Cloudflare Edge Services MCP server

This Cloudflare MCP server provides a standardized image generation service built with Model Context Protocol (MCP) and Cloudflare Workers. The implementation offers a ready-to-use module for generating images at the edge.

Installation Requirements

Before you begin, make sure you have:

• Node.js 18 or newer
• Wrangler CLI
• NPM (or PNPM as shown in examples)

Setting Up the Server

Installation Steps

1. Install the required dependencies:

pnpm install

2. Configure your environment variables:

cp .env.example .env

3. Deploy the Worker to Cloudflare:

pnpm deploy

Using the Image Generation API

The MCP server provides a standardized interface for image generation through the Flux-1-Schnell model.

Configuration Example

To configure an MCP server for image generation, use the following JSON configuration:

{
  "mcpServers": {
    "generateImage": {
      "command": "/Users/zhangxudong/Gits/turinhub/cf-mcp-server/mcp-image-generation/node_modules/.bin/workers-mcp",
      "args": [
        "run",
        "generateImage",
        "https://mcp-image-generation.turinhub.com",
        "/Users/zhangxudong/Gits/turinhub/cf-mcp-server/mcp-image-generation"
      ],
      "env": {}
    }
  }
}

Parameters

The image generation API accepts the following parameters:

Parameter	Type	Constraints	Description
prompt	string	1-500 characters	English description prompt
steps	number	4 ≤ steps ≤ 8	Number of generation iterations

Technical Specifications

• Supported Steps Range: 4-8 steps
• Response Format: Base64-encoded PNG image
• Deployment Method: Cloudflare Workers

Testing Your MCP Implementation

You can test your MCP implementation using the inspector tool:

npx @modelcontextprotocol/inspector

This allows you to verify that your server correctly implements the Model Context Protocol standards and properly handles image generation requests.

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 "generateImage" '{"command":"/Users/zhangxudong/Gits/turinhub/cf-mcp-server/mcp-image-generation/node_modules/.bin/workers-mcp","args":["run","generateImage","https://mcp-image-generation.turinhub.com","/Users/zhangxudong/Gits/turinhub/cf-mcp-server/mcp-image-generation"],"env":[]}'

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": {
        "generateImage": {
            "command": "/Users/zhangxudong/Gits/turinhub/cf-mcp-server/mcp-image-generation/node_modules/.bin/workers-mcp",
            "args": [
                "run",
                "generateImage",
                "https://mcp-image-generation.turinhub.com",
                "/Users/zhangxudong/Gits/turinhub/cf-mcp-server/mcp-image-generation"
            ],
            "env": []
        }
    }
}

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": {
        "generateImage": {
            "command": "/Users/zhangxudong/Gits/turinhub/cf-mcp-server/mcp-image-generation/node_modules/.bin/workers-mcp",
            "args": [
                "run",
                "generateImage",
                "https://mcp-image-generation.turinhub.com",
                "/Users/zhangxudong/Gits/turinhub/cf-mcp-server/mcp-image-generation"
            ],
            "env": []
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
