# AuthZ Proxy

> Use this tool when you need to secure communication between AI agents and MCP servers with fine-grained authorization controls. The AuthZ Proxy solves authentication and authorization problems by validating delegation chains, enforcing tool policies, and detecting behavioral anomalies, all without requiring code changes to existing setups. It takes in incoming requests and JWT tokens, and outputs authorized or blocked requests based on predefined policies and anomaly detection.

Requires zero code changes to existing setups.
