An Agent Auth directory is a searchable index of services that implement the Agent Auth protocol. It's part of the protocol's discovery mechanism — instead of hardcoding every service endpoint, agents can query a directory to find services by intent, capability, or domain.
A directory indexes servers that publish a /.well-known/agent-configuration endpoint. Agents describe what they need — "I need to send a bank transfer" or "I need calendar access" — and the directory returns matching services with their capabilities, endpoint URLs, and registration requirements.
Anyone can run their own directory. The protocol defines the interface, not the operator. Server operators can also register their endpoints on any public directory to make them discoverable by agents.
Public Directory
agent-auth.directory
We maintain a public, open directory where server operators can list their services and agents can discover them. Browse existing services or register your own.
