## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `match_catalog`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (7)

Looks things up and changes nothing. Claude Code: allow.

### `get_component`

- The name "get_component" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_context`

- The name "get_design_context" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_command`

- The name "get_install_command" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_blocks`

- The name "list_blocks" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_catalog`

- The name "list_catalog" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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_components`

- The name "list_components" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `search_registry`

- The name "search_registry" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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`.
```

## Claude Code permissions
