Cloudflare MCP server

Cloudflare's Model Context Protocol (MCP) servers enable you to connect to Cloudflare's services from MCP clients like Cursor or Claude, allowing you to manage your Cloudflare account through natural language commands. These servers help you read configurations, process information, get suggestions, and implement changes across Cloudflare's range of services including application development, security, and performance.

Available MCP Servers

Cloudflare offers multiple specialized MCP servers:

• Documentation server: Get up-to-date reference information
• Workers Bindings server: Build Workers applications with storage, AI, and compute primitives
• Workers Builds server: Manage your Cloudflare Workers Builds
• Observability server: Debug and analyze application logs and analytics
• Radar server: Access global Internet traffic insights and URL scans
• Container server: Create sandbox development environments
• Browser rendering server: Fetch web pages, convert to markdown, and take screenshots
• Logpush server: Get summaries for Logpush job health
• AI Gateway server: Search logs and analyze prompts/responses
• AutoRAG server: List and search documents on your AutoRAGs
• Audit Logs server: Query audit logs and generate reports
• DNS Analytics server: Optimize DNS performance and troubleshoot issues
• Digital Experience Monitoring server: Get insights on critical applications
• Cloudflare One CASB server: Identify security misconfigurations in SaaS applications
• GraphQL server: Access analytics data using Cloudflare's GraphQL API

Connecting to MCP Servers

Using MCP Clients with Native Support

If your MCP client directly supports remote MCP servers (like Cloudflare AI Playground), you can enter the server URL within the client interface.

Using Clients Without Native Support

For clients without built-in support, set up a configuration file using mcp-remote:

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

Using with OpenAI Responses API

To use Cloudflare's MCP servers with OpenAI's Responses API:

1. Create a user API token (not an Account API token) with the required permissions
2. Go to the Cloudflare dashboard at https://dash.cloudflare.com/profile/api-tokens
3. Set appropriate permissions based on which MCP server you're using

For example, the Browser Rendering MCP server requires specific permissions that you can configure in your token settings.

Troubleshooting

Context Length Limitations

If you see a message like "Claude's response was interrupted...", the AI likely hit its context-length limit. To avoid this:

• Be specific and keep queries concise
• Break large requests into smaller tool calls to keep responses short

Service Requirements

Some features may require a paid Cloudflare Workers plan. Ensure your Cloudflare account has the necessary subscription level for the features you intend to use.

How to add this MCP server to 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 > MCP and click "Add new global MCP server".

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

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

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 explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
