MCP Servers

Playwright MCP Server

Enables browser automation and web interaction through structured accessibility snapshots using Playwright. Supports clicking, typing, navigation, form filling, and other web actions without requiring screenshots or vision models.

README

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

First, install the Playwright MCP server with your client.

Standard config works in most of the tools:

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

<details> <summary>Claude Code</summary>

Use the Claude Code CLI to add the Playwright MCP server:

claude 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

<details> <summary>Configuration file schema</summary>

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"
    }
  }
}

<details> <summary>Docker</summary>

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 .
