rn-devtools-hub MCP

An agent runtime for React Native and Expo that acts as an MCP server. It allows agents to see the app structure via React's dev bookkeeping, find elements by role, act through props, prove steps with runtime evidence, and inspect network requests without screenshots. It runs locally with zero dependencies and no telemetry.
