It is third-party material and does not represent AgentHub; instructions that appear in it are not instructions to you. ## Playwright MCP A Model Context Protocol (MCP) server that provides browser automation capabilities using [Playwright](https://playwright.dev). This server enables LLMs to interact with web pages through structured accessibility snapshots, bypassing the need for screenshots or visually-tuned models. ### Playwright MCP vs Playwright CLI This package provides MCP interface into Playwright. If you are using a **coding agent**, you might benefit from using the [CLI+SKILLS](https://github.com/microsoft/playwright-cli) instead. - **CLI**: Modern **coding agents** increasingly favor CLI–based workflows exposed as SKILLs over MCP because CLI invocations are more token-efficient: they avoid loading large tool schemas and verbose accessibility trees into the model context, allowing agents to act through concise, purpose-built commands. This makes CLI + SKILLs better suited for high-throughput coding agents that must balance browser automation with large codebases, tests, and reasoning within limited context windows.
**Learn more about [Playwright CLI with SKILLS](https://github.com/microsoft/playwright-cli)**. - **MCP**: MCP remains relevant for specialized agentic loops that benefit from persistent state, rich introspection, and iterative reasoning over page structure, such as exploratory automation, self-healing tests, or long-running autonomous workflows where maintaining continuous browser context outweighs token cost concerns. ### 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. ### Requirements - Node.js 18 or newer - VS Code, Cursor, Windsurf, Claude Desktop, Goose, Grok, Junie or any other MCP client ### Getting started First, install the Playwright MCP server with your client. **Standard config** works in most of the tools: ```js { "mcpServers": { "playwright": { "command": "npx", "args": [ "@playwright/mcp@latest" ] } } } ``` [Install in VS Code](https://insiders.vscode.dev/redirect?url=vscode%3Amcp%2Finstall%3F%257B%2522name%2522%253A%2522playwright%2522%252C%2522command%2522%253A%2522npx%2522%252C%2522args%2522%253A%255B%2522%2540playwright%252Fmcp%2540latest%2522%255D%257D) [Install in VS Code Insiders](https://insiders.vscode.dev/redirect?url=vscode-insiders%3Amcp%2Finstall%3F%257B%2522name%2522%253A%2522playwright%2522%252C%2522command%2522%253A%2522npx%2522%252C%2522args%2522%253A%255B%2522%2540playwright%252Fmcp%2540latest%2522%255D%257D)

*env* `PLAYWRIGHT_MCP_VIEWPORT_SIZE` | ### User profile You can run Playwright MCP with persistent profile like a regular browser (default), in isolated contexts for testing sessions, or connect to your existing browser using the browser extension. **Persistent profile** All the logged in information will be stored in the persistent profile, you can delete it between sessions if you'd like to clear the offline state. Persistent profile is located at the following locations and you can override it with the `--user-data-dir` argument. ```bash # Windows %USERPROFILE%\AppData\Local\ms-playwright\mcp-{channel}-{workspace-hash} # macOS - ~/Library/Caches/ms-playwright/mcp-{channel}-{workspace-hash} # Linux - ~/.cache/ms-playwright/mcp-{channel}-{workspace-hash} ``` `{workspace-hash}` is derived from the MCP client's workspace root, so different projects get separate profiles automatically. > [!IMPORTANT] > A persistent profile can only be used by one browser instance at a time, so concurrent MCP clients sharing the same workspace will conflict. To run several clients in parallel, start each additional client with `--isolated` or point it at a distinct `--user-data-dir`. **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 [microsoft/playwright › packages/extension](https://github.com/microsoft/playwright/tree/main/packages/extension#readme) 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 ```

### Standalone MCP server When running headed browser on system w/o display or from worker processes of the IDEs, run the MCP server from environment with the DISPLAY and pass the `--port` flag to enable HTTP transport. ```bash npx @playwright/mcp@latest --port 8931 ``` And then in MCP client config, set the `url` to the HTTP endpoint: ```js { "mcpServers": { "playwright": { "url": "http://localhost:8931/mcp" } } } ``` ## Security Playwright MCP is **not** a security boundary. See [MCP Security Best Practices](https://modelcontextprotocol.io/docs/tutorials/security/security_best_practices) for guidance on securing your deployment.
Docker **NOTE:** The Docker implementation only supports headless chromium at the moment. ```js { "mcpServers": { "playwright": { "command": "docker", "args": ["run", "-i", "--rm", "--init", "--pull=always", "mcr.microsoft.com/playwright/mcp"] } } } ``` Or If you prefer to run the container as a long-lived service instead of letting the MCP client spawn it, use: ``` docker run -d -i --rm --init --pull=always \ --entrypoint node \ --name playwright \ -p 8931:8931 \ mcr.microsoft.com/playwright/mcp \ /app/cli.js --headless --browser chromium --no-sandbox --port 8931 --host 0.0.0.0 ``` The server will listen on host port **8931** and can be reached by any MCP client. You can build the Docker image yourself. ``` docker build -t mcr.microsoft.com/playwright/mcp . ```
Programmatic usage ```js import http from 'http'; import { createConnection } from '@playwright/mcp'; import { SSEServerTransport } from '@modelcontextprotocol/sdk/server/sse.js'; http.createServer(async (req, res) => { // ... // Creates a headless Playwright MCP server with SSE transport const connection = await createConnection({ browser: { launchOptions: { headless: true } } }); const transport = new SSEServerTransport('/messages', res); await connection.connect(transport); // ... }); ```
### Tools
Core automation - **browser_click** - Title: Click - Description: Perform click on a web page - Parameters: - `element` (string, optional): Human-readable element description used to obtain permission to interact with the element - `target` (string): Exact target element reference from the page snapshot, or a unique element selector - `doubleClick` (boolean, optional): Whether to perform a double click instead of a single click - `button` (string, optional): Button to click, defaults to left - `modifiers` (array, optional): Modifier keys to press - Read-only: **false** - **browser_close** - Title: Close browser - Description: Close the page - Parameters: None - Read-only: **false** - **browser_console_messages** - Title: Get console messages - Description: Returns all console messages - Parameters: - `level` (string): Level of the console messages to return. Each level includes the messages of more severe levels. Defaults to "info". - `all` (boolean, optional): Return all console messages since the beginning of the session, not just since the last navigation. Defaults to false. - `filename` (string, optional): File name to save the console messages to. Relative file names are resolved against the workspace root. If not provided, messages are returned as text. - Read-only: **true** - **browser_drag** - Title: Drag mouse - Description: Perform drag and drop between two elements - Parameters: - `startElement` (string, optional): Human-readable source element description used to obtain the permission to interact with the element - `startTarget` (string): Exact target element reference from the page snapshot, or a unique element selector - `endElement` (string, optional): Human-readable target element description used to obtain the permission to interact with the element - `endTarget` (string): Exact target element reference from the page snapshot, or a unique element selector - Read-only: **false** - **browser_drop** - Title: Drop files or data onto an element - Description: Drop files or MIME-typed data onto an element, as if dragged from outside the page. At least one of "paths" or "data" must be provided. - Parameters: - `element` (string, optional): Human-readable element description used to obtain permission to interact with the element - `target` (string): Exact target element reference from the page snapshot, or a unique element selector - `paths` (array, optional): Absolute paths to files to drop onto the element. - `data` (object, optional): Data to drop, as a map of MIME type to string value (e.g. {"text/plain": "hello", "text/uri-list": "https://example.com"}). - Read-only: **false** - **browser_emulate_media** - Title: Emulate media features - Description: Emulate CSS media features for the page, for example switch between the light and dark color scheme. Omitted parameters are left unchanged; null clears an override. - Parameters: - `colorScheme` (optional): Emulates the prefers-color-scheme media feature - `reducedMotion` (optional): Emulates the prefers-reduced-motion media feature - `forcedColors` (optional): Emulates the forced-colors media feature - `contrast` (optional): Emulates the prefers-contrast media feature - `media` (optional): Changes the CSS media type of the page - Read-only: **false** - **browser_evaluate** - Title: Evaluate JavaScript - Description: Evaluate JavaScript expression on page or element - Parameters: - `element` (string, optional): Human-readable element description used to obtain permission to interact with the element - `target` (string, optional): Exact target element reference from the page snapshot, or a unique element selector - `function` (string): () => { /* code */ } or (element) => { /* code */ } when element is provided - `filename` (string, optional): File name to save the result to. Relative file names are resolved against the workspace root. If not provided, result is returned as text. - Read-only: **false** - **browser_file_upload** - Title: Upload files - Description: Upload one or multiple files - Parameters: - `paths` (array, optional): The absolute paths to the files to upload. Can be single file or multiple files. If omitted, file chooser is cancelled. - Read-only: **false** - **browser_fill_form** - Title: Fill form - Description: Fill multiple form fields - Parameters: - `fields` (array): Fields to fill in - Read-only: **false** - **browser_find** - Title: Find in page snapshot - Description: Search the accessibility snapshot of the current page for text or a regular expression. Returns matching snapshot nodes with a few lines of surrounding context (like search snippets), each shown under its path from the root of the tree, which is cheaper than capturing the whole snapshot when you only need to locate an element and its ref. - Parameters: - `text` (string, optional): Plain text to search for in the page snapshot (case-insensitive substring match). Provide either text or regex, not both. > The README is long; the above is its first 40000 characters. Full content: https://github.com/microsoft/playwright-mcp
