CodeCommander

You can use this MCP server to empower AI assistants with code intelligence, JSON repair, encoding fixes, import organization, format conversion, file comparison, and regex testing. It includes 17 developer-focused tools that work alongside FileCommander to enhance coding workflows across Windows, macOS, and Linux.

How to use

You run CodeCommander as an MCP server and connect your MCP client to it. You can use the server to analyze Python code, repair JSON, organize imports, fix encodings, convert between data formats, compare files, and test regular expressions. The tools are designed to be used from your development environment to automate routine code-quality tasks, improve JSON quality, and enable richer code intelligence during AI-assisted coding sessions.

How to install

PrPrerequisites: You need Node.js 18 or higher to run CodeCommander.

npm install -g bach-codecommander-mcp

Install from source by cloning the repository, installing dependencies, and building.

git clone https://github.com/lukisch/bach-codecommander-mcp.git
cd bach-codecommander-mcp
npm install
npm run build

Configuration details you will use

Connect CodeCommander to Claude Desktop by configuring MCP servers in your claude_desktop_config.json file.

{
  "mcpServers": {
    "codecommander": {
      "command": "bach-codecommander"
    }
  }
}

Using both FileCommander and CodeCommander together

You can run FileCommander and CodeCommander side by side by listing both MCP servers in your configuration. This enables JSON repair and code analysis workflows alongside file operations.

{
  "mcpServers": {
    "filecommander": {
      "command": "bach-filecommander"
    },
    "codecommander": {
      "command": "bach-codecommander"
    }
  }
}
