Symbol Image Generation MCP Server

A Model Context Protocol (MCP) server that exposes a tool for generating beautiful, stylized 3D claymorphic/glassmorphic symbol images (such as rockets, padlocks, badges) and automatically removing their background via the remove.bg API.

Features

• Exposes the generate_symbol_image tool to MCP clients (like Claude Desktop).

• Auto-constructs a custom 3D isometric claymorphic/glassmorphic prompt matching your corporate UI aesthetics.

• Dynamically generates images using Google AI Studio (Imagen 3), Stability AI (SD3/Ultra), or OpenAI (DALL-E 3) based on configured API keys.

• Transparently removes background using the remove.bg API.

• Saves the final high-fidelity transparent PNG.

Installation

1. Navigate to the server folder:

   cd c:/Users/Tateo/my-project/symbol-image-mcp

Configuration

The server reads API keys from environment variables. Set at least one image generation API key (Google Imagen is preferred and checked first):

Integrating with Claude Desktop

To add this server to your Claude Desktop client, edit your configuration file located at: %APPDATA%\Claude\claude_desktop_config.json

Add the server to the mcpServers object:

{
  "mcpServers": {
    "symbol-image-mcp": {
      "command": "node",
      "args": ["c:/Users/Tateo/my-project/symbol-image-mcp/index.js"],
      "env": {
        "GEMINI_API_KEY": "YOUR_GEMINI_API_KEY_HERE",
        "STABILITY_API_KEY": "YOUR_STABILITY_API_KEY_HERE",
        "OPENAI_API_KEY": "YOUR_OPENAI_API_KEY_HERE"
      }
    }
  }
}

Restart Claude Desktop after updating the configuration.

Development and Testing

You can start the server locally in stdio transport mode:

node index.js

The server will start listening for JSON-RPC messages on standard input/output.
