## MCP tools (6)

### `search_docs` (~116 tokens)

Search Box Kite

Find the prop, component, nesting key or rule for what you are trying to build. Ranked across all four, so a goal ("fade in on mount", "sticky header", "right-to-left") finds the answer without knowing its name. Start here.

Input parameters:

- `kind` (string): Narrow to one corpus. Leave out to search all four.
- `limit` (integer): How many hits (default 12).
- `query` (string, required): What the UI should do, a CSS property, or a name you half-remember.

### `get_props` (~238 tokens)

Box style props

The full record for named style props: the CSS they write, every value they accept, and a measured example — plus, for a numeric prop, the scale measured at 1/2/4/8, because the dividers differ per prop (235 props in all). Nesting keys are answered here too: hover, focus, focusVisible, hasFocus, active, valid, hasValid, invalid, hasInvalid, optional, hasChecked, hasRequired, hasDisabled, visited, target, open, placeholderShown, autofill, inRange, outOfRange, inert, rtl, ltr, indeterminate, checked, required, disabled, selected, before, after, placeholder, selection, marker, firstLine, firstLetter, backdrop, fileButton, sm, md, lg, xl, xxl, pointerCoarse, pointerFine, motionReduce, forcedColors, contrastMore, cq, dataAttr, ariaAttr, has, not, nth, group, peer, theme, startingStyle.

Input parameters:

- `names` (array, required): Prop names, e.g. ["fontSize", "borderRadius", "bgColor"].

### `get_component` (~112 tokens)

Box Kite component

One component's whole contract: its props and their defaults, its sub-parts, its keyboard map and the ARIA it writes. Ask before composing a Dialog, Menu, Tabs, Combobox, DataGrid or any other behaviour component — the accessible mechanics are already in it.

Input parameters:

- `include` (array): Only these sections. Leave out for all of them.
- `name` (string, required): Component name, e.g. "Tabs", "DataGrid", "Popover". A part name works too ("Tabs.Tab").

### `check_styles` (~121 tokens)

Check props against the engine

Run a prop bag through the real styling engine and get back the CSS each prop writes — or why it wrote none. This is the only way to be sure: an unknown prop and an unaccepted value both produce no rule and no class name, with no warning anywhere. Use it on any prop bag you were not certain about, especially numbers and colour tokens.

Input parameters:

- `props` (object, required): The props as JSON, exactly as written: {"p": 4, "bgColor": "blue-550", "hover": {"opacity": 1}}.

### `get_rules` (~79 tokens)

Box Kite rules

The 55 rules this library is written by — where the element comes from, where HTML attributes go, how a layer is anchored, how a theme scopes. With no arguments it lists all 55 headings; pass numbers for the ones you need in full.

Input parameters:

- `numbers` (array): Rule numbers to read in full. Leave out for the index.

### `get_blocks` (~73 tokens)

Installable blocks

Whole sections rather than atoms — a data-grid page, a settings form, a dashboard shell — installed by the shadcn CLI, which also installs the package. Reach for one before composing a large surface by hand.

Input parameters:

- `name` (string): A block name for its files and dependencies. Leave out to list them.

## Common questions

### What is the Box Kite MCP server?

Box Kite is an MCP server listed in the public MCP registry as io.github.box-kite/mcp. Box Kite's React styling engine as tools: props, components, and whether a value writes CSS. This page covers its npm package (@box-kite/mcp).

### Is the Box Kite MCP server safe to use?

Box Kite scores 90 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Box Kite MCP server expose?

Box Kite exposes 6 tools: search_docs, get_props, get_component, check_styles, get_rules, get_blocks. Their descriptions and schemas cost roughly 739 tokens of context every time the server is loaded.

### Is the Box Kite MCP server still maintained?

Box Kite is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Box Kite MCP server under?

Box Kite declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Box Kite MCP server?

VerifyMCP ran 16 checks on Box Kite, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
