Provides access to NVIDIA USDCode via the NVIDIA Integrate API for Isaac Sim scripting assistance, USD guidance, Python code snippets, and API usage help
nvidia-usdcode-mcp-server
A minimal MCP server that exposes a single tool backed by NVIDIA USDCode via the NVIDIA Integrate API. Great for Isaac Sim scripting tips, USD, Python snippets, and API usage.
Requirements
Node.js 18+
An NVIDIA API key in
NVIDIA_API_KEY, get it from here https://build.nvidia.com/nvidia/usdcode
You can place it in a local .env file (loaded automatically) or export it in your shell.
Quickstart
Dependencies are already vendored in this workspace. If you need to reinstall:
npm ciornpm install
Build
npm run build
Outputs to dist/.
Run (standalone)
npm start(after building)Or directly:
node --enable-source-maps dist/server.js
The server speaks MCP over stdio and is intended to be launched by an MCP-capable client.
Use with Claude Desktop
Add an entry to your ~/.claude/config.json:
{
"mcpServers": {
"usdcode": {
"command": "node",
"args": ["dist/server.js"],
"env": { "NVIDIA_API_KEY": "YOUR_KEY" }, // if you didn't add .env to this project
"disabled": false
}
}
}
Use with OpenAI Codex
Add an entry to your ~/.codex/config.toml:
[mcp_servers.usdcode]
command = "node"
args = ["/absolute/path/to/mcp-usdcode/dist/server.js"]
env = { "NVIDIA_API_KEY" = "value" }
Tool Info
name:
get_usdcode_helpdescription: Ask NVIDIA USDCode for help.
params:
question(string, required): Your prompt or question.temperature(number, optional, default 0.1)top_p(number, optional, default 1)max_tokens(integer, optional, default 1024)expert_type(string, optional, default "auto")
Returns a single text message with the model’s reply.
remote-capable server
The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.
Tools
Enables users to get expert help with Isaac Sim scripting, USD (Universal Scene Description), Python snippets, and API usage through NVIDIA's USDCode AI assistant. Provides specialized guidance for 3D graphics and simulation development workflows.
