3DAssets.dev does not always answer

Over the last week it answered 98.9% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

This one needs environment variables set before it will start: THREEDASSETS_API_KEY (Optional. The user API key from https://3dassets.dev/account, needed only to submit models on the user behalf.). The author declared them in the registry entry; get the values from the project itself.

Available tools 20

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

asset

get_asset

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

get_asset_usage

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

update_asset

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.

assets

my_assets

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.

search_assets

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.

packs

my_packs

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

search_packs

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

submit_asset_from_url

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_pack

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.

account

create_account

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.

3DAssets.dev — questions

Answers built from our own checks of this server.

What can 3DAssets.dev do?

It exposes 20 tools, read directly from the server on our last check. Among them: create_account, finalize_upload, get_asset, get_asset_usage, get_demo, get_pack and 14 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is 3DAssets.dev mostly used for?

Its tools cluster around asset, assets and packs. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is 3DAssets.dev working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 88 of 91 checks got a reply (96.7%), average response time 445 ms. The bar chart above shows every period we have measured.

How do I connect 3DAssets.dev?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does 3DAssets.dev need an API key?

No. 3DAssets.dev completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 20 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is 3DAssets.dev?

It answers our handshake in 445 ms on average, which is faster than 35% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use 3DAssets.dev?

The npm package 3dassets-mcp was installed 36 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is 3DAssets.dev open source?

Yes — it is published under the CC0-1.0 licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
