AI Sprite & Game Asset Tool with its own local MCP server and Agent skills
View on GitHub ↗A local-first character animation workbench that turns a text prompt (and optional reference image) into reusable animation clips and versioned engine-ready bundles. Azure GPT Image, Gemini, or an independently operated loopback ComfyUI server can do the generative work; a deterministic Python pipeline handles repair, palettes, sprite-sheet packing, frame ZIPs, bundle checksums, and Godot resources. Side-scroller walks also provide Gemini with deterministic eight-phase pose guides, so frames change limb geometry instead of merely restyling the same stance.
