Nvidia Usdcode MCP Server

🚀 nvidia-usdcode-mcp-server

A minimal MCP server that exposes a single tool backed by NVIDIA USDCode via the NVIDIA Integrate API. Ideal for Isaac Sim scripting tips, USD, Python snippets, and API usage.

🚀 Quick Start

Requirements

• Node.js 18+
• An NVIDIA API key in NVIDIA_API_KEY, obtainable from here

You can place it in a local .env file (loaded automatically) or export it in your shell.

Installation

Dependencies are already vendored in this workspace. If you need to reinstall:

• npm ci or npm install

Build

• npm run build

Outputs to dist/.

Run (standalone)

• npm start (after building)

The server communicates using MCP over stdio and is designed to be launched by an MCP-capable client.
