base on Playwright MCP server ## 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. ### 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 or any other MCP client  ### Getting started First, install the Playwright MCP server with your client. A typical configuration looks like this: ```js { "mcpServers": { "playwright": { "command": "npx", "args": [ "@playwright/mcp@latest" ] } } } ``` [<img src="https://img.shields.io/badge/VS_Code-VS_Code?style=flat-square&label=Install%20Server&color=0098FF" alt="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) [<img alt="Install in VS Code Insiders" src="https://img.shields.io/badge/VS_Code_Insiders-VS_Code_Insiders?style=flat-square&label=Install%20Server&color=24bfa5">](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) <details><summary>Install in VS Code</summary> You can also install the Playwright MCP server using the VS Code CLI: ```bash # For VS Code code --add-mcp '{"name":"playwright","command":"npx","args":["@playwright/mcp@latest"]}' ``` After installation, the Playwright MCP server will be available for use with your GitHub Copilot agent in VS Code. </details> <details> <summary>Install in Cursor</summary> #### Click the button to install: [![Install MCP Server](https://cursor.com/deeplink/mcp-install-dark.svg)](https://cursor.com/install-mcp?name=playwright&config=eyJjb21tYW5kIjoibnB4IEBwbGF5d3JpZ2h0L21jcEBsYXRlc3QifQ%3D%3D) #### Or install manually: Go to `Cursor Settings` -> `MCP` -> `Add new MCP Server`.

They can be provided in the JSON configuration above, as a part of the `"args"` list:  ``` > npx @playwright/mcp@latest --help --allowed-origins <origins> semicolon-separated list of origins to allow the browser to request. Default is to allow all. --blocked-origins <origins> semicolon-separated list of origins to block the browser from requesting. Blocklist is evaluated before allowlist. If used without the allowlist, requests not matching the blocklist are still allowed. --block-service-workers block service workers --browser <browser> browser or chrome channel to use, possible values: chrome, firefox, webkit, msedge. --browser-agent <endpoint> Use browser agent (experimental). --caps <caps> comma-separated list of capabilities to enable, possible values: tabs, pdf, history, wait, files, install. Default is all. --cdp-endpoint <endpoint> CDP endpoint to connect to. --config <path> path to the configuration file. --device <device> device to emulate, for example: "iPhone 15" --executable-path <path> path to the browser executable. --headless run browser in headless mode, headed by default --host <host> host to bind server to. Default is localhost. Use 0.0.0.0 to bind to all interfaces. --ignore-https-errors ignore https errors --isolated keep the browser profile in memory, do not save it to disk. --image-responses <mode> whether to send image responses to the client. Can be "allow", "omit", or "auto". Defaults to "auto", which sends images if the client can display them. --no-sandbox disable the sandbox for all process types that are normally sandboxed. --output-dir <path> path to the directory for output files. --port <port> port to listen on for SSE transport. --proxy-bypass <bypass> comma-separated domains to bypass proxy, for example ".com,chromium.org,.domain.com" --proxy-server <proxy> specify proxy server, for example "http://myproxy:3128" or "socks5://myproxy:8080" --save-trace Whether to save the Playwright Trace of the session into the output directory. --storage-state <path> path to the storage state file for isolated sessions. --user-agent <ua string> specify user agent string --user-data-dir <path> path to the user data directory. If not specified, a temporary directory will be created. --viewport-size <size> specify browser viewport size in pixels, for example "1280, 720" --vision Run server that uses screenshots (Aria snapshots are used by default) ```  ### User profile You can run Playwright MCP with persistent profile like a regular browser (default), or in the isolated contexts for the testing sessions. **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}-profile # macOS - ~/Library/Caches/ms-playwright/mcp-{channel}-profile # Linux - ~/.cache/ms-playwright/mcp-{channel}-profile ``` **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}" ] } } } ``` ### 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 ``` <details> <summary>Configuration file schema</summary> ```typescript { // Browser configuration browser?: { // Browser type to use (chromium, firefox, or webkit) browserName?: 'chromium' | 'firefox' | 'webkit'; // Keep the browser profile in memory, do not save it to disk. isolated?: boolean; // Path to user data directory for browser profile persistence userDataDir?: string; // Browser launch options (see Playwright docs) // @see https://playwright.dev/docs/api/class-browsertype#browser-type-launch launchOptions?: { channel?: string; // Browser channel (e.g. 'chrome') headless?: boolean; // Run in headless mode executablePath?: string; // Path to browser executable // ... other Playwright launch options }; // Browser context options // @see https://playwright.dev/docs/api/class-browser#browser-new-context contextOptions?: { viewport?: { width: number, height: number }; // ... other Playwright context options }; // CDP endpoint for connecting to existing browser cdpEndpoint?: string; // Remote Playwright server endpoint remoteEndpoint?: string; }, // Server configuration server?: { port?: number; // Port to listen on host?: string; // Host to bind to (default: localhost) }, // List of enabled capabilities capabilities?: Array< 'core' | // Core browser automation 'tabs' | // Tab management 'pdf' | // PDF generation 'history' | // Browser history 'wait' | // Wait utilities 'files' | // File handling 'install' | // Browser installation 'testing' // Testing >; // Enable vision mode (screenshots instead of accessibility snapshots) vision?: boolean; // Directory for output files outputDir?: string; // Network configuration network?: { // List of origins to allow the browser to request.
