Installation

Prerequisites

• Python 3.10 or higher
• uv installed
• A Cloudflare account with an API token

Quick Start with uv

1. Clone or create the project:

mkdir cloudflare-mcp-server
cd cloudflare-mcp-server

2. Install with uv:

uv pip install -e .

Or install from the directory:

uv pip install cloudflare-mcp-server

Alternative: Using pip

pip install -e .

Configuration

Getting Your Cloudflare Credentials

1. API Token (Required):

   • Go to Cloudflare Dashboard
   • Click "Create Token"
   • Use "Edit zone DNS" template or create a custom token with the permissions you need
   • Copy the token

2. Account ID (Optional, but required for KV operations):

   • Go to your Cloudflare dashboard
   • Select any website
   • Scroll down on the Overview page to find your Account ID

Environment Variables

Set the following environment variables:

export CLOUDFLARE_API_TOKEN="your_api_token_here"
export CLOUDFLARE_ACCOUNT_ID="your_account_id_here"  # Optional, needed for KV

Or create a .env file (see .env.example).

Claude Desktop Configuration

Add to your Claude Desktop config file:

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

Using uv (recommended):

{
  "mcpServers": {
    "cloudflare": {
      "command": "uv",
      "args": [
        "--directory",
        "/absolute/path/to/cloudflare-mcp-server",
        "run",
        "cloudflare-mcp-server"
      ],
      "env": {
        "CLOUDFLARE_API_TOKEN": "your_api_token_here",
        "CLOUDFLARE_ACCOUNT_ID": "your_account_id_here"
      }
    }
  }
}

Using Python directly:

{
  "mcpServers": {
    "cloudflare": {
      "command": "python",
      "args": ["-m", "cloudflare_mcp_server"],
      "env": {
        "CLOUDFLARE_API_TOKEN": "your_api_token_here",
        "CLOUDFLARE_ACCOUNT_ID": "your_account_id_here"
      }
    }
  }
}

Available Tools

Workers KV Operations

• list_kv_namespaces - List all KV namespaces
• read_kv_value - Read a value from KV storage
• write_kv_value - Write a key-value pair to KV
• delete_kv_value - Delete a key from KV

For detailed documentation on each tool, see EXAMPLES.md.

Development

Using uv for Development

# Install in development mode with dev dependencies
uv pip install -e ".[dev]"

# Run the server directly
uv run cloudflare-mcp-server

# Run tests (when implemented)
uv run pytest

# Format code with ruff
uv run ruff format src/

# Lint code
uv run ruff check src/

Usage Examples

Example 1: List Your Zones

Ask Claude:

"Show me all my Cloudflare zones"

Example 2: Create a DNS Record

Ask Claude:

"Create an A record for api.example.com pointing to 192.0.2.100 with proxy enabled"

Example 3: Purge Cache

Ask Claude:

"Clear the cache for https://example.com/style.css"

For more examples, see EXAMPLES.md.

API Permissions

Your Cloudflare API token needs appropriate permissions based on what operations you want to perform:

Minimum Permissions:

• Zone - Zone - Read (for listing zones)
• Zone - DNS - Edit (for DNS operations)

Additional Permissions for Advanced Features:

• Account - Workers KV Storage - Edit (for KV operations)
• Zone - Cache Purge - Purge (for cache operations)
• Zone - Analytics - Read (for analytics)

Troubleshooting

Common Issues

1. "CLOUDFLARE_API_TOKEN environment variable is required"

   • Make sure you've set the environment variable
   • Check your Claude Desktop config has the correct token in the env section

2. "Account ID is required"

   • Set CLOUDFLARE_ACCOUNT_ID environment variable for KV operations
   • Or pass account_id parameter directly in tool calls

3. uv command not found

   • Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh
   • Or use pip as an alternative

4. Module not found errors

   • Make sure you installed the package: uv pip install -e .
   • Check you're in the right directory

Why uv?

This project uses uv because it's:

• ⚡ 10-100x faster than pip
• 🔒 More reliable with better dependency resolution
• 🎯 Simpler - one tool for everything
• 🐍 Modern - built in Rust, designed for Python

Security Notes

• Never commit your API token to version control
• Store tokens securely using environment variables
• Use API tokens instead of API keys (they're more secure and can be scoped)
• Regularly rotate your API tokens
• Use the minimum required permissions for your token
