A production-ready MCP server for AI-powered image generation using Nano Banana 2.1 (default), Gemini 3 Pro Image, and Gemini 2.5 Flash Image with intelligent model selection
Until 2026-09-26 this record combined several servers published from one repository. The others now have records of their own: iflow-mcp_nanobanana-mcp-server. Checks from before that date include them.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"andrew-nanobanana-mcp-server","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.
