## 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 2026-10-23.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 84/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 3046 tokens (~84/item across 36 items; 21 tools + 15 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 21 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 23 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (21)

### `check_contrast` (~200 tokens)

Contrast

Check colour contrast. Give fg and bg, or pairs (a list of {fg, bg, label, sizePx, bold}), or a palette. Returns the WCAG 2.2 ratio with AA and AAA results for the text size, APCA Lc with what it is enough for, the nearest passing colour, and for palettes the colour pairs that become indistinguishable under protanopia, deuteranopia or tritanopia. Accepts hex, rgb(), hsl() and CSS names.

Input parameters:

- `bg` (string): Background colour
- `bold` (boolean): True if the text is bold, which changes the large-text threshold
- `fg` (string): Foreground colour
- `pairs` (array): Several pairs at once
- `palette` (array): Colours to test against white, black and each other under colour blindness
- `sizePx` (number): Text size in CSS px, default 16

### `audit_page_accessibility` (~155 tokens)

Page accessibility

Audit one page's static HTML for accessibility problems and name the WCAG 2.2 criterion for each: missing lang or title, images without alt, unlabelled form fields, vague or empty links and buttons, heading jumps, no main landmark, zoom-blocking viewport, autoplay with sound, tabindex above zero, duplicate ids, click handlers on non-interactive elements, tiny inline targets. It reads markup only and cannot test contrast, focus order or script-built widgets.

Input parameters:

- `compareUrl` (string): A second URL (for example the redesign): returns what was fixed, what is new and what remains
- `html` (string): Or paste HTML instead
- `url` (string): Public page to fetch

### `heuristic_worksheet` (~148 tokens)

Heuristic review

Build a Nielsen ten-heuristics review worksheet for a screen or flow. Give text (the copy of the flow), html or a url. Returns, for each heuristic, keyword and markup signals found or missing, review prompts, and blanks for findings and 0 to 4 severity. The signals point at where to look; a human evaluation is still required.

Input parameters:

- `html` (string): Page HTML, if you have it instead of a URL
- `task` (string): The task the reviewer is evaluating, e.g. 'change a billing address'
- `text` (string): Screen or flow copy
- `url` (string): Public page to read instead of pasted text

### `detect_design_slop` (~117 tokens)

AI design slop

Look for the default AI-generated design look in a live page's markup and CSS: purple-to-blue gradients, gradient text, a default font stack, pill buttons with arrows, uppercase eyebrow labels, emoji headings, glassmorphism, glow blobs, equal card grids, stock marketing phrases and placeholder copy. Returns weighted signals and a 0 to 100 score. Signals, not proof.

Input parameters:

- `compareUrl` (string): A second URL: returns what became less or more generic
- `url` (string, required): Public page to read

### `review_ui_copy` (~127 tokens)

UI copy

Review interface copy, one string per line, optionally prefixed with a type (button:, error:, empty:, tooltip:, placeholder:, heading:, toast:, label:).

Input parameters:

- `items` (array): Or a list of strings or {text, type}
- `text` (string): One string per line, e.g. 'button: Submit' or 'error: Invalid input'

### `lint_design_feedback` (~76 tokens)

Input parameters:

- `text` (string, required): One note per line, or paragraphs

### `plan_critique` (~129 tokens)

Critique plan

Input parameters:

- `mode` (string): Default interview
- `text` (string, required): One question per line

### `usability_stats` (~326 tokens)

### `build_heuristic_report` (~117 tokens)

- `title` (string): Report title

### `getting_started` (~89 tokens)

Check target sizes and spacing against WCAG 2.2 SC 2.5.8 (24 by 24 CSS px, or a smaller target with enough spacing), the 44px guidance for iOS and the web, and 48dp for Android. Pass targets as a list of {name, width, height, gap, inline} or text lines like 'Save button 40x32 gap=8'. Returns pass or fail per guideline with advice.

Input parameters:

- `targets` (array): Targets to check
- `text` (string): Or lines like 'Close icon 32x32 gap=4'

### `lint_token_names` (~72 tokens)

Token names

Lint design token names from a list, CSS variables or a JSON token file: mixed separators, colours named by hue where roles belong, values or locations in names, version words, duplicate values, abbreviation drift (bg and background) and irregular scales.

Input parameters:

- `text` (string, required): Token names or file contents

### `lint_design_md` (~78 tokens)

DESIGN.md check

Score a DESIGN.md (the brand and design context file models read before building): missing sections, no hex values, text and background pairs that fail contrast, too many typefaces, adjectives a model reads as the generic look, no never-list, no sizes, too long or too thin.

Input parameters:

- `text` (string, required): The DESIGN.md contents

Input parameters:

- `content` (string, required): The text to save
- `name` (string, required): e.g. design-md, brand-voice

## Common questions

### What is the Designers MCP server?

Designers is an MCP server listed in the public MCP registry as com.allthepossibles/designers. Checks, prompts and skills for designers working with AI: contrast, a11y, heuristics, critique. This page covers its hosted endpoint (https://designers.allthepossibles.com/mcp).

### Is the Designers MCP server safe to use?

Designers scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Designers MCP server expose?

Designers exposes 21 tools: check_contrast, audit_page_accessibility, heuristic_worksheet, detect_design_slop, review_ui_copy, and 16 more. Their descriptions and schemas cost roughly 2,510 tokens of context every time the server is loaded.

### Does the Designers MCP server require authentication?

No. We connected to Designers without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Designers MCP server still maintained?

Designers is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
