## 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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 66, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (8)

### `generate_color_palette` (~452 tokens)

Generate color palette

Generate a perceptually uniform OKLCH color palette from a brand color: 18-step scales for brand/surface/error/accents, semantic tokens (shadcn/ui compatible), light+dark modes. Returns a shareable standby.design/system URL and a compact summary. Always give that URL to the user — the link is the deliverable; it opens the live system in the browser. Use export_design_system for full CSS/Tailwind output.

Input parameters:

- `accents` (array): Up to 3 additional named accent colors. Replaces the existing accent list when provided; pass [] to remove all accents. Default: Success/Warning/Info, auto-derived.
- `bgColorHex` (string): Surface tint color as hex, or "auto" to derive from the brand color (default).
- `brandHex` (string): Brand color as 6-digit hex, e.g. "#335A7F". The palette midpoint is derived from this.
- `brandInvert` (boolean): For pinned brand: mirror lightness in dark mode (e.g. black buttons in light mode, white in dark).
- `brandPin` (boolean): Pin the primary token to the exact input hex instead of the palette step.
- `chromaScale` (number): Surface saturation 0–1 (0 = grey surfaces, 1 = vibrant). Default 0.25.
- `errorColorHex` (string): Error/destructive color as hex, or "auto" to derive from the brand hue (default).
- `errorInvert` (boolean)
- `errorPin` (boolean)
- `fgContrastMode` (string): Text color strategy on colored backgrounds.
- `mode` (string): "balanced": step 500 is always the perceptual midpoint (even light/dark distribution). "exact": step 500 keeps the input color's lightness.
- `themeName` (string): Name of the design system (appears in exports and page title).
- `url` (string): Existing standby.design URL (or raw hash) to modify. Only this tool's section is changed; color/type/shape/icon/spacing settings from other tools are preserved. Omit to start fresh from defaults.

### `generate_type_scale` (~561 tokens)

Generate a fluid typographic scale (CSS clamp() between 375px and 1920px viewports) with 11 levels (Display, H1–H6, Body L/M/S, Caption), Fontshare fonts, line heights and letter spacing. Returns a shareable standby.design/system URL and a summary table. Always give that URL to the user — the link is the deliverable. Use list_fonts to discover font slugs.

- `scaleMode` (string): "custom": compound ratio scale (default). "traditional": classical Renaissance point sizes per level.
- `traditionalAssignments` (object): For traditional mode: desktop px size per level, e.g. {"display": 48, "h1": 36, ...}.
- `traditionalMobileAssignments` (object): For traditional mode: mobile px size per level.
- `url` (string): Existing standby.design URL (or raw hash) to modify. Only this tool's section is changed; color/type/shape/icon/spacing settings from other tools are preserved. Omit to start fresh from defaults.

### `generate_shape_tokens` (~499 tokens)

### `get_design_system` (~99 tokens)

Inspect design system

Decode a standby.design URL (or raw hash) and return an overview of the full design system: color palette, type scale, spacing & layout, shape tokens, and icons — plus per-tool edit links. Always give the standby.design/system URL to the user — the link is the deliverable.

Input parameters:
