Uber details MCP Gateway managing 5,000+ tools for AI agents

By PulseAugur Editorial · [1 sources] ·

Uber has developed an MCP Gateway system to manage over 5,000 tools for AI agents, addressing the challenge of context window bloat. The system comprises an MCP Registry for cataloging and enablement, and a Proxy Gateway for runtime translation and execution, ensuring existing services remain untouched. This architecture allows agents to incrementally discover and invoke internal APIs without overwhelming the model's context window, using features like incremental discovery and response projection.
