Cloudflare Browser Rendering MCP server for AI agents

The Cloudflare Browser Rendering MCP Server provides a Model Context Protocol implementation that connects to Cloudflare's Browser Rendering API services. It enables you to retrieve HTML content, convert webpages to Markdown, and capture screenshots from any website through simple tool commands after authenticating with Cloudflare OAuth.

Available Tools

The server currently offers three main tools:

get_url_html_content: Retrieves the HTML content of the specified URL
get_url_markdown: Fetches the webpage content and converts it into Markdown format
get_url_screenshot: Captures a screenshot of the webpage (with optional viewport size specification)

Before using these tools, you must set an active account using the accounts_list and set_active_account commands.

Connecting to the Remote MCP Server

Using a Client with Native Support

If your MCP client directly supports remote MCP servers, simply enter the server URL:

https://browser.mcp.cloudflare.com

For example, this works with Cloudflare AI Playground.

Using a Client Without Native Support

For clients without built-in remote MCP support:

Install the mcp-remote package:
```
npm install mcp-remote
```

Create or update your client's configuration file with:

{
    "mcpServers": {
        "cloudflare": {
            "command": "npx",
            "args": ["mcp-remote", "https://browser.mcp.cloudflare.com/sse"]
        }
    }
}

Restart your MCP client
Complete the OAuth authentication flow in the browser window that opens
After successful authentication, the tools will become available

Usage Examples

Here are some example prompts to use with the tools:

Retrieving HTML Content

Get the HTML content of https://example.com.

Converting to Markdown

Convert https://example.com to Markdown.

Taking Screenshots

Take a screenshot of https://example.com.

Remember to set an active account first if you haven't already:

accounts_list
set_active_account [account-name-or-id]

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "cloudflare" '{"command":"npx","args":["mcp-remote","https://browser.mcp.cloudflare.com/sse"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cloudflare": {
            "command": "npx",
            "args": [
                "mcp-remote",
                "https://browser.mcp.cloudflare.com/sse"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "cloudflare": {
            "command": "npx",
            "args": [
                "mcp-remote",
                "https://browser.mcp.cloudflare.com/sse"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
