## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 69 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1124 tokens (~59/item across 19 items; 19 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (19)

### `create_visual_brief` (~124 tokens)

Create Visual Brief

Turn a raw idea into a concise production brief for an immersive VULK project. This does not create a project or call external services.

- `moodboard` (array): Optional visual references, URLs, brand notes, colors, materials, motion references, or inspiration labels.
- `prompt` (string, required): What VULK should build. Include product goal, audience, visual direction, pages, interactions, and delivery constraints.
- `source` (string): Primary input type behind the request.

### `create_project` (~93 tokens)

Create VULK Project

Create a complete VULK project from a prompt and return project, preview, and editor URLs. This may consume account credits.

Input parameters:

- `model` (string): Optional VULK model ID. Omit to let VULK pick the best model allowed by the account.
- `prompt` (string, required): What VULK should build. Include product goal, audience, visual direction, pages, interactions, and delivery constraints.

### `generate_immersive_site` (~171 tokens)

Input parameters:

- `deliveryTarget` (string): Output format VULK should optimize for.
- `model` (string): Optional VULK model ID. Omit to let VULK pick the best model allowed by the account.
- `moodboard` (array): Optional visual references, URLs, brand notes, colors, materials, motion references, or inspiration labels.
