GPT-5 Multimodal Tool Integration for Figures

Implement an 'Image Analysis Agent' that uses GPT-5 (or a specialized VLM integrated with GPT-5) to analyze a base64 encoded patent figure. This agent should extract key features, objects, and their relationships described in the image. Use MCP to mock calling a 'Getty Images API' or similar service if GPT-5's multimodal capabilities are not sufficient for complex diagram interpretation. The output should be structured textual descriptions suitable for feeding into the graph RAG.
