About this package

@molecule-ai/mcp-image-gen

Thin MCP server giving an agent image generation through the Molecule platform. It holds no vendor keys and does no billing: it builds the vendor-native request and calls the platform capability socket (/internal/llm/proxy, RFC #3105), which authenticates the workspace, injects the vendor credential server-side, meters usage, and debits org credits. The agent gets back a download URL and decides what to do with it.

Delivered to workspaces by the plugin manifest repo molecule-ai-plugin-image-gen (which references this package via npx).

Tools

  • generate_image(prompt, model?, size?, n?) → download URL(s)
  • edit_image(prompt, image, model?) — image = base64 / data-URL; google/ models only in v1
  • list_image_models()

Models (Tier-A, platform-metered)

  • google/gemini-2.5-flash-image (default) — Gemini 2.5 Flash Image ("Nano Banana")
  • openai/gpt-image-2 — OpenAI GPT Image 2

Configuration (from workspace env — mirrors @molecule-ai/mcp-server)
