Uber details MCP Gateway for managing 800 servers and 5,000 tools

By PulseAugur Editorial · [1 sources] ·

Uber has detailed its MCP Gateway, a microservice designed to manage interactions with over 800 MCP servers and 5,000 tools. This system, published on October 1, 2026, features a registry control plane and a proxy data plane that translates MCP calls into various protocols. A key design principle is that all tools start disabled, requiring owner review and approval for enablement, thereby separating discovery from exposure. The system implements two layers of authorization: enablement and caller policy, but lacks a per-call judgment layer, which is identified as a critical area for future development. AI

IMPACT Provides insight into enterprise-grade microservice management and authorization for AI agents, highlighting challenges in discovery and per-call judgment.

RANK_REASON The item describes an internal system design and implementation for managing microservices and tools, which falls under infrastructure or tooling rather than a frontier release, significant industry event, or research paper.
