## Cloudflare Playwright MCP
[](https://deploy.workers.cloudflare.com/?url=https://github.com/cloudflare/playwright-mcp/tree/main/cloudflare/example)
### Overview
This project leverages Playwright for automated browser testing and integrates with Cloudflare Workers, [Browser Rendering](https://developers.cloudflare.com/browser-rendering/) and [`@cloudflare/playwright`](https://github.com/cloudflare/playwright) for deployment.
### Build and Deploy
Follow these steps to set up and deploy the project:
1. Install dependencies:
```bash
npm ci
```
2. Build:
```bash
cd cloudflare
npm run build
```
3. Deploy to Cloudflare Workers:
```bash
cd cloudflare/example
npm ci
npx wrangler deploy
```
### Use with Cloudflare AI Playground
[Cloudflare playground AI](https://playground.ai.cloudflare.com/) is a great way to test MCP servers using LLM models available in Workers AI.
- Navigate to https://playground.ai.cloudflare.com/
- Ensure model is set to `llama-3.3-70b-instruct-fp8-fast`
- In **MCP Servers**, set **URL** to `https://[my-mcp-url].workers.dev/sse`
- Click **Connect**
- Status should update to **Connected** and it should list 14 available tools
You can now start to interact with the model, and it will run necessary tools to accomplish what was requested.
> [!TIP]
> For best results, give simple instructions consisting of one single action, e. g., "Create a new todo entry", "Go to cloudflare site", "Take a screenshot"
Example of a conversation:
| Role | Message |
|------|---------|
| **User** | Go to demo.playwright.dev/todomvc |
| **Assistant** | *runs browser_navigate tool*<br> The page has been navigated to https://demo.playwright.dev/todomvc/. The page title is "React • TodoMVC". The page snapshot shows the content of the page, including a heading, a textbox, and several links. |
| **User** | Create some todo entry |
| **Assistant** | *runs browser_type tool*<br> A new todo entry "Buy groceries" has been created. The page snapshot shows the updated content of the page, including the new todo entry. |
| **User** | Nice. Now create a todo in parrot style |
| **Assistant** | *runs browser_type tool*<br> A new todo entry "Polly wants a cracker" has been created in parrot style. The page snapshot shows the updated content of the page, including the new todo entry. |
| **User** | And create another todo in yoda style |
| **Assistant** | *runs browser_type tool*<br> A new todo entry "A walk, I must take" has been created in Yoda style. The page snapshot shows the updated content of the page, including the new todo entry. |
| **User** | Take a screenshot |
| **Assistant** | *runs browser_take_screenshot tool*<br>  A screenshot of the current page has been taken. The screenshot is in PNG format and is 56KB in size. |
| **User** | Now click the checkbox of the parrot todo entry |
| **Assistant** | *runs browser_clickt tool*<br> The checkbox of the parrot todo entry "Polly wants a cracker" has been clicked. The page snapshot shows the updated content of the page, with the checkbox now checked. |
| **User** | Take a screenshot |
| **Assistant** | *runs browser_take_screenshot tool*<br>  A screenshot of the current page has been taken. The screenshot is in PNG format and is 58KB in size. |
| **User** | Remove completed todo entries |
| **Assistant** | *runs browser_clickt tool*<br> The "Clear completed" button has been clicked. The page snapshot shows the updated content of the page, with the completed todo entry "Polly wants a cracker" removed. |
| **User** | Take a final screenshot |
| **Assistant** | *runs browser_take_screenshot tool*<br>  A final screenshot of the current page has been taken. The screenshot is in PNG format and is 50KB in size. |
### Use with Claude Desktop
As of now, [Claude Desktop](https://claude.ai/download) only supports local MCP servers. To use `playground-mcp` with Claude Desktop we make use of [mcp-remote](https://github.com/geelen/mcp-remote), a tool that proxies remote MCP servers and exposes them locally. Use the following configuration:
1. Open the configuration file for Claude Desktop.
2. Add the following JSON snippet under the `mcpServers` section:
```json
{
"mcpServers": {
"cloudflare-playwright-mcp": {
"command": "npx",
"args": [
"mcp-remote",
"https://[my-mcp-url].workers.dev/sse"
]
}
}
}
```
3. Save the configuration file and **restart** Claude Desktop to apply the changes.
This setup ensures that Claude Desktop can communicate with the Cloudflare Playwright MCP server.
Here's an example of a session opening the TODO demo app, adding "buy lemons" and doing a screenshot, taking advantage of playwright-mcp tools and Browser Rendering:
### Configure in VSCode
You can install the Playwright MCP server using the [VS Code CLI](https://code.visualstudio.com/docs/configure/command-line):
```bash
# For VS Code
code --add-mcp '{"name":"cloudflare-playwright","type":"sse","url":"https://[my-mcp-url].workers.dev/sse"}'
```
```bash
# For VS Code Insiders
code-insiders --add-mcp '{"name":"cloudflare-playwright","type":"sse","url":"https://[my-mcp-url].workers.dev/sse"}'
```
After installation, the Playwright MCP server will be available for use with your GitHub Copilot agent in VS Code.

### 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
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.
