# AI use cases for Chrome DevTools MCP (ChromeDevTools/chrome-devtools-mcp) Repo: [ChromeDevTools/chrome-devtools-mcp](https://github.com/ChromeDevTools/chrome-devtools-mcp) | Use cases: 3 | Page: https://dedupedai.com/use-cases/chromedevtools-chrome-devtools-mcp/ Chrome DevTools for agents (chrome-devtools-mcp) lets a coding agent such as Claude, Cursor, Copilot or Antigravity control and inspect a live Chrome browser, as an MCP server or as a CLI. The agent can record performance traces and get insights, read network requests and console messages with source-mapped stack traces, take screenshots, and automate pages with Puppeteer. The README warns that it exposes the browser's content to the MCP client, so avoid sensitive sites in that browser. This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL. - Let your coding agent debug a page in a real Chrome: https://dedupedai.com/use-cases/chromedevtools-chrome-devtools-mcp/let-your-agent-debug-a-page-in-real-chrome/ - Have an agent record a performance trace and explain it: https://dedupedai.com/use-cases/chromedevtools-chrome-devtools-mcp/get-performance-insights-from-a-trace/ - Drive Chrome from the command line with the DevTools CLI skill: https://dedupedai.com/use-cases/chromedevtools-chrome-devtools-mcp/drive-chrome-from-the-cli-with-a-skill/ ## How to let your coding agent debug a page in a real Chrome with Chrome DevTools MCP Repo: [ChromeDevTools/chrome-devtools-mcp](https://github.com/ChromeDevTools/chrome-devtools-mcp) | Difficulty: Beginner | Time: 10 minutes | Basis: From the README Add the MCP server so the agent can open your app, read the console and network, and screenshot the result. **Who it is for:** A frontend developer whose agent keeps 'fixing' bugs it never actually saw in the browser. **The problem:** Agents edit code blind and claim a fix works without loading the page. **The outcome:** An agent that opens the page, reads console errors and failed requests, fixes the code and checks again. ### Steps 1. Add an mcpServers entry named chrome-devtools that runs npx with `chrome-devtools-mcp@latest` 2. Restart your MCP client so the tools load 3. Ask the agent to open your local app and report console messages and failed network requests 4. Have it fix the cause and take a screenshot to confirm ### Prompt to paste into your agent ```text Add ChromeDevTools/chrome-devtools-mcp to my MCP config, open http://localhost:, list every console error and failed network request with its source-mapped stack, fix the top one, and take a screenshot after the fix. ``` ### Caveat The server exposes everything in that browser to the MCP client; do not use a profile that is signed in to sensitive accounts.

Install the MCP server in your client 2. Prompt: Check the performance of https://developers.chrome.com (or your own URL) 3. Read the insights the agent extracts from the trace 4. Ask it to apply the top fix and re-run the trace ### Prompt to paste into your agent ```text Using ChromeDevTools/chrome-devtools-mcp, record a performance trace of , list the top 3 insights with their likely cause in my code, and re-measure after fixing the first one. ``` ### Caveat Disclaimer: Third-party repos we don't own or vouch for.

Install globally: `npm i chrome-devtools-mcp@latest -g` 2. Open a page: `chrome-devtools navigate_page 1 --url "https://developers.chrome.com"` 3. Capture it: `chrome-devtools take_screenshot 1 --filePath screenshot.png`, then `chrome-devtools stop` 4. For Claude Code, copy the chrome-devtools-cli skill folder into ~/.claude/skills/ ### Prompt to paste into your agent ```text Install ChromeDevTools/chrome-devtools-mcp globally, add the chrome-devtools-cli skill for my agent, and write a script that screenshots each URL in urls.txt into ./shots/. ``` ### Caveat Disclaimer: Third-party repos we don't own or vouch for.
