Playwright Tools for MCP
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"
]
}
}
}Use the Claude Code CLI to add the Playwright MCP server:
claude mcp add playwright npx @playwright/mcp@latestFollow the MCP install guide, use the standard config above.
Click the button to install:
Or install manually:
Go to Cursor Settings -> MCP -> Add new MCP Server. Name to your liking, use command type with the command npx @playwright/mcp. You can also verify config or add command like arguments via clicking Edit.
Follow the MCP install guide, use the standard config above.
Click the button to install:
Or install manually:
Go to Advanced settings -> Extensions -> Add custom extension. Name to your liking, use type STDIO, and set the command to npx @playwright/mcp. Click "Add Extension".
Click the button to install:
Or install manually:
Go to Program in the right sidebar -> Install -> Edit mcp.json. Use the standard config above.
Open Qodo Gen chat panel in VSCode or IntelliJ → Connect more tools → + Add new MCP → Paste the standard config above.
Click Save.
Click the button to install:
Or install manually:
Follow the MCP install guide, use the standard config above. You can also install the Playwright MCP server using the VS Code CLI:
# 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.
Follow Windsurf MCP documentation. Use the standard config above.
Configuration
Playwright MCP server supports following arguments. 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.
--caps <caps> comma-separated list of additional capabilities
to enable, possible values: vision, pdf.
--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" or "omit", Defaults to "allow".
--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-session Whether to save the Playwright MCP session into
the output directory.
--save-trace Whether to save the Playwright Trace of the
session into the output directory.
--span-size <size> Size of each snapshot span in characters. Use -1
to disable pagination and show complete snapshot.
Defaults to 2000.
--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"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.
# Windows
%USERPROFILE%\AppData\Local\ms-playwright\mcp-{channel}-profile
# macOS
- ~/Library/Caches/ms-playwright/mcp-{channel}-profile
# Linux
- ~/.cache/ms-playwright/mcp-{channel}-profileIsolated
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}"
]
}
}
}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{

}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 8931And then in MCP client config, set the url to the HTTP endpoint:
{
"mcpServers": {
"playwright": {
"url": "http://localhost:8931/mcp"
}
}
}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"]
}
}
}You can build the Docker image yourself.
docker build -t mcr.microsoft.com/playwright/mcp .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.sever.connect(transport);
// ...
