@tools/nrge-mcp-server

MCP server for AI-driven Babylon.js Node Render Graph authoring.

Provides

• create and manage custom render graphs in memory
• add render-graph blocks, connect ports, and set properties
• inspect graph structure and validate output pipelines
• export and import NRGE-compatible JSON
• import from and save to Babylon.js snippets

Typical Workflow

create_render_graph -> add_block -> connect_blocks -> set_block_properties -> validate_graph -> export_graph_json

In practice, a usable render graph usually includes an input block, render or post-process blocks, and an output block.

Binary
