Splitting the work into 15 modes matters more than it sounds: swapping a floor, restyling stairs or redesigning a bathroom are different prompts against the same endpoint, so you are not fighting a general model into a narrow edit. The furniture skill is the sharper case — pass the actual product images and the result keeps their colours and proportions instead of approximating them.
MeltFlex's agent bundle for photorealistic interior and exterior design. It ships two skills — a general design skill with 15 prompt-driven modes and a furniture skill that places specific real products into a room photo — and an MCP server for clients that speak MCP. Everything runs against the public MeltFlex API with your own key, billed to your credits.
- generate_interior — the design call behind the 15 modes: restyle, virtual_staging, layout_boost, declutter, exterior, garden, wall_texture, floor_restyle, stairs, doors, windows, kitchen, bathroom, photo_to_render and seasonal, each the same endpoint with a mode-tuned prompt
- generate_video — a cinematic walkthrough rather than a still, at 100–150 credits
- floorplan_to_3d — a 2D floorplan turned into a 3D model, at 10 credits
- check_credits — the remaining credit balance
- The furniture skill — place up to 10 specific real products into a room photo, matching their colours, materials and proportions rather than inventing lookalikes
An active paid MeltFlex plan — a free trial key will not work. Generate the key under account settings (it starts with mf_sk_, and is shown once) and export it as MELTFLEX_API_KEY. Install the skills with npx skills add MeltFlexDevs/skills, gh skill install, or the Claude Code marketplace; for MCP clients, sign in once with npx -y meltflex-mcp auth login and add the server. A still generation costs 10 credits and is refunded automatically if it fails.
One command plus a key — npx -y meltflex-mcp, then supply credentials
