InfoQ: Uber Builds MCP Gateway to Govern Access to 800+ Servers and 5,000+ AI Agent Tools
Uber built an MCP Gateway that separates a registry control plane from a proxy runtime to let AI agents discover and invoke internal services. The platform reportedly supports more than 800 MCP servers and 5,000 tools. It enforces authorization at server and tool levels, redacts PII in responses, and uses incremental discovery to limit context loading.
What changes for platform teams
Platform teams running many internal APIs can see a pattern for exposing existing services as MCP tools without changing the services, with new tools disabled until owners enable them. The approach relies on established API gateway concepts, so teams already running API gateways can reuse those governance ideas.
