Playwright Mcp

Playwright MCP

A Model Context Protocol (MCP) server that provides browser automation capabilities using Playwright. 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, Goose or any other MCP client

Getting started

  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": [
        "@playwright/mcp@latest"
      ]
    }
  }
}

  "playwright": {
    "command": "npx",
    "args": [
      "@playwright/mcp@latest"
    ]
  }
}

Amp CLI Setup:

Add via the amp mcp addcommand below

amp mcp add playwright -- npx @playwright/mcp@latest

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.

# 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.

{
  "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 extension/README.md for installation and setup instructions.

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:

npx @playwright/mcp@latest --config path/to/config.json

Configuration file schema

{
  // 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
    };

    allowedOrigins?: string[];

    // List of origins to block the browser to request. Origins matching both `allowedOrigins` and `blockedOrigins` will be blocked.
    blockedOrigins?: string[];
  };
 
  /**
   * Whether to send image responses to the client. Can be "allow" or "omit". 
   * Defaults to "allow".
   */
  imageResponses?: 'allow' | 'omit';
}

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.

npx @playwright/mcp@latest --port 8931

And then in MCP client config, set the url to the HTTP endpoint:

{
  "mcpServers": {
    "playwright": {
      "url": "http://localhost:8931/mcp"
    }
  }
}

Docker

NOTE: The Docker implementation only supports headless chromium at the moment.

{
  "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 \
  cli.js --headless --browser chromium --no-sandbox --port 8931

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

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);

  // ...
});
