MeltFlex AI — Claude Code MCP server: what it does, how to install
Turns a room photo into a photorealistic interior, facade or garden redesign, and builds 3D furniture models or 3D worlds from the same photo.
claude mcp add meltflex -e MELTFLEX_API_KEY=<MELTFLEX_API_KEY> -- npx -y meltflex-mcpWhat MeltFlex AI does
MeltFlex AI talks to the public meltflexai.com API and gives an agent tools for reworking a space: changing a room's style, placing furniture, swapping floors, walls, stairs, doors or windows, redoing a kitchen or bathroom, or restyling a garden and facade. One mode turns a rough 3D draft into a photo, another edits only a masked region of the image. Beyond stills, the server can generate walkthrough videos, convert a furniture photo into a GLB model, turn a 2D floorplan into a 3D model or rendered picture, and turn a room photo into an explorable 3D world.
Calls go to /api/v1/generate or related endpoints with parameters for mode, resolution and quality level; the three 3D builds can return an HTTP 202 with a poll URL instead of an immediate result. Running any of this needs a personal MeltFlex API key, and that key only gets issued once there's an active paid subscription on the MeltFlex site, so a free account alone won't be enough.
The server runs through npx -y meltflex-mcp with MELTFLEX_API_KEY set in the environment. Image generations spend account credits and get refunded automatically if a job fails.
What it helps with
- restyle a room photo into a different interior look
- drop a specific furniture piece into a room photo at the right scale and color
- swap floors, walls, doors or windows on an existing photo
- convert a 2D floorplan into a 3D model or rendered picture
- build a GLB model of furniture from a product photo
Example prompts for the agent
- Restyle this living room photo into a Scandinavian look with /meltflex:design
- Place this armchair from the product photo into the room with /meltflex:furniture
- Turn this floorplan into a 3D model with /meltflex:3d
