Pixfaro MCP — image generation MCP server for every image model

One MCP connection, one prepaid balance, every major image model — Nano Banana, Gemini today, GPT Image next (visible as "coming soon" in list_models). Pixfaro holds the provider accounts, keys, retries and format differences; your agent just asks for an image.

Works with Claude Desktop, Claude Code, Cursor, Windsurf, and any MCP client.

Quickstart (≈1 minute)

1. Get an API key at pixfaro.com and top up (no subscription).
2. Add the server to your MCP client config:

{
  "mcpServers": {
    "pixfaro": {
      "command": "npx",
      "args": ["-y", "@pixfaro/mcp"],
      "env": { "PIXFARO_KEY": "pf_live_…" }
    }
  }
}

3. Ask your agent for an image. That's it.

For Claude Code:

claude mcp add pixfaro -e PIXFARO_KEY=pf_live_… -- npx -y @pixfaro/mcp

Remote server (no install, OAuth)

On claude.ai, Claude Desktop, or any client that speaks streamable HTTP, add the remote server instead — no npm, no key in a config file:

https://mcp.pixfaro.com/mcp

The client runs the OAuth flow; you sign in with your Pixfaro account. Clients without OAuth can pass an API key instead: Authorization: Bearer pf_live_….

Tools

Tool	What it does
generate_image	prompt → hosted image URL (+cost and balance in the reply)
edit_image	natural-language edit of a previous generation by its img_… id
list_models	models with price, latency, and what each is best for
get_balance	current prepaid balance

Replies carry a hosted URL, never base64 — your agent's context stays small.

Both generation tools accept aspect_ratio (e.g. "16:9", "9:16"). Edits keep the source image's shape when you omit it — pass one only to reshape.

CLI

The same package family ships an unscoped CLI for scripts, CI, and pipelines:

export PIXFARO_KEY=pf_live_…
npx pixfaro gen "a lighthouse at night, minimal flat style" -a 16:9 -o cover.png
npx pixfaro models
npx pixfaro balance
npx pixfaro edit img_8f2a… "make the sky darker" -o v2.png

Environment

Variable	Meaning
PIXFARO_KEY	your API key (pf_live_…) — required for everything except models
PIXFARO_API_URL	endpoint override (default https://api.pixfaro.com)

What this repo is

The thin open client over the Pixfaro API: the MCP server (@pixfaro/mcp) and the pixfaro CLI share one HTTP client. The balance/provider layer lives behind api.pixfaro.com — this code is intentionally small enough to read before you hand it a key.
