chrome-devtools-mcp vs agnt
chrome-devtools-mcp: chrome-devtools-mcp enables AI coding assistants like Gemini, Claude, and Copilot to interact with a live Chrome browser via the Model-Context-Protocol (MCP). It grants AI full access to Chrome DevTools for reliable automation, deep debugging, and detailed performance insights.; agnt: agnt is a tool that bridges AI coding agents with the browser, providing visual debugging, real-time error capture, and interactive feedback capabilities. It allows agents to 'see' and 'interact' with web applications, significantly enhancing the AI-assisted development workflow.

TL;DR
chrome-devtools-mcpBrowser Automation · ★ 54.0k
When to choose:
- You want an agent to record a Chrome performance trace and get insights from it; the README lists performance_start_trace, performance_stop_trace and performance_analyze_insight.
- You need to inspect network requests, console messages and screenshots of a page while debugging it.
- You want the agent to attach to a Chrome you already have running, using --browser-url, --ws-endpoint or --autoConnect (Chrome 144+).
When to skip:
- You need Firefox or Safari: the project is built on Chrome DevTools and targets Chrome.
- You want a general-purpose automation or test runner across browsers; Playwright MCP is the closer fit.
- You cannot run Node.js 20.19 or newer, which the README lists as a requirement.
