MCP server for cross-platform app testing

flutter-skill connects an AI agent to a running app so it can see the screen, tap, type, scroll, and verify behavior. It works through MCP for IDE agents and through an HTTP server for CLI and automation, with SDKs for multiple app frameworks.

370 stars54 forksDartUpdated 16d ago
Who it's for

Builders who want Claude Code, Cursor, Windsurf, or Copilot to run E2E tests across mobile, desktop, and web apps.

What it delivers

You can test real apps from natural language instead of writing and maintaining brittle E2E scripts.

What it does

MCP agent integration

Runs as an MCP server so agents can connect to live apps through standard tool calls.

Cross-platform support

Covers Flutter, React Native, iOS, Android, web, Electron, Tauri, KMP, and .NET MAUI.

Natural-language testing

Lets you ask an agent to explore flows, check errors, and validate screens in plain English.

HTTP automation mode

Provides `serve` and CLI commands for scripts, CI, and remote browser control.

Semantic page understanding

Uses accessibility trees and semantic refs like `button:Login` instead of brittle selectors.

Large tool set

Includes tools for screenshots, taps, text entry, assertions, mocking, visual regression, accessibility, and performance.

How to get it

  1. 11. Install (30 seconds)
    npm install -g flutter-skill
  2. 2Run
    npm install flutter-skill-react-native
  3. 3Run
    npm install flutter-skill-electron

🚀 Zero config. Zero test code. Just talk to your AI.

30-Second Demo

https://github.com/user-attachments/assets/d4617c73-043f-424c-9a9a-1a61d4c2d3c6

One prompt. 28 AI-driven actions. Zero test code. The AI explores a TikTok clone, navigates tabs, scrolls feeds, tests search, fills forms — all autonomously.


Why This Exists

Writing E2E tests is painful. Maintaining them is worse. flutter-skill takes a different approach:

  • 🔌 Connects any AI agent (Claude, Cursor, Windsurf, Copilot, OpenClaw) directly to your running app via MCP
  • 👀 The agent sees your screen — taps buttons, types text, scrolls, navigates — like a human tester who never sleeps
  • Zero test code — no Page Objects, no XPath, no brittle selectors. Just plain English
  • Zero config — 2 lines of code, works on all 10 platforms
You: "Test the checkout flow with an empty cart, then add 3 items and complete purchase"

Your AI agent handles the rest — screenshots, taps, text entry, assertions, navigation.
No Page Objects. No XPath. No brittle selectors. Just plain English.

Quick Start

1. Install (30 seconds)

npm install -g flutter-skill

2. Add to your AI (copy-paste into MCP config)

{
  "mcpServers": {
    "flutter-skill": {
      "command": "flutter-skill",
      "args": ["server"]
    }
  }
}

Works with Claude Desktop, Cursor, Windsurf, Copilot, Cline, OpenClaw — any MCP-compatible agent.

3. Add to your app (2 lines for Flutter)

import 'package:flutter_skill/flutter_skill.dart';

void main() {
  if (kDebugMode) FlutterSkillBinding.ensureInitialized();
  runApp(MyApp());
}

4. Test — just talk to your AI:

"Launch my app, explore every screen, and report any bugs"

That's it. Zero configuration. Zero test code. Works in under 60 seconds.

10 Platforms, One Tool

Most testing tools work on 1-2 platforms. flutter-skill works on 10.

PlatformSDKTest Score
Flutter (iOS/Android/Web)flutter_skill✅ 188/195

Total: 656/664 tests passing (98.8%) — each platform tested against a complex social media app with 50+ elements.


⚡ Performance

Real benchmarks from automated test runs against a complex social media app:

OperationWeb (CDP)ElectronAndroid
connect93 ms55 ms103 ms
tap1 ms1 ms2 ms
enter_text1 ms1 ms2 ms
inspect3 ms12 ms10 ms
snapshot2 ms8 ms29 ms
screenshot31 ms80 ms88 ms
eval1 ms

Token efficiency: snapshot() returns a structured element tree instead of an image — 87–99% fewer tokens than sending screenshots to your AI agent.

How fast is that? A tap takes 1–2 ms end-to-end. Browser automation tools like Playwright and Selenium typically take 50–100 ms for the same operation. That's 50–100× faster, because flutter-skill talks directly to the app runtime instead of going through WebDriver or CDP indirection.

Heavy DOM Sites (Real-World)

Tested 15 MCP tools against production websites — 75/75 passed, zero timeouts:

Total time includes page load. Tool execution is consistently sub-100ms even on heavy DOM sites.

🧠 AI-Native: 95% Fewer Tokens

Most AI testing tools send screenshots to the LLM — each one costs ~4,000 tokens.

flutter-skill uses Chrome's Accessibility Tree to give your AI a compact semantic summary of any page:

// page_summary → ~200 tokens (vs ~4,000 for a screenshot)
{
  "title": "Shopping Cart",
  "nav": ["Home", "Products", "Cart", "Account"],
  "forms": [{"input:Coupon Code": "text"}],
  "buttons": ["Apply", "Checkout", "Continue Shopping"],
  "features": {"search": true, "pagination": true},
  "links": 47, "inputs": 3
}

Then batch multiple actions in one call:

// explore_actions → 5 actions per call (vs 5 separate tool calls)
{"actions": [
  {"type": "fill", "target": "input:Coupon Code", "value": "SAVE20"},
  {"type": "tap", "target": "button:Apply"},
  {"type": "tap", "target": "button:Checkout"},
  {"type": "fill", "target": "input:Email", "value": "test@example.com"},
  {"type": "tap", "target": "button:Continue"}
]}

Result: Your AI agent tests faster, costs less, and understands pages better than screenshot-based tools.
