chrome-devtools-mcp vs plasmate

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.; plasmate: Plasmate compiles HTML into a Semantic Object Model (SOM), a structured representation that LLMs can reason about directly. It runs JavaScript via V8, supports Puppeteer via CDP, and produces output that is 10-800x smaller than raw HTML. It is purpose-built for AI agent pipelines, with MCP, Vercel AI SDK integrations, and over 60 ecosystem integrations.

TL;DR

chrome-devtools-mcp logo
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.
