Metro MCP

steve228uk/metro-mcp

Hooks into Metro bundler and Hermes via Chrome DevTools Protocol to expose React Native and Expo runtime state as MCP tools. No app code changes needed. Query console logs, inspect network requests, evaluate JavaScript in the running app, control simulators, trigger deep links, read AsyncStorage, and symbolicate stack traces. Includes Redux state inspection, React component tree walking, and test recording that generates Appium or Maestro scripts from your interactions. Built-in CDP proxy lets you use Chrome DevTools alongside the MCP connection without disconnecting. Supports iOS simulators via xcrun simctl and Android devices via adb, with optional IDB for advanced iOS operations.
