## Summary

The A2A Agent Card Policy rewrites the URL in the A2A Agent Card responses so that the exposed URL
points to the public endpoint of the Flex Gateway A2A server instance rather than directly to
backend services. This ensures that all client requests are routed through Flex Gateway, enabling it
to enforce security and access controls, while preventing direct access to backend resources.

The A2A Agent Card policy also enables the **Total Agent Calls** metric that tracks the total
successful and unsuccessful calls made to the agent. To view **Total Agent Calls**, see
[Viewing Key Metrics in API Manager for Managed Flex Gateway](https://docs.mulesoft.com/gateway/1.12/flex-managed-view-api-metrics).
