cf-mcp-gateway 0.1.2

Centralized MCP Gateway for Cloudflare services

Cloudflare MCP Gateway

A centralized MCP (Model Context Protocol) gateway that aggregates multiple Cloudflare MCP services into a single unified server. Configure which services you need via environment variables and access them all through one MCP connection.

Features

• Unified Access: Single MCP server for multiple Cloudflare services
• Configurable Services: Enable only the services you need via ENABLED_SERVICES
• Dual Transport Support: Works with both stdio (Claude Desktop) and streamable HTTP (web clients)
• Tool Namespacing: Automatic prefixing prevents tool name collisions (e.g., kv_get, r2_list)
• Graceful Degradation: Continues operating if some upstream services are unavailable

Supported Services

Service ID	Name	Description
docs	Documentation	Cloudflare documentation reference and search
bindings	Workers Bindings	Storage, AI, and compute primitives for Workers
builds	Workers Builds	Deployment insights and management
observability	Observability	Logs and analytics debugging
radar	Radar	Internet traffic insights and URL scanning
browser	Browser Rendering	Web page fetching, markdown conversion, screenshots
ai-gateway	AI Gateway	Prompt/response log search and analysis
d1	D1	Serverless SQL database operations
kv	KV	Key-value storage operations
r2	R2	Object storage operations

Installation

# Using pip
pip install cf-mcp-gateway

# Using uv
uv pip install cf-mcp-gateway

Quick Start

1. Get Cloudflare Credentials

You'll need:

• API Token: Create one at Cloudflare Dashboard
• Account ID: Found in your Cloudflare dashboard URL or account settings

2. Configure Environment

Create a .env file or set environment variables:

# Required
CLOUDFLARE_API_TOKEN=your-api-token
CLOUDFLARE_ACCOUNT_ID=your-account-id
ENABLED_SERVICES=docs,kv,r2

# Optional
TRANSPORT=stdio  # or streamable-http
LOG_LEVEL=info

3. Run the Gateway

# Using the CLI
cf-mcp-gateway

# Or as a Python module
python -m cf_mcp_gateway

Usage with MCP Clients

Claude Desktop

Add to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "cloudflare": {
      "command": "python",
      "args": ["-m", "cf_mcp_gateway"],
      "env": {
        "CLOUDFLARE_API_TOKEN": "your-api-token",
        "CLOUDFLARE_ACCOUNT_ID": "your-account-id",
        "ENABLED_SERVICES": "docs,kv,r2,d1",
        "TRANSPORT": "stdio"
      }
    }
  }
}

Cursor

Add to your Cursor MCP settings:

{
  "mcpServers": {
    "cloudflare": {
      "command": "cf-mcp-gateway",
      "env": {
        "CLOUDFLARE_API_TOKEN": "your-api-token",
        "CLOUDFLARE_ACCOUNT_ID": "your-account-id",
        "ENABLED_SERVICES": "docs,bindings,observability"
      }
    }
  }
}

Streamable HTTP (Remote/Web Access)

Start the gateway with HTTP transport:

CLOUDFLARE_API_TOKEN=xxx \
CLOUDFLARE_ACCOUNT_ID=yyy \
ENABLED_SERVICES=docs,kv,r2 \
TRANSPORT=streamable-http \
GATEWAY_HOST=0.0.0.0 \
GATEWAY_PORT=3000 \
cf-mcp-gateway

The server exposes:

• POST /mcp - MCP JSON-RPC endpoint
• GET /health - Health check endpoint

Configuration Reference

Required Environment Variables

Variable	Description
CLOUDFLARE_API_TOKEN	Your Cloudflare API token
CLOUDFLARE_ACCOUNT_ID	Your Cloudflare account ID
ENABLED_SERVICES	Comma-separated list of service IDs to enable

Optional Environment Variables

Variable	Default	Description
TRANSPORT	stdio	Transport mode: stdio or streamable-http
GATEWAY_HOST	0.0.0.0	HTTP bind host (streamable-http only)
GATEWAY_PORT	3000	HTTP port (streamable-http only)
CORS_ORIGINS	``	Allowed CORS origins, comma-separated
LOG_LEVEL	info	Logging level: debug, info, warning, error

Tool Naming Convention

Tools from upstream services are prefixed with their service ID to avoid collisions:

• kv_get - Get value from KV
• kv_put - Put value to KV
• r2_list - List R2 objects
• r2_get - Get R2 object
• docs_search - Search Cloudflare documentation
