flutter-skill is a broad, third-party MCP testing server that connects AI agents to running apps across 10 platforms (Flutter, React Native, iOS, Android, Web, Electron, Tauri, KMP, .NET MAUI) via roughly 253 self-described tools, emphasizing zero test code and low token usage through accessibility-tree snapshots. It requires granting the AI agent fairly broad control over the app/browser under test and the ability to alter network behavior (including arbitrary JS execution via eval), so it's best suited to trusted local development or CI environments. As a community-maintained, pre-1.0 project, evaluate its maturity and security boundaries before adopting it for sensitive or production-adjacent testing.

FS_PORT
Optional port for HTTP serve mode (`flutter-skill serve`); can also be set via the `--port=N` flag.
FS_HOST
Optional host for HTTP serve mode (`flutter-skill serve`); can also be set via the `--host=H` flag.
1) Install globally: npm install -g flutter-skill (Homebrew, Scoop, a Docker image, or dart pub global activate flutter_skill are also documented). 2) Add the install_config shown here to your AI client's MCP configuration (e.g. Cursor's .cursor/mcp.json, Claude Desktop's claude_desktop_config.json, Windsurf's ~/.codeium/windsurf/mcp_config.json, or VSCode's .vscode/mcp.json). 3) Add the matching SDK to the app under test — e.g. for Flutter, add the flutter_skill dependency and call FlutterSkillBinding.ensureInitialized() in main() under kDebugMode; separate SDK packages exist for React Native, Electron, iOS, Android, Tauri, KMP, and .NET MAUI. 4) Restart the AI client and issue natural-language test instructions, e.g. "launch my app and explore every screen".
{"mcpServers":{"flutter-skill":{"command":"flutter-skill","args":["server"]}}}
Shown for Claude Desktop. Other clients may use a different file or key (VS Code uses "servers") — the configurator below converts it.
{
"servers": {
"flutter-skill": {
"command": "flutter-skill",
"args": [
"server"
]
}
}
}
Goes in your project's .vscode/mcp.json (VS Code uses a "servers" key).

Run it in a terminal; replace any <…> placeholders with your own values first.
Run `npm install -g flutter-skill`, add the flutter-skill MCP config to your client and restart it, then confirm the `page_summary` and `screenshot` tools appear in the client's tool list. Alternatively run `flutter-skill tools` to list all available tools.
Once connected, you can ask your AI assistant things like:

flutter-skill is an open-source MCP server (npm package flutter-skill, Dart package flutter_skill) that connects AI agents such as Claude, Cursor, Windsurf, and Copilot directly to a running app over the Model Context Protocol. It exposes roughly 253 MCP tools for screenshots, accessibility-tree snapshots, taps, text entry, scrolling, assertions, visual regression, network mocking, coverage tracking, multi-device sync, accessibility audits, performance monitoring, and test recording/export, and claims support for 10 platforms — Flutter, React Native, iOS, Android, Web, Electron, Tauri, KMP, and .NET MAUI. It advertises zero test code and zero configuration, driven purely by natural language, and also ships a separate HTTP serve mode with a CLI client. The repository is MIT-licensed.
