A2A Agent (Python)

See the Applications overview for prerequisites, configuration endpoints, and available scopes.

The Agent-to-Agent (A2A) protocol defines how AI agents discover and communicate with each other. An A2A agent secured with Vouch requires bearer token authentication – the Agent Card advertises the Vouch OIDC security scheme, and the agent validates access tokens against the Vouch JWKS endpoint.
