Metro MCP

A plugin-based MCP server for React Native runtime debugging, inspection, and automation. Connects to Metro bundler via Chrome DevTools Protocol - no app code changes needed for most features. It runs locally over stdio via the published package.

People who work with agentic ai, cdp and chrome devtools protocol and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
