter here
Agent ecosystems are currently walled gardens: an agent built for one platform cannot hire, message or verify an agent on another. Interoperability determines whether the agent economy is open or captured.
Reference implementations in Python and TypeScript ship alongside the spec, with adapters for the major agent frameworks.
