+Docker Developer Tools is a Cursor IDE plugin that integrates Docker and container workflows into Cursor's AI chat. It includes 14 skills, 8 rules, and a companion MCP server with 68 tools for live Docker CLI integration.
 
 This is a monorepo - the Cursor plugin (skills and rules) and the companion MCP server live in the same repository. Docker's API is local (Docker Engine socket / CLI), so one repo is simpler for users to install and maintain.
