tauri-mcp

A Tauri plugin that lets AI agents (Claude Code, Cursor, etc.) interact with your Tauri app through screenshots, DOM inspection, and input simulation using the Model Context Protocol (MCP).

Features

  • Screenshots — capture the app window on macOS, Linux, and Windows

  • DOM access — read the full HTML of any webview window

  • Element interaction — click, type, drag, hover via simulated input

  • JavaScript execution — run arbitrary JS in the webview context

  • Element position — find elements by id, class, tag, or text content

Installation

# Cargo.toml [dependencies] tauri-plugin-mcp = { git = "https://github.com/DonsWayo/tauri-mcp", optional = true }

Register the plugin in your Tauri app:

// src-tauri/src/lib.rs #[cfg(feature = "mcp-e2e")] app.plugin(tauri_plugin_mcp::init())?;

The plugin opens a Unix domain socket at /tmp/<app-name>-mcp.sock that MCP clients connect to.

macOS Screenshots

The plugin uses screencapture -l <CGWindowID> instead of xcap. This means:

  • No Screen Recording permission required for the Tauri app itself

  • Only Terminal (or your terminal emulator) needs Screen Recording access

  • Works with unsigned debug builds without code signing entitlements

  • Avoids a crash in xcap::Window::all() triggered by certain system windows on recent macOS versions

Linux Screenshots

Uses xcap for X11 window capture with multi-pass window matching by app name and title.

Usage with Claude Code

Add to .mcp.json:

{ "mcpServers": { "nucel-e2e": { "type": "stdio", "command": "node", "args": ["path/to/mcp-server/build/index.js", "/tmp/your-app-mcp.sock"] } } }

This project started as a fork of P3GLEG/tauri-plugin-mcp and has since diverged significantly.
