Computer Use

go_computer_use_mcp_server

[!WARNING] This server is intended to run as a trusted local MCP tool.
It currently provides broad local desktop control and is not sandboxed by default.
Do not expose it to untrusted networks, users, or agents without additional security controls.

MCP (Model Context Protocol) server in Go for computer automation. Uses robotgo library for desktop automation.

Features

• Mouse control: movement, clicks, dragging, scrolling
• Keyboard control: key presses, text input, hotkeys
• Screen operations: screenshots, pixel color, display information
• Window management: move, resize, minimize/maximize
• Process management: list processes, search, terminate
• System utilities: system info, dialogs, delays

Quick Start with npx

The easiest way to run the server is via npx (requires Node.js 18+):

# Run with stdio transport (for MCP clients)
npx go-computer-use-mcp-server -t stdio

# Run with SSE transport
npx go-computer-use-mcp-server -t sse -h 0.0.0.0 -p 8080

Official MCP Registry

This server is prepared for publication in the Official MCP Registry as:

io.github.hightemp/go-computer-use-mcp-server

Registry metadata is defined in server.json. The npm package includes a matching mcpName field in package.json, which the registry uses to verify package ownership.

For maintainers, the release workflow publishes the npm package first, waits until that package version is visible in the npm registry, then publishes server.json with GitHub OIDC authentication.
