Pull request overview
This PR adds a comprehensive MCP (Model Context Protocol) experiment that enables AI assistants like Claude Desktop, Cursor, and VS Code to interact with WordPress capabilities via the Model Context Protocol. The implementation includes a full-stack solution with PHP backend management, React-based admin UI, REST API endpoints, and extensive configuration options.
Key Changes:
- Full MCP server management system with multi-server support and configurable routes
- React-based admin dashboard with DataViews for managing exposed abilities and server configuration
- REST API controller for server CRUD operations, tool management, and connection testing
- Auto-generated client configuration templates for popular MCP clients
