## What it 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.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `MELTFLEX_API_KEY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
