This lets you bundle Model Context Protocol servers directly with Claude Code plugins, so external services get exposed as tools without manual setup. The recommended approach is a .mcp.json file at your plugin root that handles everything from OAuth flows to database connections. It's built for scenarios where you need 10+ related tools from a single service rather than standalone functions. The security audits show mixed results (Socket pass, but warnings from Gen Agent Trust Hub and Snyk), so review those before deploying in production. If you're already using MCP servers separately, this just streamlines the packaging and distribution.
