quality-engineering-appium-mcp
Drives iOS/Android mobile devices via Appium MCP. Runs a preflight, picks local emulator/simulator/USB or a device cloud, captures screenshots/page source into a named evidence dir. Use for verifying mobile bugs, E2E tests, and navigating real device clouds (LambdaTest/BrowserStack).

📱 Appium MCP (Mobile Automation)
Priority: P1 (HIGH)
[!IMPORTANT] Tier 0 (Infrastructure): Session creation, device farm connectivity, basic OS interactions. Tier 1 (Core Gestures): Taps, swipes, text input for native mobile elements. Tier 2 (Flutter/Single-Canvas): Visual-first automation via screenshot + coordinate taps.
🔌 Activation
Triggers: appium, appium-mcp, appium doctor, mobile verify, android verify, ios verify, lambdatest, real device cloud, flutter widget tap.
🪜 Driver Ladder
sh scripts/preflight.sh— printsMODE: local | local,remote | remote | none; exit 0 usable, 2 not.- Local:
select_device(Android) orprepare_ios_simulator(iOS), embedded drivers. Needs Node 22+, JDK 8+ / Xcode. - Cloud:
remoteServerUrl(LambdaTest/BrowserStack). URL must matchREMOTE_SERVER_URL_ALLOW_REGEX. - Neither: ask for exported screenshots or cloud video link; label
human-provided. - Nothing exported: return
BLOCKED (driver: appium), continue other lanes.
NO_UI=true default; AI_VISION_ENABLED=true only for Flutter/canvas. Local single-user or trusted CI only. generate_locators / appium_generate_tests feed test-loop step 4. Full table: driver-ladder.
🛠 Core Workflow (Goal-Oriented)
| Step | Tool | Purpose |
|---|---|---|
| 0 | select_device / prepare_ios_simulator | Pick target per ladder rung; cloud skips this. |
| 1 | appium_session_management (create) | Open session. Resiliency: Retry with noReset: true on failure. |
| 2 | appium_get_window_size | Scale coordinates for high-density displays. |
| 3 | appium_screenshot | Capture visual state for Semantic Reasoning. |
| 4 | appium_gesture / appium_set_value | Interact. Self-Healing: Re-scan hierarchy if UUID stale. |
| 5 | appium_session_management (delete) | MANDATORY Cleanup. |
💡 AI-Driven Methodologies
- Semantic Intent: Find element in hierarchy (e.g., "Login button") instead of raw coordinates. Resilient to layout shifts.
- Dynamic Handling: Unexpected pop-up appears? Pause, reason about alert, dismiss, resume.
- Visual Anchors: Find stable "Anchor" (e.g., Header) and derive coordinates relative to it.
🚫 Anti-Patterns (Zero-Tolerance)
- Hardcoded XPaths: Use
accessibility idoruiautomator. XPath flaky. - Implicit Wait-Only: Never assume page loaded. Poll for "Source of Truth" element.
- Ignoring QoS: Audit CPU/Memory via
appium_mobile_performance_data. Prevent lag/crashes. - Orphaned Sessions: Teardown mandatory. Call
deletein cleanup block.
📁 Evidence
.appium-mcp/<session>/: <AC|step>-<before|after>.png (nav shots at maxWidth budget, verdict full-res), <label>.source.xml from appium_get_page_source, perf.json, video.url. Walkthrough records driver: + evidence_dir:.
✅ Evaluation Criteria
- Cleanup Rate: 100% session closure.
- Visual Accuracy: Coordinate-based taps land within 5% of target center.
- Security: No secrets in tool arguments or logs.
