Use when the user asks to create or generate an image, visual, logo, thumbnail, infographic, product shot, hero image, OG image, blog/Substack header, sticker, portrait, or any text-to-image or image-generation task; edit a photo; compose multiple images; refine an image iteratively; set aspect ratio/resolution; or visualize real-time data (weather, stocks, news) with Gemini's Nano Banana Pro. Not for text generation, design feedback (design:design-critique), or template designs (Canva MCP).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

How to install
mdr add mycelium-hq/ai-brain-starter/nano-banana@sha256:2df3aa86e332b86bThe line at the top of this page pins the label git:20260707.f0ac903, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
