Chrome DevTools

Provides direct Chrome browser control through DevTools for web automation, debugging, and performance analysis using accessibility tree snapshots for reliable element targeting, automatic page event handling, and integrated performance tracing with actionable insights.

This MCP server provides AI assistants with direct control over Chrome browsers through Chrome DevTools, enabling reliable web automation, debugging, and performance analysis using Puppeteer for browser control and Chrome DevTools for trace recording. Built by Google with TypeScript, it offers 26 tools across categories including input automation (clicking, filling forms, drag-and-drop), navigation (page management, history), network analysis (request inspection, throttling), performance tracing with Chrome DevTools insights, console debugging, and screenshot/snapshot capabilities. The implementation uses accessibility tree snapshots for reliable element targeting, automatically waits for page events after actions, supports CPU and network emulation for testing, and integrates Chrome's performance trace engine for actionable insights, making it valuable for automated testing workflows, web debugging, performance optimization, and building AI assistants that need to interact with live web applications through a real browser environment.
