Dev Toolkit MCP

72-tool MCP server covering iOS simulator, Android emulator, and Playwright web automation. One protocol, every MCP editor.

MCP server bridging AI editors with mobile simulators.

  • •See, interact with, and audit iOS + Android apps from your editor
  • •42 device control tools: screenshot, tap, swipe, type, dark mode, locale, permissions
  • •Autonomous agent DSL for multi-step flows in a single MCP call
  • •Accessibility audit and Store compliance checks
  • •Supports Claude Code, Copilot CLI, Cursor, Antigravity, VS Code Copilot Chat, Claude Desktop — any MCP client

Features

Device Control

42 tools for full simulator interaction.

  • •Capture screenshots to see UI state
  • •Tap, swipe, type text, press home
  • •Launch and terminate apps
  • •Set dark mode, change locale and location
  • •Grant privacy permissions
  • •Send simulated push notifications
  • •Override status bar for clean captures

Accessibility Audit

Automated accessibility scanning for iOS and Android.

  • •Detects missing VoiceOver labels and identifiers
  • •Flags small tap targets (below 44×44pt)
  • •Catches incorrect accessibility traits
  • •Scope filtering for specific screens or view hierarchies
  • •iOS via UI tree dump, Android via uiautomator

Store Compliance

Pre-submission validation for App Store and Play Store.

  • •Checks code signing and provisioning
  • •Detects debug tools left in release builds
  • •Validates privacy manifest (iOS)
  • •Verifies target SDK version (Android)
  • •Analyzes binary size
  • •Flags common rejection reasons before submit

Web Automation

8 Playwright-powered tools for headless browser automation.

  • •goto, click, type, eval JS, wait, extract text, screenshot, close
  • •Chromium / WebKit / Firefox selectable per call
  • •Optional peer dependency - zero bytes for mobile-only users

Autonomous Agent DSL

Single-call orchestration for multi-step flows.

  • •agent_run_steps executes { tool, args } step arrays in one MCP round trip
  • •Works across ios_* / android_* / web_* namespaces
  • •Returns per-step status + verdict (all_ok / partial / all_failed)
  • •Ideal for login flows, form fills, and multi-step QA paths

Xcode Build Wrapper

Progressive disclosure for xcodebuild — keeps build output out of agent context.

  • •ios_xcodebuild returns one line: SUCCESS|FAILURE (E errors, W warnings) plus xcresult ID
  • •ios_xcresult drills in by ID — modes: summary, errors, warnings, log, tests
  • •Saves thousands of tokens per build cycle vs raw xcodebuild output
  • •Build queue lock compatible — works inside multi-agent-pipeline Phase 3

Visual Regression

Pixel-based snapshot diff and App Store status-bar control.

  • •ios_visual_diff compares two PNGs via pixelmatch — returns diff_pct, pass/fail vs threshold, optional diff image
  • •ios_status_bar adds preset enum: clean (9:41 / 100% / WiFi for App Store screenshots), testing, low-battery, airplane, clear
  • •Useful for snapshot regression across light/dark, locale, dynamic-type variants

Multi-Editor Support

One-line setup across AI editors.

  • •Claude Code, Copilot CLI, Cursor, Antigravity, VS Code Copilot Chat, Claude Desktop — and any MCP-compatible client
  • •Same 72 tools via MCP protocol in every editor
  • •Graceful fallback if Xcode, Android SDK, or Playwright is missing
