## Playwright MCP
|
||||
|
||||
This package is experimental and not yet ready for production use.
|
||||
It is a subject to change and will not respect semver versioning.
|
||||
|
||||
### Example config
|
||||
|
||||
```js
|
||||
{
|
||||
"mcpServers": {
|
||||
"playwright": {
|
||||
"command": "npx",
|
||||
"args": [
|
||||
"@playwright/mcp",
|
||||
"--headless"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Running headed browser (Browser with GUI).
|
||||
|
||||
```js
|
||||
{
|
||||
"mcpServers": {
|
||||
"playwright": {
|
||||
"command": "npx",
|
||||
"args": [
|
||||
"@playwright/mcp"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Running headed browser on Linux
|
||||
|
||||
When running headed browser on system w/o display or from worker processes of the IDEs,
|
||||
you can run Playwright in a client-server manner. You'll run the Playwright server
|
||||
from environment with the DISPLAY
|
||||
|
||||
```sh
|
||||
npx playwright run-server
|
||||
```
|
||||
|
||||
And then in MCP config, add following to the `env`:
|
||||
|
||||
```js
|
||||
{
|
||||
"mcpServers": {
|
||||
"playwright": {
|
||||
"command": "npx",
|
||||
"args": [
|
||||
"@playwright/mcp"
|
||||
],
|
||||
"env": {
|
||||
// Use the endpoint from the output of the server above.
|
||||
"PLAYWRIGHT_WS_ENDPOINT": "ws://localhost:<port>/"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 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:
|
||||
|
||||
```js
|
||||
{
|
||||
"mcpServers": {
|
||||
"playwright": {
|
||||
"command": "npx",
|
||||
"args": [
|
||||
"@playwright/mcp",
|
||||
"--vision"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Vision Mode works best with the computer use models that are able to interact with elements using
|
||||
X Y coordinate space, based on the provided screenshot.
