What is 3DAssets.dev MCP?

3DAssets.dev searches and download free CC0 GLB models and game asset packs or submit new assets on behalf of a user.

Summary generated from the project's README

About 3DAssets.dev MCP server

3DAssets.dev provides access to a collection of free, web-optimized CC0 GLB models and game asset packs. This server is designed for developers working with tools like three.js, React Three Fiber, Blender, Godot, and Unity. It allows users to find and download assets that are compatible with any glTF-capable software.

Users can connect via a hosted HTTP endpoint or by using the 3dassets-mcp npm package through a stdio bridge. While searching and downloading assets requires no authentication, submitting new models on behalf of a user requires a THREEDASSETS_API_KEY set in the environment. The server includes a wide range of tools such as search_assets, search_packs, get_asset, and submit_asset_from_url to manage the asset lifecycle.

This tool is unique because it offers a direct way for AI agents to interact with a machine-readable catalogue of 3D resources. It supports complex workflows including account creation, asset uploading via get_upload_url, and managing personal collections through my_assets and my_packs.

3DAssets.dev for agents

Free, web-optimised CC0 GLB models and game asset packs for three.js, React Three Fiber, Blender, Godot, Unity and any glTF-capable tool. This repository holds the machine-readable pieces of https://3dassets.dev in one place for directories and agent tooling that index GitHub:

SKILL.md: the agent skill, a copy of https://3dassets.dev/skill.md (kept in sync daily by a workflow)
bin/3dassets-mcp.js: the 3dassets-mcp npm package, a stdio bridge to the hosted server
.mcp.json: MCP client configuration for the hosted server
server.json: the official MCP Registry entry
llms-install.md: setup notes for agents that install from a README

The site, the API and the MCP server itself are hosted at 3dassets.dev, so the only code here is the thin stdio bridge; the catalogue is at https://3dassets.dev/assets.

MCP server

Two ways in. Hosted (Streamable HTTP) needs nothing installed; the npm package runs the same server over stdio for clients that only speak stdio or want a pinned dependency. Both expose the same tools.

# stdio, via npm (bridges to the hosted server; no local state)
npx -y 3dassets-mcp

{
  "mcpServers": {
    "3dassets": { "command": "npx", "args": ["-y", "3dassets-mcp"] }
  }
}

Set THREEDASSETS_API_KEY in the environment to submit models on the user's behalf; leave it unset for read-only use.

Hosted endpoint

Streamable HTTP endpoint: https://3dassets.dev/mcp. Search and download need no auth. Submitting models on a user's behalf takes their API key as a Bearer token; https://3dassets.dev/auth.md explains how an agent obtains one without the user ever handling a password.

# Claude Code
claude mcp add --transport http 3dassets https://3dassets.dev/mcp

# Codex CLI

# VS Code

  }
}

Or point any agent at https://3dassets.dev/skill.md directly. The skill uses plain HTTP, so it works without MCP.
