Tauri Plugin: Model Context Protocol (MCP)

A Tauri plugin and MCP server that enables AI agents (Claude Code, Cursor, etc.) to interact with and debug Tauri desktop applications through standardized interfaces.

Features

The Tauri MCP Plugin provides a comprehensive set of tools that allow AI models and external applications to interact with Tauri applications:

Window Interaction

• Take Screenshot: Capture images of any Tauri window with configurable quality and size
• Window Management: Control window position, size, focus, minimize/maximize state
• DOM Access: Retrieve the HTML DOM content from webviews windows

User Input Simulation

• Mouse Movement: Simulate mouse clicks, movements, and scrolling
• Text Input: Programmatically input text into focused elements
• Execute JavaScript: Run arbitrary JavaScript code in the application context

Data & Storage

• Local Storage Management: Get, set, remove, and clear localStorage entries
• Ping: Simple connectivity testing to verify the plugin is responsive

Quick Start

Prerequisites

• Python 3.12+ - For the build script
• Rust & Cargo - For building the Tauri plugin
• Bun or npm - For building TypeScript components

Building the Project

This project uses a modern Python build system for managing both artifacts:

# Install Python dependencies
pip install -r requirements.txt

# Build everything (recommended)
python build.py all

# Or build individually
python build.py plugin  # Build Rust plugin + JS bindings
python build.py mcp     # Build TypeScript MCP server

For detailed build options and documentation, see BUILD.md.

Legacy Build Commands

If you prefer manual builds:

# Plugin
bun install
bun run build && bun run build-plugin

# MCP Server
cd mcp-server-ts
bun install
bun run build

Basic Configuration

Add to your Claude Code or Cursor MCP settings:

{
  "mcpServers": {
    "tauri-mcp": {
      "command": "node",
      "args": ["/path/to/tauri-plugin-mcp/mcp-server-ts/build/index.js"]
    }
  }
}

Architecture

The plugin uses a multi-layer communication stack:

AI Agent (Claude Code/Cursor)
         ↓ (MCP Protocol)
    MCP Server (Node.js)
         ↓ (IPC/TCP Socket)
   Socket Server (Rust)
         ↓ (Tauri APIs)
   Tauri Application

Supports both IPC (Unix sockets/named pipes) and TCP connections for maximum flexibility.
