# Playwright Record MCP
Playwright Record MCP is a Model Context Protocol (MCP) server that provides browser automation capabilities using [Playwright](https://playwright.dev/). This server adds video recording functionality to record browser interactions. It enables LLMs (Large Language Models) to interact with web pages through structured accessibility snapshots, without requiring screenshots or visual 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.
- **Video recording**: Ability to record browser interactions as video.
## Use Cases
- Web navigation and form-filling
- Data extraction from structured content
- LLM-driven automated testing
- General-purpose browser interaction for agents
- Recording and analyzing browser interactions
## Installation
### Installation via NPM
```bash
npm install @playwright/record-mcp
```
Or
```bash
npx @playwright/record-mcp
```
### Configuration Example
#### NPX
```json
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": [
"@playwright/record-mcp@latest"
]
}
}
}
```
### Installation in VS Code
You can install the Playwright Record MCP server using VS Code CLI:
```bash
# For VS Code
code --add-mcp '{"name":"playwright","command":"npx","args":["@playwright/record-mcp@latest"]}'
```
```bash
# For VS Code Insiders
code-insiders --add-mcp '{"name":"playwright","command":"npx","args":["@playwright/record-mcp@latest"]}'
```
After installation, the Playwright Record MCP server will be available for use with your GitHub Copilot agent in VS Code.
## CLI Options
The Playwright Record MCP server supports the following command-line options:
- `--browser <browser>`: Browser or Chrome channel to use. Possible values:
- `chrome`, `firefox`, `webkit`, `msedge`
- Chrome channels: `chrome-beta`, `chrome-canary`, `chrome-dev`
- Edge channels: `msedge-beta`, `msedge-canary`, `msedge-dev`
- Default: `chrome`
- `--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
- `--executable-path <path>`: Path to the browser executable
- `--headless`: Run browser in headless mode (headed by default)
- `--port <port>`: Port to listen on for SSE transport
- `--user-data-dir <path>`: Path to the user data directory
- `--vision`: Run server that uses screenshots (Aria snapshots are used by default)
- `--record`: Record browser interactions as video (new feature)
- `--record-path <path>`: Path to save recording files (default: ./recordings)
- `--record-format <format>`: Recording format, possible values: mp4, webm (default: mp4)
## User Data Directory
Playwright Record MCP will launch the browser with a new profile, located at:
- Windows: `%USERPROFILE%\AppData\Local\ms-playwright\mcp-chrome-profile`
- macOS: `~/Library/Caches/ms-playwright/mcp-chrome-profile`
- Linux: `~/.cache/ms-playwright/mcp-chrome-profile`
All login information will be stored in that profile; you can delete it between sessions if you'd like to clear the offline state.
## Running Headless Browser (Browser without GUI)
This mode is useful for background or batch operations.
```json
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": [
"@playwright/record-mcp@latest",
"--headless"
]
}
}
}
```
## Using Video Recording
To use the video recording feature, use the `--record` flag:
```json
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": [
"@playwright/record-mcp@latest",
"--record"
]
}
}
}
```
To specify the recording file save path:
```json
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": [
"@playwright/record-mcp@latest",
"--record",
"--record-path", "./my-recordings"
]
}
}
}
```
To specify the recording format:
```json
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": [
"@playwright/record-mcp@latest",
"--record",
"--record-format", "webm"
]
}
}
}
```
## Running Headed Browser on Linux without DISPLAY
When running a headed browser on a system without a display or from worker processes of IDEs,
run the MCP server from an environment with DISPLAY and pass the `--port` flag to enable SSE transport.
```bash
npx @playwright/record-mcp@latest --port 8931
```
Then, in the MCP client config, set the `url` to the SSE endpoint:
```json
{
"mcpServers": {
"playwright": {
"url": "http://localhost:8931/sse"
}
}
}
```
## Docker
**NOTE:** The Docker implementation currently only supports headless Chromium.
```json
{
"mcpServers": {
"playwright": {
"command": "docker",
"args": ["run", "-i", "--rm", "--init", "mcp/playwright-record"]
}
}
}
```
To build with Docker:
```bash
docker build -t mcp/playwright-record .
```
## Tool Modes
The tools are available in two modes:
1. **Snapshot Mode** (default): Uses accessibility snapshots for better performance and reliability
2. **Vision Mode**: Uses screenshots for visual-based interactions
To use Vision Mode, add the `--vision` flag when starting the server:
```json
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": [
"@playwright/record-mcp@latest",
"--vision"
]
}
}
}
```
Vision Mode works best with computer use models that are able to interact with elements using X-Y coordinate space, based on the provided screenshot.
## Programmatic Usage with Custom Transports
```javascript
import http from 'http';
import { createServer } from '@playwright/record-mcp';
import { SSEServerTransport } from '@modelcontextprotocol/sdk/server/sse.js';
http.createServer(async (req, res) => {
// ...
// Creates a headless Playwright Record MCP server with SSE transport
const mcpServer = await createServer({ headless: true, record: true });
const transport = new SSEServerTransport('/messages', res);
await mcpServer.connect(transport);
// ...
});
```
