Docker Command Runner MCP Server

MCP server (v1.0.0) that executes commands inside Docker containers via Model Context Protocol. Provides a single `run_command` tool for running arbitrary commands in allowed Docker Compose service containers. Uses STDIO transport, supports container allowlisting via environment variables, configurable timeouts, and captures stdout/stderr. Minimal dependencies, ships TypeScript types. Released under MIT license. Key differentiator: purpose-built for MCP (Claude) integration rather than generic Docker exec wrappers. Requires Docker socket access and security relies on container isolation.
