Hello Apigee Community! 
In our latest TechTalk, Nigel Walters (Apigee Customer Engineer) explores how to position Apigee as a centralized governance layer for Gemini Enterprise. He demonstrates how to treat MCP traffic as first-class API traffic, leveraging Apigee to govern tool exposure, enforce quotas, and provide a unified view of your agentic infrastructure.

The Agentic Control Layer 
To securely manage and scale AI agents, your architecture needs to leverage the gateway as an intelligent intermediary. Nigel highlighted three core architectural pillars:
-
Centralized MCP Governance: Using Apigee as an MCP proxy to unify authentication, authorization, and observability for all agentic tool invocations.
Google for Developers Content Guidance (go/gfd-guidelines) -
Productizing AI Tools: Leveraging Apigee API Products and new “Payload Operations” to define granular visibility into which MCP tools are available to specific agents.

Unified Enterprise Context: Connecting Gemini Enterprise apps to Apigee-hosted MCP servers, ensuring agents operate within a curated and secure enterprise environment.

Key Takeaways from the Session 
Nigel provided a technical deep dive into making AI integrations enterprise-ready.
He showcased how to propagate end-user identity through the entire chain—from the agent, to the MCP server, and down to the backend API—all without exposing sensitive ID tokens directly to the agent runtime. By using Apigee to transcode between JSON-RPC (MCP) and REST (backend APIs), organizations can enforce tool filtering and authorization (FGA) policies before requests reach the backend. Finally, Nigel demonstrated how API Hub helps catalog these MCP assets, providing a single source of truth to prevent “tool sprawl” across business units.
