## What it does

The server connects coding agents to the `3dassets.dev` repository of web-optimised GLB assets. Everything in the catalog is CC0 1.0. Through tools like `search_assets` and `get_pack`, the assistant inspects tags, downloads models, and retrieves implementation demos.

Two connection methods are available. You can point your client directly to the hosted endpoint at `https://3dassets.dev/mcp` or run a local stdio bridge via `3dassets-mcp`. No local files are retained.

Searching and downloading assets requires no credentials. If you plan to submit models through an agent, set the `THREEDASSETS_API_KEY` environment variable.

## Requirements
- Needs: Node.js (commands run via npx)
- Remote server: `https://3dassets.dev/mcp`
- Environment variables: `THREEDASSETS_API_KEY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- search web-optimised GLB models by tag or category
- fetch CC0 asset packs for three.js or Godot
- inspect 3D model usage examples directly from chat
- upload new 3D assets to the catalog on your behalf

## Example prompts
- Find a low-poly tree model in GLB format for my three.js scene
- Search 3dassets for sci-fi space station asset packs
- Get the download URL and code demo for the retro car asset
