npm run build
node dist/index.js     # stdio transport for MCP

Claude Code Integration

Add to .mcp.json in your project root:

{
  "mcpServers": {
    "cloudflare": {
      "command": "node",
      "args": ["/path/to/mcp-cloudflare/dist/index.js"],
      "env": {
        "CLOUDFLARE_API_TOKEN": "your-api-token-here",
        "CLOUDFLARE_ACCOUNT_ID": "your-account-id"
      }
    }
  }
}

Configuration

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | CLOUDFLARE_API_TOKEN | Yes | — | Cloudflare API Token (with appropriate permissions) | | CLOUDFLARE_ACCOUNT_ID | No | — | Cloudflare Account ID (required for account-level operations) | | CLOUDFLARE_TIMEOUT | No | 30000 | Request timeout in milliseconds |

API Token Permissions

Create an API Token at dash.cloudflare.com/profile/api-tokens with the following permissions based on what you need:

• DNS: Zone > DNS > Edit
• Zone settings: Zone > Zone Settings > Edit
• Tunnels: Account > Cloudflare Tunnel > Edit
• WAF: Zone > Firewall Services > Edit
• Zero Trust: Account > Access: Apps and Policies > Edit
• Security events: Zone > Analytics > Read
• Workers KV: Account > Workers KV Storage > Edit
• Workers: Account > Worker Scripts > Edit
• R2: Account > R2 Storage > Edit

Multi-Zone Support

All zone-scoped tools accept a zone_id parameter that can be either:

• A 32-character hex zone ID (e.g., 00000000000000000000000000000001) — used directly
• A zone name / domain (e.g., example.com) — resolved automatically via the Cloudflare API

This allows managing multiple zones by name without needing to look up IDs manually.

Tools

Tools documentation is coming in v1 as tool modules are implemented. See docs/api-reference.md for the planned API endpoint mapping.
