ExecBro Overview

ExecBro MCP server connects AI agents to running React Native apps through Metro discovery and runtime tools. It captures console logs and network requests, inspects screen structure, takes screenshots, performs UI actions, and evaluates JavaScript in the app runtime. Reach for it when an agent needs to investigate, reproduce, or verify behavior on an iOS simulator or Android device without adding application code. An optional SDK improves startup-time log, network, and state capture, but the server can start without code changes.
