Learn more about [Playwright MCP](https://github.com/microsoft/playwright-mcp). ### Key Features -- **Fast and lightweight**. Uses Playwright's accessibility tree, not pixel-based input. -- **LLM-friendly**. No vision models needed, operates purely on structured data. -- **Deterministic tool application**. Avoids ambiguity common with screenshot-based approaches. +- **Token-efficient**.

You can specify the configuration file using the `--config` command line option: ```bash -# Windows -%USERPROFILE%\AppData\Local\ms-playwright\mcp-{channel}-profile - -# macOS -- ~/Library/Caches/ms-playwright/mcp-{channel}-profile - -# Linux -- ~/.cache/ms-playwright/mcp-{channel}-profile +playwright-cli --config path/to/config.json open example.com ``` -**Isolated** - -In the isolated mode, each session is started in the isolated profile. Every time you ask MCP to close the browser, -the session is closed and all the storage state for this session is lost. You can provide initial storage state -to the browser via the config's `contextOptions` or via the `--storage-state` argument. Learn more about the storage -state [here](https://playwright.dev/docs/auth). - -```js -{ - "mcpServers": { - "playwright": { - "command": "npx", - "args": [ - "@playwright/mcp@latest", - "--isolated", - "--storage-state={path/to/storage.json}" - ] - } - } -} -``` - -**Browser Extension** - -The Playwright MCP Chrome Extension allows you to connect to existing browser tabs and leverage your logged-in sessions and browser state. See [packages/extension/README.md](packages/extension/README.md) for installation and setup instructions. - -### Initial state - -There are multiple ways to provide the initial state to the browser context or a page. - -For the storage state, you can either: -- Start with a user data directory using the `--user-data-dir` argument. This will persist all browser data between the sessions. -- Start with a storage state file using the `--storage-state` argument. This will load cookies and local storage from the file into an isolated browser context. - -For the page state, you can use: - -- `--init-page` to point to a TypeScript file that will be evaluated on the Playwright page object. This allows you to run arbitrary code to set up the page. - -```ts -// init-page.ts -export default async ({ page }) => { - await page.context().grantPermissions(['geolocation']); - await page.context().setGeolocation({ latitude: 37.7749, longitude: -122.4194 }); - await page.setViewportSize({ width: 1280, height: 720 }); -}; -``` - -- `--init-script` to point to a JavaScript file that will be added as an initialization script. The script will be evaluated in every page before any of the page's scripts. -This is useful for overriding browser APIs or setting up the environment. - -```js -// init-script.js -window.isPlaywrightMCP = true; -``` - -### Configuration file - -The Playwright MCP server can be configured using a JSON configuration file. You can specify the configuration file -using the `--config` command line option: - -```bash -npx @playwright/mcp@latest --config path/to/config.json -``` +Playwright CLI will load config from `playwright-cli.json` by default so that you did not need to specify it every time.
