The Challenge

Key Pain Points:

•
Implementing complete MCP 2024-11-05 specification compliance across 145 tools
•
Architecting a modular system with 17 specialized API clients and 20+ independent modules
•
Building enterprise-grade security with multi-layer validation and protection against SQL injection, XSS, and CSRF
•
Handling large-scale WordPress operations with efficient pagination, caching, and batch processing
•
Ensuring 100% TypeScript type safety while maintaining spec compliance
•
Creating comprehensive test coverage for enterprise reliability

Business Impact

Without a proper MCP server for WordPress, developers waste time building custom integrations, AI systems can't reliably manage WordPress sites, and organizations face security risks from ad-hoc solutions. The lack of a reference implementation slows adoption of MCP across the WordPress ecosystem.
