About Image Gen

Image Gen is an MCP server published by nuverlabs.com. Generate and edit images from your coding agent with Gemini and OpenAI, using your own API keys.

It runs on your own machine: your AI client starts it from the npm package @nuver-labs/image-gen-mcp at version 0.2.1.

It asks for 2 secrets: GEMINI_API_KEY and OPENAI_API_KEY. Give it a key with the least access that still works.

Version 0.2.1 was published on 13 August 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
