MeltFlex AI MCP Server

MeltFlex AI Skills

AI agent skills for photorealistic interior design via MeltFlex AI — restyle rooms, place real furniture, virtually stage, and re-theme spaces from a single photo. Works with Claude Code, Hermes, Cursor, Codex, and other AI agents that load Markdown-based skills or speak MCP.

Each user authenticates with their own MeltFlex API key; every generation is billed to their account credits. The skills call the public MeltFlex API directly, so there's nothing extra to install.

Install

Pick one. Each method sets up the skills for your agent.

npx skills — recommended, cross-agent

npx skills add MeltFlexDevs/skills

GitHub CLI (v2.90+)

gh skill install MeltFlexDevs/skills

Claude Code marketplace

Inside Claude Code:

/plugin marketplace add MeltFlexDevs/skills
/plugin install meltflex@meltflex

Setup script

Universal fallback:

git clone --depth 1 https://github.com/MeltFlexDevs/skills.git
cd skills
./setup

More options in INSTALL.md. Agent-driven install (paste into your agent): INSTALL_FOR_AGENTS.md.

Authenticate

You need an active subscription (any paid plan) — without one the key won't work. After subscribing at https://www.meltflexai.com/settings, open account settings → API Key under Profile, then Generate API Key (shown once — copy it):

Then expose it:

export MELTFLEX_API_KEY="mf_sk_xxxxxxxxxxxx"

Use with Hermes

Hermes (Nous Research) speaks MCP, so it runs MeltFlex through the meltflex-mcp server.

From the catalog (once merged into the Hermes catalog):

hermes mcp install meltflex

Manually — sign in once, then add the server to ~/.hermes/config.yaml:

npx -y meltflex-mcp auth login

mcp_servers:
  meltflex:
    command: npx
    args: ["-y", "meltflex-mcp"]

Start hermes chat (or run /reload-mcp in a session) to load the generate_interior and check_credits tools. Full guide: https://www.meltflexai.com/mcp.

Security

The skills never contain a key. Each user supplies their own mf_sk_ key via MELTFLEX_API_KEY; generations spend that user's own credits. Credits, auth, and rate limits are all enforced server-side. Never commit your key — revoke it anytime in settings.
