MCP implementation of Claude Code capabilities

MCP Claude Code

An implementation of Claude Code capabilities using the Model Context Protocol (MCP).

Overview

This project provides an MCP server that implements Claude Code-like functionality, allowing Claude to directly execute instructions for modifying and improving project files. By leveraging the Model Context Protocol, this implementation enables seamless integration with various MCP clients including Claude Desktop.

Features

• Code Understanding: Analyze and understand codebases through file access and pattern searching
• Code Modification: Make targeted edits to files with proper permission handling
• Enhanced Command Execution: Run commands and scripts in various languages with improved error handling and shell support
• File Operations: Manage files with proper security controls through shell commands
• Code Discovery: Find relevant files and code patterns across your project
• Project Analysis: Understand project structure, dependencies, and frameworks

Getting Started

Usage

Configuring Claude Desktop

You can run it with uvx run mcp-claude-code without installation. Configure Claude Desktop to use this server by adding the following to your Claude Desktop configuration file:

{
  "mcpServers": {
    "claude-code": {
      "command": "uvx",
      "args": [
        "--from",
        "mcp-claude-code",
        "claudecode",
        "--allow-path",
        "/path/to/your/project"
      ]
    }
  }
}

Make sure to replace /path/to/your/project with the actual path to the project you want Claude to access.

Advanced Configuration Options

You can customize the server using other options:你

{
  "mcpServers": {
    "claude-code": {
      "command": "uvx",
      "args": [
        "--from",
        "mcp-claude-code",
        "claudecode",
        "--allow-path",
        "/path/to/project",
        "--name",
        "custom-claude-code",
        "--transport",
        "stdio"
      ]
    }
  }
}

Configuring Claude Desktop System Prompt

To get the best experience with Claude Code, you need to add the provided system prompt to your Claude Desktop client. This system prompt guides Claude through a structured workflow for code modifications and project management.

Follow these steps:

1. Locate the system prompt file in this repository at doc/system_prompt.md
2. Open your Claude Desktop client settings
3. Navigate to the system prompt configuration section
4. Copy the contents of system_prompt.md into your Claude Desktop system prompt
5. Replace {{project_path}} with the actual path to your project

The system prompt provides Claude with:

• A structured workflow for analyzing and modifying code
• Best practices for project exploration and analysis
• Guidelines for development, refactoring, and quality assurance
• Special formatting instructions for mathematical content

This step is crucial as it enables Claude to follow a consistent approach when helping you with code modifications.

Security

This implementation follows best practices for securing access to your filesystem:

• Permission prompts for file modifications and command execution
• Restricted access to specified directories only
• Input validation and sanitization
• Proper error handling and reporting

Development

To contribute to this project:

1. Fork the repository
2. Create a feature branch (git checkout -b feature/amazing-feature)
3. Commit your changes (git commit -m 'Add some amazing feature')
4. Push to the branch (git push origin feature/amazing-feature)
5. Open a Pull Request
