Cronus UI is a remote MCP server that gives an AI agent 8 tools, among them get_component, get_design_context, get_install_command. It answers at https://aicronus.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 23 October 2026, succeeded.
Search, install, compose, add-page, and theme Cronus UI from the live registry.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_component | Fetch the full detail for a single Cronus UI component or block by name: its source file(s) (path + content), its npm `dependencies`, its `registryDependencies` (other registry items it needs), and the `npx cronus-ui add <name>` install com Inputs: name |
get_design_context | Return the Cronus UI visual taste file (DESIGN.md) for a theme × look. Use this before generating UI so the agent follows Aurora/Neutral dual identity, one primary CTA, hairline elevation, and look rules. compact fits a system prompt; exten Inputs: theme, look, format |
get_install_command | Build the `npx cronus-ui add ...` command for one or more components/blocks. The CLI resolves and installs each item's registry dependencies automatically. This only returns the command string — to actually install, use `install_component`. Inputs: names |
list_blocks | List the installable Cronus UI blocks (registry items of type 'registry:block') — larger, composed sections such as hero, pricing, login, and dashboard. Returns each block's name, title, dependencies, and its `npx cronus-ui add <name>` inst |
list_catalog | Return compact Hydra-ready cards for every component, block, variant, and template: name, short description, design style, palette, motion, intents, and the install command. No source files — cheap on tokens. Filter with `kind`. Use `match_ Inputs: kind |
list_components | List the installable Cronus UI components (registry items of type 'registry:ui'). Returns each component's name, a readable title, its npm and registry dependencies, and the `npx cronus-ui add <name>` command to install it. |
match_catalog | Two-query catalog match for low-context agents. Pass a free-text `query` (e.g. 'login page with smooth animation') and/or structured filters (`intent`, `motion`, `style`, `palette`). Returns `pick` (the recommended combination), `intent` hi Inputs: query, intent, style, palette, motion, kind |
search_registry | Fuzzy-search Cronus UI components and blocks by name (case-insensitive substring match). Use this to find the right item before fetching its source with `get_component`. Inputs: query |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://aicronus.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
