MCP gateway

In short: An MCP gateway sits between agents and MCP servers so every tool call passes through it. It identifies the agent and the person behind it, applies policy, filters tools and supplies credentials. It gives one enforcement point across many servers, including ones you did not build.

Where does it show up in practice?

Silverfort, Aembit and NewCore all describe gateways in the path of MCP calls.
