Code Intelligence MCP

English | 中文

Intelligent code suggestion MCP service that provides AI-powered component and utility method recommendations for AI IDEs.

Introduction

This is an intelligent code suggestion service based on Model Context Protocol (MCP). It analyzes user requirements through AI and recommends the most suitable components and utility methods from private code repositories, helping developers improve code reuse and development efficiency.

Core Capabilities

🎨 UI Component Intelligent Recommendation

• Analyze UI development requirements (pages, forms, interfaces, etc.)
• Match the most relevant private components from the knowledge base
• Generate optimized prompts with component imports and usage
• Provide complete implementation guides and code examples

🔧 Utility Method Intelligent Recommendation

• Analyze logic function requirements (data processing, format conversion, utility functions, etc.)
• Find reusable utility methods from the method knowledge base
• Generate optimized prompts with method imports and invocation
• Avoid reinventing the wheel and improve code quality

Features

Intelligent Analysis Engine

• Requirement Understanding: Deep understanding of user development intentions based on AI
• Keyword Extraction: Automatically identify core elements in requirements
• Complexity Assessment: Intelligently evaluate implementation difficulty and component fit

Knowledge Base Management

• Component Knowledge Base: Manage private UI component library (props, events, slots, examples)
• Method Knowledge Base: Manage utility method library (parameters, return values, types, usage)
• Relevance Algorithm: Calculate recommendation scores based on semantic matching

Prompt Optimization

• Bidirectional Optimization: Support prompt redesign for both component and method scenarios
• Structured Output: Generate complete solutions including import statements and implementation steps
• Best Practices: Integrate code standards and usage recommendations

Installation and Usage

Method 1: Use with npx (Recommended)

This is the recommended way for using the MCP server with AI IDEs like Claude Desktop.

Step 1: Prepare Configuration Files

Create a configuration directory (recommended location: ~/.config/ci-mcp):

mkdir -p ~/.config/ci-mcp

Download or create the following three configuration files:

1. config.json - AI model configuration
2. components.json - UI component knowledge base
3. utils.json - Utility method knowledge base

You can find example files in the npm package or repository.

Step 2: Configure AI IDE

Add to your AI IDE configuration (e.g., Claude Desktop's claude_desktop_config.json):

{
  "mcpServers": {
    "code-intelligence": {
      "command": "npx",
      "args": ["-y", "code-intelligence-mcp"],
      "env": {
        "CI_MCP_DATA_DIR": "~/.config/ci-mcp"
      }
    }
  }
}

Environment Variables:

• CI_MCP_DATA_DIR (Recommended): Specify the configuration directory, all three files will be loaded from this directory
• CI_MCP_CONFIG: Directly specify the path to config.json
• CI_MCP_COMPONENTS: Directly specify the path to components.json
• CI_MCP_UTILS: Directly specify the path to utils.json

Path Formats Supported:

• Absolute path: /Users/xxx/.config/ci-mcp
• Home directory: ~/.config/ci-mcp or $HOME/.config/ci-mcp
• Environment variables: ${MY_CONFIG_DIR}/ci-mcp

Step 3: Restart AI IDE

Restart your AI IDE (e.g., Claude Desktop), and the MCP service will start automatically via npx.

Method 2: Local Development

Prerequisites

Configure Knowledge Base Data Files

The project requires manual configuration of the following data files in ci-mcp-data/ directory:

1. ci-mcp-data/config.json - AI model configuration (including API Key)

   cp ci-mcp-data/config.example.json ci-mcp-data/config.json
   # Edit config.json and fill in your API Key

2. ci-mcp-data/components.json - UI component knowledge base

   cp ci-mcp-data/components.example.json ci-mcp-data/components.json
   # Edit components.json based on your private component library

   • Add component information following the existing format: description, import, relativePath, etc.

3. ci-mcp-data/utils.json - Utility method knowledge base

   cp ci-mcp-data/utils.example.json ci-mcp-data/utils.json
   # Edit utils.json based on your utility method library

   • Include method information: description, import, params, returns, etc.

Note:

• config.json contains sensitive information (API Key) and is added to .gitignore, will not be committed to the repository
• components.json and utils.json need to be configured based on your actual code repository
• Refer to example files like config.example.json for configuration format
