@tools/nge-mcp-server

MCP server for AI-driven Babylon.js Node Geometry authoring.

Provides

• create and manage in-memory Node Geometry graphs
• add blocks, connect ports, and set block properties
• inspect graph structure and validate geometry graphs
• export and import NGE JSON
• import from and save to Babylon.js snippets

Typical Workflow

create_geometry -> add_block -> connect_blocks -> set_block_properties -> validate_geometry -> export_geometry_json

The exported JSON can be used directly in Scene MCP to create a mesh at runtime.

Binary

babylonjs-node-geometry

Build And Run

npm run build -w @tools/nge-mcp-server
npm run start -w @tools/nge-mcp-server

Integration

Exported NGE JSON can be consumed by the Scene MCP server through add_node_geometry_mesh, either inline or via ngeJsonFile.
