| 4 | |
| 5 | Chrome DevTools for agents (`chrome-devtools-mcp`) lets your coding agent (such as Antigravity, Claude, Cursor or Copilot) |
| 6 | control and inspect a live Chrome browser. It acts as a Model-Context-Protocol |
| 7 | (MCP) server, giving your AI coding assistant access to the full power of |
| 8 | Chrome DevTools for reliable automation, in-depth debugging, and performance analysis. |
| 9 | A [CLI](docs/cli.md) is also provided for use without MCP. |

| 12 | |
| 13 | ## Key features |
| 14 | |
| 15 | - **Get performance insights**: Uses [Chrome |
| 16 | DevTools](https://github.com/ChromeDevTools/devtools-frontend) to record |
| 17 | traces and extract actionable performance insights. |
| 18 | - **Advanced browser debugging**: Analyze network requests, take screenshots and |
| 19 | check browser console messages (with source-mapped stack traces). |
| 20 | - **Reliable automation**. Uses |
| 21 | [puppeteer](https://github.com/puppeteer/puppeteer) to automate actions in |
| 22 | Chrome and automatically wait for action results. |
| 23 | |
| 24 | ## Disclaimers |
| 25 | |
| 26 | `chrome-devtools-mcp` exposes content of the browser instance to the MCP clients |
| 27 | allowing them to inspect, debug, and modify any data in the browser or DevTools. |
| 28 | Avoid sharing sensitive or personal information that you don't want to share with |
| 29 | MCP clients. |
| 30 | |
| 31 | `chrome-devtools-mcp` officially supports Google Chrome and [Chrome for Testing](https://developer.chrome.com/blog/chrome-for-testing/) only. |
| 32 | Other Chromium-based browsers may work, but this is not guaranteed, and you may encounter unexpected behavior. Use at your own discretion. |
| 33 | We are committed to providing fixes and support for the latest version of [Extended Stable Chrome](https://chromiumdash.appspot.com/schedule). |
| 34 | |
| 35 | Performance tools may send trace URLs to the Google CrUX API to fetch real-user |
| 36 | experience data. This helps provide a holistic performance picture by |
| 37 | presenting field data alongside lab data. This data is collected by the [Chrome |
| 38 | User Experience Report (CrUX)](https://developer.chrome.com/docs/crux). To disable |
| 39 | this, run with the `--no-performance-crux` flag. |
| 40 | |
| 41 | ## **Usage statistics** |
| 42 | |
| 43 | Google collects usage statistics (such as tool invocation success rates, latency, and environment information) to improve the reliability and performance of Chrome DevTools MCP. |
| 44 | |
| 45 | Data collection is **enabled by default**. You can opt-out by passing the `--no-usage-statistics` flag when starting the server: |
| 46 | |
| 47 | ```json |
| 48 | "args": ["-y", "chrome-devtools-mcp@latest", "--no-usage-statistics"] |
| 49 | ``` |
| 50 | |
| 51 | Google handles this data in accordance with the [Google Privacy Policy](https://policies.google.com/privacy). |
| 52 | |
| 53 | Google's collection of usage statistics for Chrome DevTools MCP is independent from the Chrome browser's usage statistics. Opting out of Chrome metrics does not automatically opt you out of this tool, and vice-versa. |
| 54 | |
| 55 | Collection is disabled if `CHROME_DEVTOOLS_MCP_NO_USAGE_STATISTICS` or `CI` env variables are set. |
| 56 | |
| 57 | ## Update checks |
| 58 | |
| 59 | By default, the server periodically checks the npm registry for updates and logs a notification when a newer version is available. |
| 60 | You can disable these update checks by setting the `CHROME_DEVTOOLS_MCP_NO_UPDATE_CHECKS` environment variable. |
| 61 | |
| 62 | ## Requirements |
| 63 | |
| 64 | - [Node.js](https://nodejs.org/) [LTS](https://github.com/nodejs/Release#release-schedule) version. |
| 65 | - [Chrome](https://www.google.com/chrome/) current stable version or newer. |
| 66 | - [npm](https://www.npmjs.com/) |
| 67 | |
| 68 | ## Getting started |
| 69 | |
| 70 | Add the following config to your MCP client: |
| 71 | |
| 72 | ```json |
| 73 | { |
| 74 | "mcpServers": { |
| 75 | "chrome-devtools": { |
| 76 | "command": "npx", |
| 77 | "args": ["-y", "chrome-devtools-mcp@latest"] |
| 78 | } |
| 79 | } |
| 80 | } |
| 81 | ``` |
| 82 | |
| 83 | > [!NOTE] |
| 84 | > Using `chrome-devtools-mcp@latest` ensures that your MCP client will always |
