ImageGen MCP Server

What it does

ImageGen MCP Server connects your AI agent to multiple leading image generation providers — OpenAI (GPT-Image-1, DALL-E 3), Google (Imagen 4, Gemini 2.5 Flash Image), and Replicate (Flux 1.1 Pro, Qwen Image, SeedDream-4) — through a single unified MCP interface. Ask Claude or any MCP-compatible client to generate images, and it handles model selection, API calls, and saving output to disk.

Tools

• image.generate.openai — Generate images with GPT-Image-1, DALL-E 3, or DALL-E 2; supports transparency, custom sizes, quality levels, and multiple formats.
• image.generate.google — Generate photorealistic images with Google Imagen 4 via a configurable custom endpoint.
• image.generate.gemini — Fast generation via Google's Gemini 2.5 Flash Image Preview model ("Nano Banana").
• image.generate.replicate — Multi-model Replicate interface: Flux 1.1 Pro, Qwen Image, and SeedDream-4; supports seeds for reproducibility.
