Script Tool MCP server for AI agents

Script Tool is a command-line utility that enables safe execution of scripts through Model Context Protocol (MCP). It provides a secure way to run command-line scripts with features like different interpreter support, timeout protection, output capture, and cross-platform compatibility across Linux, macOS, and Windows.

Installation

You can install the Script Tool using one of the following methods:

Download from GitHub Releases

Visit the GitHub Releases page
Download the binary for your platform:
- script-mcp_linux_amd64 for Linux
- script-mcp_darwin_amd64 for macOS
- script-mcp_windows_amd64.exe for Windows
Make the binary executable (Linux/macOS):
```
chmod +x script-mcp_*
```

Move it to your PATH (Linux/macOS):

sudo mv script-mcp_* /usr/local/bin/script-mcp@latest

Install with Go

If you have Go installed, you can install the tool directly using:

go install github.com/nguyenvanduocit/script-mcp

Configuration

Claude Configuration

To configure Script Tool as an MCP server for Claude, add the following to your Claude configuration file:

{
  "mcpServers": {
    "script": {
      "command": "/path-to/script-mcp"
    }
  }
}

Be sure to replace /path-to/script-mcp with the actual path to the Script Tool binary on your system.

Usage

Once configured, you can use the Script Tool to execute scripts safely through the MCP protocol. The tool supports:

Multiple interpreters (bash, python, etc.)
Timeout protection to prevent long-running scripts
Capturing both output and error streams
Cross-platform operation

The specific usage syntax will depend on the AI model you're using and how it interfaces with MCP servers.

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 "script" '{"command":"/path-to/script-mcp"}'

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": {
        "script": {
            "command": "/path-to/script-mcp"
        }
    }
}

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.

For Claude Desktop

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": {
        "script": {
            "command": "/path-to/script-mcp"
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
