3DAssets.dev tools (20, 6 write)

write = sends, deletes, buys or posts
  • create_accountwrite actionFree

    Create a contributor account for the user. Needs only a username and email. There is no password anywhere in this product, so never ask the user for one. A 6-digit code is emailed to them; ask the user to read it to you, then call verify_account to receive their API key. Only do this with the user’s explicit consent.

  • finalize_uploadwrite actionFree

    After PUTting the file to the URL from get_upload_url, describe the asset and submit it for processing and review.

  • get_assetFree

    Full details for one asset by slug: CDN URL, licence + attribution text, stats, bounding box, animations, and ready-to-paste loader snippets.

  • get_asset_usageFree

    Code or steps to load an asset in three.js, React Three Fiber, <model-viewer>, Blender, Godot or Unity.

  • get_demoFree

    Get one demo: the pack, the spawn point, the walkable bounds, the points of interest, and every placement (public asset slug, position in metres, yaw in degrees) with the CDN URL and bounds of each model placed. Load the models with a plain GLTFLoader and apply the transforms to reproduce the scene.

  • get_packFree

    Get a free pack manifest with direct CDN URLs, licences, geometry budgets, loader snippets and its assembled starter scene. Download models individually or use the starter scene.

  • get_upload_urlwrite actionFree

    For clients that can upload bytes: returns a presigned PUT URL for a .glb (and optionally a PNG preview). Then call finalize_upload with the returned keys.

  • list_ai_modelsFree

    Search model suggestions from OpenRouter, refreshed hourly. Custom model/tool names are accepted; the list is not exhaustive. Unavailable suggestions never block uploads.

  • list_categoriesFree

    List categories available on 3dassets.dev (slugs are what other tools accept).

  • list_demosFree

    List the walkable demo scenes staff have built from single packs. Each is a small environment a person can walk through on the site and an agent can load as a layout. Use get_demo for the placements.

  • list_licensesFree

    Returns the sole accepted submission dedication: CC0 1.0 Universal. No licence selection is needed.

  • list_tagsFree

    List tags available on 3dassets.dev (slugs are what other tools accept).

  • my_assetsFree

    List the user’s submissions with status (processing, pending review, published, rejected + reason, failed + reason). `pendingEdit` means the user has metadata changes waiting for review; the published version is unchanged until they are approved.

  • my_packsFree

    List the user’s pack proposals with status (submitted, approved + pack URL, rejected + reason) and the status of each member model.

  • search_assetsFree

    Search the free GLB catalogue on 3dassets.dev (three.js, Blender, Godot, Unity) by text, category (what it is), theme (what world) and style (what look). Returns direct CDN URLs (CORS *, immutable) that load with a plain GLTFLoader. Published models use CC0 1.0 Universal: free personal and commercial use without attribution. Licence metadata is retained in each result.

  • search_packsFree

    Find cohesive free GLB game kits by text, theme or style. Returns file counts, total bytes and starter scene URLs. Use get_pack for every individual model and loader snippet.

  • submit_asset_from_urlwrite actionFree

    Submit a .glb hosted at a public https URL on the user’s behalf (requires their API key). We download it, validate and re-encode it, then a human reviews it before publishing. CC0 is automatic, but the user must accept its irrevocable dedication before submission. Max 25 MB, 1M triangles, embedded textures only.

  • submit_packwrite actionFree

    Group 2–50 of the user’s own uploads (any that are processing, pending or published) into a pack proposal. Upload the models first with finalize_upload or submit_asset_from_url, then pass their slugs here. Each model is still reviewed on its own; a person approves the pack as a whole, which publishes any members still pending and creates the pack page. Nothing goes live until then. The user is emailed the outcome.

  • update_assetwrite actionFree

    Edit the metadata of one of the user’s own assets. The uploaded GLB can never be changed. Editing an asset that is already published does not change it: the proposal goes to the review queue and the live version keeps serving until a person approves it.

  • verify_accountFree

    Exchange the emailed 6-digit code for the account’s API key. Show the key to the user and tell them to configure it as the Bearer token for this MCP server.

What the publisher says

From the 3DAssets.dev repository's README, as published. We do not edit it. Read it on GitHub

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 THREEDASSETSAPIKEY 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

Skill

npx skills add 3dassets-dev/3dassets

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

REST API
