MCP Game Asset Generator — Demo video

Youtube video: https://youtu.be/KSVpJFqF5hg Hi, I created mcp-game-asset-gen - an MCP server that allows Gemini CLI to easily generate 3d models and game textures. It supports a number of providers including Gemini for image generation and fal.ai for 3d model generation. You can install it into gemini CLI using "gemini extensions install https://github.com/Flux159/mcp-game-asset-gen" and API keys in your environment. The open source 3js scene is at https://github.com/Flux159/three-generator The mcp server has a few novel features like using a status file for tracking status of 3d model generation because that can take a few minutes (while mcp has a default timeout of 60s) and supporting alpha transparency for texture generation (needed for grass, leaves textures, etc. & not supported by default by many image gen models). The goal of the mcp server is to help developers fall into "pit of success" for 3d asset creation.
