Designers
Checks, prompts and skills for designers working with AI: contrast, a11y, heuristics, critique.
What it does
Designers is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

21 tools offered to AI assistants
check_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, aaudit_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-bloheuristic_worksheet· 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 tdetect_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, equreview_ui_copy· Review interface copy, one string per line, optionally prefixed with a type (button:, error:, empty:, tooltip:, placeholder:, heading:, toast:, label:). Checks each string for what its type needs (errors say what to do, empty states give alint_design_feedback· Lint design critique. Sorts each note into observation, opinion, solution-without-problem, vague, or question, explains what is missing, and gives an observation, impact, suggestion skeleton for weak notes. Reports the share of notes readyplan_critique· Plan a design critique for a stage (concept, wireframe, visual, prototype, build, shipped): a framing statement, timed agenda, the questions that fit the stage, roles, and the kinds of feedback to turn away until a later stage.lint_research_questions· Lint user research questions, one per line, for leading wording, double-barrelled questions, hypotheticals, predictions, loaded words, jargon, closed questions in an open interview, why-questions and unlabelled rating scales, with a suggestusability_stats· Usability arithmetic with formulas shown. mode sus: score System Usability Scale responses (rows of ten 1-5 answers) with grade, percentile and 95% interval. mode discovery: participants needed to find a share of problems (Nielsen and Landalint_tracking_plan· Lint a product analytics tracking plan (event names with optional properties, one per line like 'project_created (template, source)') for mixed naming styles, vague events, UI-element names, near-duplicate events, tense and order drift, andaudit_site_accessibility· Pro. Crawl up to 15 same-origin pages from a start URL, audit each one's static HTML for WCAG 2.2 problems, and report issues by how many pages they affect so that shared-template problems come first. Returns a markdown report.check_contrast_tokens· Take a design token file (CSS custom properties like --color-text: #111;, a JSON object of colours, or W3C design tokens) and test every foreground-like token against every background-like token for 4.5:1 text and 3:1 component contrast, wi

build_heuristic_report· Pro. Build a scored, exportable markdown report from heuristic evaluation findings you have written. Each finding has heuristic (1 to 10), severity (0 to 4), location, issue, effect, fix and optional effort (S, M, L) and evaluator. Merges dgetting_started· Explain what this server can do and suggest the three best first tasks for what the person has (a Figma link, a live URL, copy, a research plan, an event list). Use this first when the person is new or unsure what to ask for.whoami· Show the caller's plan (Free or Pro) and how many calls remain today on each tool. Does not use up a daily call.check_touch_targets· 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} olint_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 irlint_design_md· 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-lisdoctor· Diagnose setup problems. Reports what the server sees about this connection (client, whether a Pro key was received and is active, plan), checks a Figma link for the right shape (frame link with node-id, not a prototype or Community page),save_project_context· Pro. Save named project context (brand notes, a DESIGN.md, past decisions, personas) against the Pro key, up to 20 items of 50,000 characters, so later sessions and prompts can reuse it.get_project_context· Pro. List the saved project context, or read one item by name.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
