Cronus UI MCP server

• get_componentFree

  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 command. Works for both components and blocks.

• get_design_contextFree

  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; extended is the repo file. Does not modify the project.

• get_install_commandFree

  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`.

• list_blocksFree

  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>` install command.

• list_catalogFree

  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_catalog` to pick the best item for a prompt (login + smooth animation, etc.).

• list_componentsFree

  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_catalogFree

  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` hits, `motion` hits, and ranked `matches`. Cards carry description, design style, palette, motion, and intents — not source. Fetch source with `get_component` only after picking a name.

• search_registryFree

  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`.
