Code Explainer

🚀 Code Explainer MCP

A Cloudflare Worker serving as an MCP (Model Context Protocol) server for code explanation. It analyzes and elaborately explains code, offering a comprehensive breakdown of its structure and functionality.

🚀 Quick Start

The Code Explainer MCP is a powerful tool for analyzing and explaining code. To get started, follow the installation and configuration steps below, and you'll be able to analyze code in no time.

✨ Features

• Architecture Diagram Generation: Generate ASCII diagrams to show 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 the main classes and functions and briefly describe their roles.
• Multi-language Support: Analyze code in multiple programming languages, including JavaScript, TypeScript, Python, Java, C#, etc.
• Documentation Comment Recognition: Extract and utilize JSDoc or docstrings in the code.
• Secure API: Use Bearer tokens for authentication to ensure the security of endpoints.

🔧 Technical Details

The code explainer analyzes source code through the following steps:

1. Pattern Recognition: Identify code structures and common patterns.
2. Relationship Analysis: Map the dependencies between components.
3. Documentation Extraction: Prioritize the use of existing comment documentation.
4. Architecture Visualization: Create an ASCII diagram of the code structure.
5. Component Explanation: Decompose and explain the main classes and functions.

💻 Usage Examples

Sending Request Format

Send a POST request with the following structure to analyze code:

{
  "method": "explainCode",
  "params": ["Code to be explained", "Programming language"]
}

Authorization Header Information

Add the following to the HTTP header:

• Content-Type: application/json
• Authorization: Bearer YOUR_SECRET_KEY_HERE

Local Development

• Start the development server:

  wrangler dev
  

• Test the endpoint:

  curl -X POST http://localhost:8787 \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer YOUR_SECRET_KEY_HERE" \
    -d '{"method":"explainCode","params":["function hello() { return \"Hello World\"; }","javascript"]}'

Security Precautions

⚠️ Important Note

• Use Bearer tokens for authentication.
• Store shared keys using environment variables in a production environment.
• Avoid committing actual keys to the version control system.
• It is recommended to enable rate limiting in a production environment.
