Claude Code MCP Server

Claude Code MCP Server

The Claude Code MCP Server is a robust implementation of the Model Context Protocol (MCP) that facilitates the execution of Claude Code in a one-shot mode while automatically bypassing permission restrictions. This innovative tool addresses common challenges faced by many users, particularly when performing smaller file edits—allowing seamless and efficient interactions with Claude Code.

Key Features

This MCP server offers powerful capabilities that enhance the functionality of LLMs (Large Language Models) when interacting with Claude Code, particularly when integrated with clients like Claude Desktop. The server allows:

• Execution of Claude Code without permission interruptions using --dangerously-skip-permissions.
• File editing capabilities directly integrated into the workflow.
• The ability to enable specific tools by default for improved efficiency.

Prerequisites

Before utilizing the server, ensure the following requirements are met:

• Node.js version 16 or later.
• TypeScript is installed for development purposes.
• The Claude CLI must be installed and operational. Verify the installation by running ./doctor, ensuring the CLI is accessible at ~/.claude/local/claude by default.

Connecting to Various Environments

macOS

For macOS users, configure the MCP by creating or modifying the MCP configuration file at:

~/.cursor/mcp.json

Add the following server configuration:

{
  "mcpServers": {
    "claude_code": {
      "type": "stdio",
      "command": "/absolute/path/to/claude-mcp-server/start.sh",
      "args": []
    }
  }
}

Windows

Windows users should locate the MCP configuration file at:

%APPDATA%\cursor\mcp.json

Add the equivalent server configuration ensuring to use Windows path formatting:

{
  "mcpServers": {
    "claude_code": {
      "type": "stdio",
      "command": "C:\path\to\claude-mcp-server\start.bat",
      "args": []
    }
  }
}

Linux

For Linux users, create or edit the MCP configuration file at:

~/.config/cursor/mcp.json

And include the server configuration:

{
  "mcpServers": {
    "claude_code": {
      "type": "stdio",
      "command": "/absolute/path/to/claude-mcp-server/start.sh",
      "args": []
    }
  }
}

Tools and Usage

The server provides two primary tools for users:

1. Claude Code Tool (code): Executes prompts directly via the Claude Code CLI with all permission checks bypassed. This tool can manage complex, multi-step tasks effectively.

   • Example Usage:

   {
     "tool_name": "code",
     "params": {
       "prompt": "Your prompt to Claude Code here",
       "options": {
         "tools": ["Bash", "Read", "Write"]
       }
     }
   }
   

2. Magic File Edit Tool (magic_file): This tool allows users to edit specified files based on natural language instructions, enhancing usability for complex modifications.

   • Example Usage:

   {
     "tool_name": "magic_file",
     "params": {
       "file_path": "/path/to/your/file.js",
       "instruction": "Refactor the processData function to use async/await instead of promises."
     }
   }
   

The server’s toolset is designed to execute detailed natural language prompts, enabling a range of functionalities from advanced code refactoring to comprehensive Git operations.
