Code Explainer MCP

🚀 Code Explainer MCP Working Principle Explanation

This is a Cloudflare Worker, serving as a Model Context Protocol (MCP) server for code explanation. It provides a comprehensive breakdown of the structure and functionality by analyzing and interpreting code.

✨ Features

• Architecture Diagram Generation: Create ASCII diagrams to illustrate the overall structure, relationships between components, and data flow.
• Core Function Analysis: Determine and explain the main purpose of the code through pattern recognition.
• Component Decomposition: List all major classes and functions and briefly describe their roles.
• Multi - language Support: Support multiple programming languages, including JavaScript, TypeScript, Python, Java, C#, etc.
• Documentation Comment Recognition: Extract and utilize existing documentation comments in the code (e.g., JSDoc or Docstring).
• Secure API: Use Bearer tokens for authentication to ensure the security of endpoints.

🔧 Technical Details

The code explainer analyzes the source code through the following steps:

1. Pattern Recognition: Identify common structures and design patterns in the code.
2. Architecture Decomposition: Parse the hierarchical structure of the code to determine the main components and their interactions.
3. Function Description: Describe in detail the roles and interactions of each function, class, and module.
4. Documentation Generation: Automatically generate easy - to - understand technical documentation for easy comprehension and maintenance.

💡 Development Guidelines

• Follow TypeScript best practices.
• Add comments to complex logic.
• Update the change log for public APIs.
• Add test cases for new features.

⚠️ Important Note

• Use Bearer tokens for authentication.
• Store shared keys using environment variables in the production environment.
• Do not commit actual keys to the version control system.
• It is recommended to implement rate limiting in the production environment.
