## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Endpoint Security**: 66/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 20 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 2060 tokens (~103/item across 20 items; 20 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 83/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 49% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 20 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 21 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

### `create_account` (~129 tokens)

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.

### `submit_asset_from_url` (~311 tokens)

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.

Input parameters:

- `aiGenerated` (boolean): AI helped create geometry, code or textures; not merely uploading
- `aiModel` (string): Contributor-reported model ID or custom model/tool name; use list_ai_models for suggestions. Omit if unknown.
- `attestation` (boolean, required): Required contributor acceptance (including for agent submissions): I confirm that I created this asset or hold the rights to publish it under CC0 1.0 Universal, and agree to dedicate it to the public…
- `category` (string, required): From list_categories
- `description` (string): Markdown: scale, pivot, what is included
- `license` (string): Fixed CC0 1.0 Universal dedication; no licence selection

Input parameters:

- `contentLength` (integer, required)
- `filename` (string, required)
- `withPreview` (boolean)

### `finalize_upload` (~270 tokens)

Finalize upload

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

Input parameters:

- `aiGenerated` (boolean): AI helped create geometry, code or textures; not merely uploading
- `aiModel` (string): Contributor-reported model ID or custom model/tool name; use list_ai_models for suggestions. Omit if unknown.
- `attestation` (boolean, required): Required contributor acceptance (including for agent submissions): I confirm that I created this asset or hold the rights to publish it under CC0 1.0 Universal, and agree to dedicate it to the public…
- `category` (string, required): From list_categories
- `description` (string): Markdown: scale, pivot, what is included
- `license` (string): Fixed CC0 1.0 Universal dedication; no licence selection
- `previewKey` (string)
- `quarantineKey` (string, required)
- `sourceUrl` (string): Where the original was first published
- `summary` (string, required): Plain 1–2 sentence description
- `tags` (array)
- `title` (string, required)

### `my_assets` (~55 tokens)

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.

### `submit_pack` (~125 tokens)

Propose a 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.

Input parameters:

- `assets` (array, required)
- `description` (string)
- `summary` (string, required)
- `title` (string, required)

### `my_packs` (~37 tokens)

My packs

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

### `update_asset` (~131 tokens)

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.

Input parameters:

- `aiGenerated` (boolean)
- `aiModel` (string): Model ID or custom name; empty string clears attribution
- `category` (string): From list_categories
- `description` (string)
- `slug` (string, required)
- `summary` (string)
- `tags` (array)
- `title` (string)
