Docker just got some massive upgrades

Docker released the Docker MCP toolkit, a production-grade implementation of Anthropic's Model Context Protocol that containerizes AI agent capabilities. The system uses three core components: a curated catalog of versioned MCP server images, a gateway that acts as a dynamic proxy managing container lifecycle and routing, and a toolkit for credential management and permissions. This architecture isolates agent tools in containers, providing reproducibility, security through policy enforcement, and composability by allowing multiple MCP servers to run side-by-side without dependency conflicts.
