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 serverserver.json: the official MCP Registry entryllms-install.md: setup notes for agents that install from a READMEThe 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.
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.
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.

Or point any agent at https://3dassets.dev/skill.md directly. The skill uses plain HTTP, so it works without MCP.
Base https://3dassets.dev/api/v1, OpenAPI at https://3dassets.dev/api/v1/openapi.json, guide at https://3dassets.dev/docs/api. Every asset also has a Markdown view at https://3dassets.dev/assets/{slug}.md.
Every asset on the site is CC0 1.0. The files in this repository are CC0 1.0 too.
