MCP Server Tauri

Give your AI assistant superpowers for Tauri development

Documentation · Getting Started · Available Tools

A Model Context Protocol (MCP) server that enables AI assistants like Claude, Cursor, and Windsurf to build, test, and debug Tauri® v2 applications. Screenshots, DOM state, and console logs from your running app give the AI rich context to understand what's happening—and tools to interact with it.

✨ Features

Category	Capabilities
🎯 UI Automation	Screenshots, clicks, typing, scrolling, element finding, visual element picker
🔍 IPC Monitoring	Capture and inspect Tauri IPC calls in real-time
📱 Mobile Dev	List iOS simulators & Android emulators
📋 Logs	Stream console, Android logcat, iOS, and system logs

Disclaimer: This MCP was developed using agentic coding tools. It may contain bugs.

🚀 Quick Start

Prerequisites

Node.js 20+ and npm
Rust and Cargo (for Tauri development)
Tauri CLI: npm install -g @tauri-apps/cli@next
For mobile: Xcode (macOS) or Android SDK

1. Configure Your AI Assistant

Use install-mcp to add the server to your AI assistant:

npx -y install-mcp @hypothesi/tauri-mcp-server --client claude-code

Supported clients: claude-code, cursor, windsurf, vscode, cline, roo-cline, claude, zed, goose, warp, codex

Claude Code

npx -y install-mcp @hypothesi/tauri-mcp-server --client claude-code

Cursor

npx -y install-mcp @hypothesi/tauri-mcp-server --client cursor

VS Code / Copilot

npx -y install-mcp @hypothesi/tauri-mcp-server --client vscode

Windsurf

npx -y install-mcp @hypothesi/tauri-mcp-server --client windsurf

Cline

npx -y install-mcp @hypothesi/tauri-mcp-server --client cline

Restart your AI assistant after adding the configuration.

CLI Usage

If you want to call the tools directly from a terminal instead of from an MCP client:

npm install -g @hypothesi/tauri-mcp-cli
tauri-mcp driver-session start --port 9223
tauri-mcp webview-screenshot --file screenshot.png

The CLI uses MCPorter keep-alive support so driver_session state survives across separate commands.

2. Set Up the MCP Bridge Plugin

Ask your AI assistant to help configure your Tauri app:

"Help me set up the Tauri MCP Bridge plugin"

Your AI will:

Examine your project to see what's already configured
Show you what changes are needed (Cargo.toml, plugin registration, etc.)
Ask for your permission before making any modifications

That's it! The AI handles all the setup details while keeping you in control. 🎉

Manual Setup

If you prefer to set up manually, see the Getting Started guide or the plugin documentation.

💬 Slash Commands (Prompts)

Command	Description
`/setup`	Set up or update the MCP bridge plugin in your Tauri project
`/fix-webview-errors`	Find and fix JavaScript errors in your webview
