3DAssets.dev MCP server

• 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.
