MeltFlex MCP

Generate interiors from any AI agent

Connect your agent

Pick your MCP client:

Add the MeltFlex server with one command:

claude mcp add meltflex -- npx -y meltflex-mcp

Then sign in with your API key:

npx -y meltflex-mcp auth mf_sk_xxxxxxxxxxxx

You can also authenticate the CLI directly: meltflex auth mf_sk_….

Where to find your API key

You need an active subscription (any paid plan). Once subscribed, open your account settings and click API Key under Profile:

Then click Generate API Key. The key is shown only once — copy it immediately.

Then just ask in chat — e.g. “Here's my living room /Users/me/room.jpg — redesign it in warm minimalist style.”

Overview

Connect MeltFlex to your workflow and redesign rooms directly from your prompts. The MeltFlex MCP server exposes generation as tools any agent can call.

Each user connects their own MeltFlex account; every generation is billed to that account's credits. The server is a thin client over the MeltFlex API.

FAQ

Do I need an API key?

Yes. Each user authenticates with their own MeltFlex API key (any active subscription). Generate one in account settings, then pass it via the MELTFLEX_API_KEY env block or meltflex auth.

Whose credits are used?

Your own. The server runs under your account and every generation is billed to your account credits — 10 per image.

Is it safe?

The MCP layer adds no new attack surface: anything it can do is already doable with a request to the same API using the same key. Credit limits, refunds and rate limits all live server-side.

My client isn't listed — can I still use it?

Any client that speaks the Model Context Protocol works. Use the standard command / args / env config shown above.

Where do generated images go?

The generate_interior tool saves the result to disk and returns the file path. Pass output_path to control the location.
