mcp-server-tauri

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

> _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 aix to add the server to your AI assistant:

npx -y @a1st/aix add mcp tauri --command 'npx @hypothesi/tauri-mcp-server' --user

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

> [!TIP]

> `aix` automatically detects your installed AI assistants and configures them.

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:

1. Examine your project to see what's already configured

2. Show you what changes are needed (Cargo.toml, plugin registration, etc.)

3. 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)

Just type the command in your AI assistant to start a guided workflow.

Why this approach?

• ✅ Rich AI context — Screenshots, DOM, and logs help the AI understand your app's state
• ✅ Cross-platform — Works on Linux, Windows, macOS, Android, and iOS
• ✅ No external drivers — No Selenium, Playwright, or browser automation needed
• ✅ Native integration — Direct access to Tauri's IPC and backend
