Uber details a governed MCP gateway for more than 800 servers and 5,000 tools

Uber's engineering report describes automated API discovery, a registry and proxy, owner approval before tools are enabled, and on-demand discovery to reduce tool-context load. The scale figures are Uber-reported. This is an internal production architecture, not a downloadable gateway launch; later coverage does not reset its October 1 publication date.
