Latest change
Uber built an MCP Gateway to govern agent access to more than 800 MCP servers and 5,000 tools, separating tool registration from runtime execution.
Earlier contextThe story so far
On Nov 1 a benchmark post reported a 17-point gap between agents running the same model across 21 MCP servers, putting the client side of MCP under scrutiny. On Nov 2 a Show HN project proposed cryptographic identity for agents calling MCP servers.

What to watch — open questions
- Will other large engineering orgs publish MCP gateway designs for discovery, auth and auditing?
- Will the 17-point agent-client gap be reproduced on other MCP server sets?
