What this MCP does

Searches the Cronus UI registry and provides component or block source, dependencies, installation commands, design guidance, and catalog matching.

Capabilities

Tools

8 tools
get_component
Get a Cronus UI component or block
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.
Read only
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['name'], 'properties': {'name': {'type': 'string', 'description': "The exact registry item name, e.g. 'button', 'data-table', or 'pricing'."}}}
get_design_context
Get Cronus UI DESIGN.md taste
Return the Cronus UI visual taste file (DESIGN.md) for a theme × look. Use this before generating UI so the agent follows Aurora/Neutral dual identity, one primary CTA, hairline elevation, and look rules. compact fits a system prompt; extended is the repo file. Does not modify the project.
Read only
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'look': {'enum': ['default', 'brutalist', 'glass'], 'type': 'string', 'description': 'Material: default, brutalist, or glass. Orthogonal to theme.'}, 'theme': {'enum': ['aurora', 'neutral', 'midnight', 'sunset', 'emerald'], 'type': 'string', 'description': 'Palette: aurora (generated product), neutral (docs chrome), midnight, sunset, emerald.'}, 'format': {'enum': ['compact', 'extended'], 'type': 'string', 'description': 'compact (~prompt) or extended (full DESIGN.md). Default extended.'}}}
get_install_command
Build a Cronus UI 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`.
Read only
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['names'], 'properties': {'names': {'type': 'array', 'items': {'type': 'string'}, 'minItems': 1, 'description': "One or more registry item names to install, e.g. ['button', 'card', 'dialog']."}}}
list_blocks
List Cronus UI blocks
List the installable Cronus UI blocks (registry items of type 'registry:block') — larger, composed sections such as hero, pricing, login, and dashboard. Returns each block's name, title, dependencies, and its `npx cronus-ui add <name>` install command.
Read only
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
list_catalog
List the tagged Cronus UI 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_catalog` to pick the best item for a prompt (login + smooth animation, etc.).
Read only
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'kind': {'enum': ['component', 'block', 'variant', 'template'], 'type': 'string', 'description': 'Restrict to component, block, variant, or template cards.'}}}
list_components
List Cronus UI components
List the installable Cronus UI components (registry items of type 'registry:ui'). Returns each component's name, a readable title, its npm and registry dependencies, and the `npx cronus-ui add <name>` command to install it.
Read only
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
match_catalog
Match Cronus UI catalog tags
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.
Read only
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'kind': {'enum': ['component', 'block', 'variant', 'template'], 'type': 'string', 'description': 'Restrict to component, block, variant, or template.'}, 'limit': {'type': 'integer', 'maximum': 24, 'minimum': 1, 'description': 'Max hits per list. Default 8.'}, 'query': {'type': 'string', 'description': "Natural-language request, e.g. 'login page with smooth animation'. Intent and motion are inferred from the text when those fields are omitted."}, 'style': {'type': 'string', 'description': 'Design style: default, editorial, operational, glass, brutalist.'}, 'intent': {'type': 'string', 'description': 'Use-case intent: login, signup, pricing, dashboard, chart, form, …'}, 'motion': {'type': 'string', 'description': 'Motion: none, snappy, smooth, cinematic.'}, 'palette': {'type': 'string', 'description': 'Palette: semantic (follows theme), aurora, neutral, midnight, sunset, emerald.'}}}
search_registry
Search the Cronus UI registry
Fuzzy-search Cronus UI components and blocks by name (case-insensitive substring match). Use this to find the right item before fetching its source with `get_component`.
Read only
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['query'], 'properties': {'query': {'type': 'string', 'description': "Search text matched against component and block names, e.g. 'button' or 'card'."}}}
