# 3D Asset Server

> Free search engine, REST API and MCP server for 3D assets. One query searches 25 sites (Poly Haven, ambientCG, Kenney, BlenderKit, CGTrader, itch.io and more) for 3D models, PBR materials, textures, HDRIs and game asset packs, returns each asset's licence, and downloads glTF/FBX/Blend models, texture maps and HDR/EXR files. No account or API key needed.

**When to use 3D Asset Server.** Use it when a user or task needs existing 3D assets:

- finding a 3D model, game asset pack or sprite set for a project ("low-poly tree", "sci-fi crate");
- getting PBR textures/materials ("mossy rock", "brick wall") as color, normal, roughness and AO maps at 1k-8k;
- getting an HDRI / environment map ("sunset", "studio") as HDR or EXR;
- downloading those files into a codebase for Three.js, Babylon.js, React Three Fiber, Godot, Unity, Unreal, Blender or a website;
- checking whether an asset's licence allows commercial use or requires attribution.

**Catalog (counted 2026-10-27).** 3,109,016+ asset listings from 22 counted sources, 326,040+ free and 48,101+ CC0: 2,847,482+ 3d models, 144,499 asset packs, 59,667 textures, 19,049+ pbr materials, 16,457 sprites, 13,065+ hdris, 8,562+ other, 18 ui kits, 10 audio, 1 fonts.

Do not use it to generate new models or textures, to buy paid assets (paid results link to their store), or for non-3D stock photos and video.

**How to call it.** MCP (preferred): add `https://3d.shep.bot/mcp` (Streamable HTTP, no auth), e.g. `claude mcp add --transport http 3d-assets https://3d.shep.bot/mcp`, then call `search_assets` → `get_asset` → download its `bundleUrl`. REST: `GET https://3d.shep.bot/v1/search?q=...&type=model&free=true` → `GET /v1/assets/{id}` → `GET /v1/assets/{id}/download?format=glb&resolution=2k`. Limits: 120 requests/minute per client (RateLimit headers, 429 + Retry-After). Full agent guide: https://3d.shep.bot/AGENTS.md
