Here’s what’s unique: no existing project simultaneously combines an MCP hub with n8n as the backbone orchestration engine (not just a target), creative bridges (Blender), a pedagogical transparency layer that makes the invisible visible, and an LLM-agnostic architecture with a ready-to-use “recipes” system.

There are existing MCP gateways (Bifrost, ContextForge, MetaMCP), but none of them simultaneously combine :

• n8n as the orchestration backbone (not just a target)

• Blender 3D via native WebSocket

• A PTL (Pedagogical Transparency Layer) : every tool call logged in readable English, phase by phase

• 4 LLM adapters (Claude, OpenAI, Gemini, Ollama) in a single repo

• A recipe system that can be activated via CLI

• An architecture explicitly designed for teaching

One MCP server. Any LLM. Every tool.
