mcp-cdp MCP

A safe-by-default MCP server that drives an Electron or Chrome app over the Chrome DevTools Protocol (CDP). It allows agents to inspect DOM snapshots, query elements, view console logs and network requests, take screenshots, and perform read-write actions like clicking, typing, and navigating. It supports parallel agents via separate debugging ports and works across macOS, Linux, and Windows.
