Over the last week it answered 0.5% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

components
list_components
Every component in the catalogue with name, title, description, category, and aliases. Filter by category: actions, forms, navigation, feedback, surfaces, content, icons, charts, patterns, ios, android, ai, health, civic, science, creative, engineering, geospatial, robotics, electronics, microbiology.
search_components
Find components by name, title, description, alias (AI Elements, shadcn/ui, Radix, and common names such as PromptInput, Chain of thought, Sonner, Drawer, Combobox), or rs-* class. Spacing, punctuation and capitalization do not affect matching. Returns matches ranked by field.
component
get_component
The markdown docs page for a component (install paths, example, props tables, keyboard, accessibility), plus its props as JSON, the CSS-only snippet, the React example, its classes, and aliases. Pass the kebab-case name from list_components or search_components.
guide
get_guide
Read the general guide first for installation and conventions. Select ios or android for browser React components, exact exports and related interface studies; select ai-index for the AI component catalog and optional engine imports, ai for the runnable assistant and integration recipes, ai-parity for AI Elements functional coverage and differences, or agents for machine-readable surfaces and setup.
install
get_install
The three ways to install one component (npm package plus import line, Vlak CLI, shadcn CLI) and the CSS-only markup, with its registry dependencies.
tokens
get_tokens
The design tokens page: every CSS custom property with its light and dark value and StyleX alias, plus the raw token groups (type scale, grid, radius, motion, breakpoints, control sizes).
workflow
get_workflow
Return one bundled workflow manifest and its source files. Authentication, authorization, storage, and deployment remain host responsibilities described by the manifest.
workflows
list_workflows
List bundled workflow kits and recipes. An optional query matches workflow ID, title, description, components, adapters, and states.

Vlak — questions

Answers built from our own checks of this server.

What can Vlak do?
It exposes 8 tools, read directly from the server on our last check. Among them: get_component, get_guide, get_install, get_tokens, get_workflow, list_components and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Vlak working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 61 ms. The bar chart above shows every period we have measured.
The registry lists Vlak as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Vlak?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Vlak need an API key?
No. Vlak completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
Is Vlak open source?
The code is open source: it is published under the MIT licence, written in TypeScript, 33 stars on GitHub and 2 open issues. The licence covers the code in the repository, not the hosted service at vlak.dev, which runs on its operator's own terms.
