Docker open-sources an MCP Gateway
Docker announced an open-source MCP Gateway intended to sit between AI agents and multiple MCP servers. The company described the gateway as a centralized enforcement point that works with Docker Compose and can apply options such as signature verification, call logging, and secret blocking. Docker said the gateway was available in Docker Desktop and as an open-source project for community use.

Engineering relevance
MCP connections create a growing tool and data-access boundary that benefits from centralized policy enforcement. Gateway features can support defense in depth, but they do not prove that a call is appropriate or that a server is trustworthy. An effective control plane also needs explicit allowlists, scope review, audit retention, and human accountability for high-impact actions.
Central enforcement point
Docker described the MCP Gateway as an aggregation layer for multiple MCP servers and an enforcement point between agents and external tools. The announcement linked the project to Docker Compose so developers could package agent workloads and their tool connections together. It emphasized moving from local experimentation toward governed environments.
Named controls
The release gave examples of startup options for signature verification, call logging, and scanning inbound and outbound payloads for material that resembles secrets. These options illustrate the type of controls a gateway can expose. They do not guarantee coverage for every protocol behavior, payload, tool action, or downstream system.
