MoLing MCP server for AI agents

The MoLing MCP Server is a dependency-free office automation assistant that implements system interactions through operating system APIs. It enables file operations, command execution, and browser control without requiring additional software installations.

Installation Options

Using Installation Script

For Linux/macOS users, you can install MoLing via a shell script:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/gojue/moling/HEAD/install/install.sh)"

For Windows users (note: Windows compatibility may be limited):

powershell -ExecutionPolicy ByPass -c "irm https://raw.githubusercontent.com/gojue/moling/HEAD/install/install.ps1 | iex"

Manual Installation

Download the latest package from the releases page at GitHub
Extract the downloaded package
Run the server:

./moling

Building from Source

If you prefer to build from source (requires Golang):

git clone https://github.com/gojue/moling.git
cd moling
make build
./bin/moling

Configuration

Initial Setup

MoLing will create a configuration file at ~/.moling/config/config.json. You can initialize this file by running:

moling config --init

Configuring MCP Clients

Automatic Configuration

The easiest way to configure your MCP clients is to run:

moling client --install

This will automatically detect and configure compatible MCP clients on your system.

Manual Client Configuration

For Claude, add the following to the configuration file at ~/Library/Application\ Support/Claude/claude_desktop_config:

{
  "mcpServers": {
    "MoLing": {
      "command": "/usr/local/bin/moling",
      "args": []
    }
  }
}

Replace /usr/local/bin/moling with the actual path to your MoLing binary.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "MoLing" '{"command":"/usr/local/bin/moling","args":[]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "MoLing": {
            "command": "/usr/local/bin/moling",
            "args": []
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
