What is MCP?

The Model Context Protocol (MCP) is an open standard developed by Anthropic that enables AI applications (like Claude) to connect with external tools, data sources, and APIs in a standardized way. Think of it as “USB-C for AI applications” - it provides a universal connector between AI models and external systems.

Features

✨ Quick Setup: Generate production-ready MCP servers in minutes, not hours
🔧 Multiple Backends: Support for databases, APIs, filesystems, web scrapers, email, and cloud storage
🎯 Interactive Wizard: Guided setup with intelligent configuration prompts
📚 Comprehensive Templates: Pre-built templates following MCP best practices
🔒 Security First: Built-in security features and input validation
🧪 Testing Ready: Generated projects include test suites and examples
📖 Auto Documentation: Comprehensive documentation generation
🎨 Claude Desktop Integration: Automatic configuration for Claude Desktop
✅ Production Ready: Generates syntactically correct, tested code that works out of the box

Recent Improvements

🔧 Fixed Code Generation: Resolved indentation and syntax issues in generated MCP servers
📋 Corrected MCP Schema: Updated to use proper input_schema format
🧪 Improved Tests: Updated test templates to use modern MCP patterns
🔗 Fixed Resource URIs: Simplified resource implementations to avoid template issues
✨ Enhanced Reliability: All backend types now generate working, compilable code
