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 Android emulators & iOS simulators
📋 Logs	Stream console, Android logcat, iOS, and system logs

Quick Start

1. Add the MCP Bridge Plugin to Your Tauri App

cargo add tauri-plugin-mcp-bridge

// src-tauri/src/main.rs
fn main() {
    let mut builder = tauri::Builder::default();

    #[cfg(debug_assertions)]
    {
        builder = builder.plugin(tauri_plugin_mcp_bridge::init());
    }

    builder
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

Note: The npm package @hypothesi/tauri-plugin-mcp-bridge is optional—only needed if you want to call the plugin from your app's frontend code. The MCP server communicates with the Rust plugin directly via WebSocket.

2. 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

Terminal CLI

If you want to call the same tools directly from a shell, install the companion CLI package:

npm install -g @hypothesi/tauri-mcp-cli
tauri-mcp driver-session start --port 9223
tauri-mcp driver-session status --json

The CLI keeps the underlying MCP server warm in the background so stateful commands such as driver_session work across separate invocations.

Multi-App Support

The MCP server supports connecting to multiple Tauri apps simultaneously. Each app runs on a unique port, and the most recently connected app becomes the "default" app.

Key Features:

• Connect to multiple apps on different ports
• Default app used when no appIdentifier specified
• Target specific apps using port number or bundle ID
• Stop individual sessions or all sessions at once

Example Usage:

// Connect to first app
await driver_session({ action: "start", port: 9223 })

// Connect to second app
await driver_session({ action: "start", port: 9224 })

// Check status - shows both apps with default indicator
await driver_session({ action: "status" })

// Use default app (most recent - port 9224)
await webview_screenshot()

// Target specific app by port
await webview_screenshot({ appIdentifier: 9223 })

// Stop specific app
await driver_session({ action: "stop", appIdentifier: 9223 })

// Stop all apps
await driver_session({ action: "stop" })
