MeltFlex AI Overview

MeltFlex AI MCP server gives agents tools for photorealistic interior, exterior, furniture, video, and 3D generation from images or floorplans. It calls the public MeltFlex API using the user's API key, with image, video, and 3D generations charged to that account's credits. Use it for room redesigns, virtual staging, product-specific furniture placement, floorplan conversion, furniture modeling, or explorable room worlds. The repository also provides Markdown-based skills for agents that do not use MCP directly.
