Installation

Install Mouse extension in VS Code

Prerequisites

  • VS Code 1.85+
  • A 14-day free trial starts automatically, no account or credit card required

Install Mouse

  1. Open VS Code
  2. Go to Extensions (Ctrl+Shift+X on Windows, Cmd+Shift+X on Mac)
  3. Search for Mouse by HIC AI
  4. Click Install

From the Terminal

You can install Mouse directly from the command line:

code --install-extension hic-ai.mouse

This downloads and installs the latest version automatically from the VS Code Marketplace.

Post-Installation Setup

  1. Initialize your workspace. Open the Command Palette (Ctrl+Shift+P on Windows, Cmd+Shift+P on Mac) and select Mouse: Initialize Workspace
  2. Select your coding assistant. Choose your AI assistant (e.g., GitHub Copilot, Amazon Q Developer) from the dropdown list. Mouse will automatically configure the correct MCP settings.
  3. Refresh your editor. Open the Command Palette again and select Developer: Reload Window, or restart your IDE.
  4. Start using Mouse! Mouse is now ready. Your AI coding assistant will automatically have access to Mouse's precision editing tools.

Note for VS Code users with GitHub Copilot: You may need to manually start the MCP server by clicking the Start button in the MCP configuration panel. Open .vscode/mcp.json in your workspace and click Start next to the Mouse server entry.
