Installation

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

        "https://bindings.mcp.cloudflare.com/mcp"
      ]
    }
  }
}

Deploying Your Own Cloudflare MCP Server

You can also deploy your own custom MCP server on Cloudflare Workers.

Create a new Worker project:

npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless
cd my-mcp-server

Install dependencies:
```
npm install
```
Start the development server:
```
npm start
```
Your MCP server will be running on http://localhost:8788/sse.
Deploy to Cloudflare:
```
npx wrangler@latest deploy
```

Custom Worker Deployment:

This Docker configuration assumes you have deployed your own Cloudflare Worker MCP server and are providing its URL.

Common Use Cases

1. Automated Infrastructure Management

Manage DNS records, firewall rules, and Workers deployments through natural language:

// Update DNS record
use_mcp_tool({
  server_name: "cloudflare",
  tool_name: "update_dns_record",
  arguments: {
    zone_id: "your-zone-id",
    record_id: "your-record-id",
    type: "A",
    name: "example.com",
    content: "192.0.2.1"
  }
});

2. Observability and Debugging

Query logs, analyze performance metrics, and debug Workers applications using AI agents:

// Get Worker errors
use_mcp_tool({
  server_name: "cloudflare",
  tool_name: "get_logs",
  arguments: {
    worker_name: "my-app-worker",
    log_level: "error",
    time_range: "24 hours"
  }
});

3. Content Delivery Optimization

Configure caching, image optimization, and other CDN settings:

// Purge cache for a URL
use_mcp_tool({
  server_name: "cloudflare",
  tool_name: "purge_cache",
  arguments: {
    zone_id: "your-zone-id",
    url: "https://www.example.com/image.jpg"
  }
});

4. Security Policy Enforcement

Update WAF rules, manage bot protection, and configure access policies:

// Block an IP address
use_mcp_tool({
  server_name: "cloudflare",
  tool_name: "update_waf_rule",
  arguments: {
    zone_id: "your-zone-id",
    rule_id: "your-rule-id",
    action: "block",
    filter: "ip.src eq 1.2.3.4"
  }
});

5. AI-Powered Development

Build and deploy AI applications on Cloudflare Workers, leveraging MCP for seamless integration:

// Deploy an AI Worker
use_mcp_tool({
  server_name: "cloudflare",
  tool_name: "deploy_worker",
  arguments: {
    name: "ai-inference-worker",
    script: "// AI inference logic here"
  }
});
