## MCP tools (7)

### `list_keyboard_sizes` (~84 tokens)

List keyboard sizes

List the standard keyboard sizes (full-size 100%, 98%/1800, TKL 80%, 75%, 65%, 60%) with key count, typical dimensions, the keys each one drops compared to full-size, and who it suits. Use it for general questions like "what keyboard sizes are there" or "which size should I get".

### `compare_keyboards` (~369 tokens)

Compare keyboards

Compare two to six keyboard sizes or real keyboards side by side: width, depth, key count, the keys each one is missing compared to the first, and how much desk / mouse room you gain. Accepts sizes ("TKL", "75%", "60") and keyboards reviewed on HLPlanet ("Wooting 60HE v2", "MCHOSE Jet 75"). Known keyboards: Redragon K761 Pro, Epomaker Galaxy100, NuPhy Air100 V3, ATK x QK Hex80, Wooting 80HE, GamaKay TK75 TMR, Yunzii RT75, NuPhy Kick75, Epomaker HE75 Mag, IQUNIX EZ75, Varmilo Minilo 75, Epomaker HE75 V2 TMR, DrunkDeer G75, MCHOSE Jet 75, XVX L75 Air, NuPhy Air75 V3, Keychron K3 HE, NuPhy Air75 HE, Keydous AJ68-CP, Epomaker HE65 V2 TMR, MCHOSE Ace 68 GT, Melgeek Made68 Ultra V2, Weikav NUT65, Varmilo Muse65 HE, Wooting 60HE v2, XVX Trooper63 HE, Epomaker Hack 59, Wooting 60HE+, IQUNIX EV63, DrunkDeer G60.

Input parameters:

- `iso` (boolean): Use the ISO layout (UK/EU, tall Enter, extra key by left Shift). Default ANSI.
- `keyboards` (array, required): Sizes or keyboard names. The first one is the reference, e.g. ["TKL", "75%", "Wooting 80HE"]

### `get_keyboard_dimensions` (~119 tokens)

Get keyboard dimensions

Measured case dimensions (width x depth) of keyboards reviewed on HLPlanet, with a link to each review. Search by name ("NuPhy Air75"), list every keyboard of one size ("75%"), or leave both empty to list all of them.

Input parameters:

- `query` (string): Keyboard name or part of it, e.g. "Wooting" or "Jet 75"
- `size` (string): Only keyboards of this size: 100%, 98%, TKL, 75%, 65% or 60%

### `check_desk_fit` (~270 tokens)

Check desk and mousepad fit

Check whether a keyboard and mousepad fit side by side on a desk. The keyboard is placed with its B key in front of the screen centre (move it with keyboard_offset_cm). Returns the mouse room left, whether the pad fits or how far it hangs off, how far the mouse sits from the screen centre, and whether a full 360-degree turn at the given sensitivity (cm/360) fits on the pad. Compare several keyboards at once to see which one leaves the most room.

Input parameters:

- `cm_per_360` (number): Mouse sensitivity as cm of movement for a full 360 turn
- `desk_width_cm` (number, required): Desk width in cm
- `keyboard_offset_cm` (number): Move the keyboard from centred; negative moves it left
- `keyboards` (array, required): Sizes or keyboard names, e.g. ["TKL", "75%"]
- `left_handed` (boolean): Mouse on the left of the keyboard
- `mousepad` (string): small 25x21, medium 36x30, large 45x40, xl 49x42, deskmat 90x40 (under keyboard and mouse), or custom
- `mousepad_width_cm` (number): Mousepad width in cm, when mousepad is "custom"

### `which_sizes_have_key` (~113 tokens)

Which keyboard sizes have a key

Check which keyboard sizes have a key or key group, e.g. "Delete", "F5", "Insert", "Print Screen", "backtick", "arrow keys", "numpad", "function keys". Sizes without it usually reach it through an Fn layer.

Input parameters:

- `iso` (boolean): Use the ISO layout (UK/EU)
- `key` (string, required): A key name or group: "Delete", "F12", "Home", "arrow keys", "numpad"...

### `search_hlplanet` (~118 tokens)

Search HLPlanet reviews

Search HLPlanet.com, a review site for Hall effect, TMR and rapid trigger keyboards, gaming controllers and gaming gear. Returns matching reviews, comparisons and guides with links. Use it to find a review of a specific keyboard or controller, or articles on a topic like "TMR 75%" or "stick drift".

Input parameters:

- `limit` (integer): Number of results (1-10)
- `query` (string, required): What to search for, e.g. "Wooting 80HE" or "low profile hall effect"

### `list_testing_tools` (~74 tokens)

List free testing tools

List free browser tools from HLPlanet for testing keyboards and controllers: keyboard tester (every key, rollover, chatter, rapid trigger, SOCD / Snap Tap), gamepad and stick drift tester, controller reaction time test and keyboard size comparison. These need a person at the device, so share the links rather than running them.
