v0.2.0

March 28, 2026

Added

• Profiler plugin — CPU and render profiling for React Native apps without requiring the React DevTools browser extension
  • start_profiling / stop_profiling tools capture per-component render durations across all commits by patching __REACT_DEVTOOLS_GLOBAL_HOOK__ at runtime; works on New Architecture (Bridgeless/Fusebox) and legacy bridge
  • get_flamegraph tool and metro://profiler/flamegraph resource render a ranked component chart with time bars
  • metro://profiler/data resource exposes raw commit data as JSON for agent analysis
  • get_react_renders tool reads timings from <Profiler onRender={trackRender}> wrappers with memoization savings %
  • get_profile_status reports active profiling mode and previous profile availability
  • Auto-detects Fusebox targets and skips unsupported CDP fallbacks
  • New profiler.newArchitecture config option (default true)
• trackRender client SDK export — drop-in onRender callback for React <Profiler>, records to globalThis.__METRO_MCP__.renders (capped at 200 entries)

Changed

• debug-performance prompt updated to walk through CPU profiling + React render analysis + network checks
• Client SDK bundle target changed to browser to fix import.meta crash on Hermes
• All global references in client SDK changed to globalThis for Hermes compatibility

Fixed

• CDPConnection interface now exposes getTarget() for target capability detection
• MetroTarget type extended with reactNative.capabilities.prefersFuseboxFrontend
