Docker

Wraps the Docker CLI to give Claude five container and image operations: list running or stopped containers with resource usage, list images with size and layer info, fetch container logs with filtering and tail support, and analyze both Dockerfiles and docker-compose.yml files for best practices like multi-stage builds, security issues, and layer caching. The analysis tools parse configuration content directly rather than running containers, so you can review files before building. Requires Node.js 18+ and Docker installed locally. Useful when you're debugging container issues in chat, auditing Dockerfiles for optimization opportunities, or need to check what's actually running without switching to the terminal.
