Cloudflare API MCP server for AI agents

This MCP server provides an interface for agents like Cursor to interact with the Cloudflare REST API through the Model Control Protocol. It allows you to manage Cloudflare resources programmatically using an agent as your assistant.

Installation

Follow these steps to set up the Cloudflare API MCP server:

Run the automated install script to clone and deploy the MCP server to your Cloudflare account:

bun create mcp --clone https://github.com/zueai/cloudflare-api-mcp

Open Cursor and navigate to Cursor Settings -> MCP -> Add new MCP server, then paste the command that was copied to your clipboard.
Upload your Cloudflare API credentials as worker secrets:

bunx wrangler secret put CLOUDFLARE_API_KEY
bunx wrangler secret put CLOUDFLARE_API_EMAIL

Usage

Available Tools

The MCP server provides various tools to interact with Cloudflare's API. Each method in the MyWorker class represents an available tool that your agent can use.

Managing DNS Records

You can create DNS records using the MCP server. For example:

createDNSRecord(zoneId, name, content, type, comment, proxied)

Where:

zoneId: The ID of the zone to create the record in
name: The name of the DNS record
content: The content of the DNS record
type: The type of DNS record (CNAME, A, TXT, or MX)
comment: Optional comment for the DNS record
proxied: Optional boolean indicating whether to proxy the record through Cloudflare

Local Development

If you need to develop locally, add your Cloudflare credentials to the .dev.vars file:

CLOUDFLARE_API_KEY=<your-cloudflare-api-key>
CLOUDFLARE_API_EMAIL=<your-cloudflare-api-email>

Deploying Updates

To deploy changes to your MCP server:

Run the deploy script:

bun run deploy

Reload your Cursor window to see the newly added tools.

Creating Custom Tools

You can extend the functionality by adding new methods to the MyWorker class in src/index.ts. Each function automatically becomes an MCP tool available to your agent.

When creating new tools, use proper JSDoc comments:

/**
 * Create a new DNS record in a zone.
 * @param zoneId {string} The ID of the zone to create the record in.
 * @param name {string} The name of the DNS record.
 * @param content {string} The content of the DNS record.
 * @param type {string} The type of DNS record (CNAME, A, TXT, or MX).
 * @param comment {string} Optional comment for the DNS record.
 * @param proxied {boolean} Optional whether to proxy the record through Cloudflare.
 * @return {object} The created DNS record.
 */

The JSDoc format is important as:

The first line becomes the tool's description
@param tags define parameters with types and descriptions
@return tag specifies what the tool returns

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-api-mcp" '{"command":"bunx","args":["cloudflare-api-mcp"]}'

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-api-mcp": {
            "command": "bunx",
            "args": [
                "cloudflare-api-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 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-api-mcp": {
            "command": "bunx",
            "args": [
                "cloudflare-api-mcp"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
