Outsource MCP

Instructions

Delegate image generation to an external AI model. Use this when you need to create
visual content.

Args:
    provider: The AI provider to use (currently only "openai" is supported)
    model: The image model to use ("dall-e-3" for high quality, "dall-e-2" for faster/cheaper)
    prompt: A detailed description of the image you want to generate

Returns:
    The URL of the generated image, which can be shared with users or used in responses

Example usage:
    For high-quality images: provider="openai", model="dall-e-3", prompt="A photorealistic rendering of..."
    For quick concepts: provider="openai", model="dall-e-2", prompt="A simple sketch showing..."

Note: Only OpenAI currently supports image generation. Other providers will return an error.

Implementation Reference

• server.py:111-175 (handler)

  The async handler function for the 'outsource_image' tool, registered via @mcp.tool(). It delegates image generation to OpenAI's DALL-E models (dall-e-3 or dall-e-2), returning the generated image URL. Supports only OpenAI provider currently, with detailed error handling.
