Overview

AI-generated overview

Answers keyboard size and desk-fit questions: compares layouts and 30 measured keyboards, checks desk space, and searches HLPlanet reviews.

What you can do
  • List standard keyboard sizes with key counts, typical dimensions and missing keys
  • Compare 2–6 sizes or real keyboards by width, depth, keys lost and mouse room
  • Look up measured case dimensions of reviewed keyboards by name or size
  • Check whether a keyboard and mousepad fit on a desk, including a 360° turn
  • Find which sizes have a given key or key group, and which need an Fn layer
  • Search HLPlanet reviews, comparisons and guides, and list its online testers
When to use it
Useful when someone is choosing a keyboard size or model and wants concrete numbers: how much smaller a 75% is than a TKL, which keys disappear, whether a keyboard plus mousepad fits a given desk, or which reviewed keyboards match a size.
Requirements
Runs locally over stdio via npx, or as a local HTTP endpoint with the --http flag; needs Node.js 18 or newer. No API key or account. Only the review search tool uses the internet.
Before you install
All tools are described as read-only. The review search sends queries to the HLPlanet.com search API, so those queries leave the machine. Standard-size figures are estimates based on key spacing plus an assumed case border, and layouts follow the most common arrangement, so brand-specific differences are possible.

Installation

In SourceWeft

  1. Open HLPlanet Keyboard Sizes in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

HLPlanet MCP: keyboard sizes, dimensions and desk fit

An MCP server that lets AI assistants answer keyboard size questions with real data:

  • Compare full-size, 98%, TKL, 75%, 65% and 60% layouts: size difference, missing keys, extra mouse room
  • Look up the measured dimensions of 30 keyboards reviewed on HLPlanet
  • Check whether a keyboard and mousepad fit on your desk, including a full 360° turn at your sensitivity
  • Find out which sizes have a key (Delete, F5, Insert, arrows, numpad...)
  • Search HLPlanet reviews of Hall effect, TMR and rapid trigger keyboards and gaming controllers

The data matches the interactive keyboard size comparison on HLPlanet, and every answer links to it so you can see the layouts to scale.

"Will a TKL and my 45 cm mousepad fit on a 120 cm desk?" "How much smaller is a 75% than a TKL, and what keys do I lose?" "How wide is the MCHOSE Jet 75 compared to the Wooting 80HE?" "Which keyboard sizes still have a Delete key?"

Install

No API key or account needed. Requires Node.js 18 or newer.

Claude Desktop: download hlplanet-mcp.mcpb from the latest release and double-click it. Or add this to claude_desktop_config.json:

json
{  "mcpServers": {    "hlplanet": {      "command": "npx",      "args": ["-y", "hlplanet-mcp"]    }  }}

Claude Code

bash
claude mcp add hlplanet -- npx -y hlplanet-mcp

Cursor: add the same mcpServers block as above to ~/.cursor/mcp.json.

VS Code

bash
code --add-mcp "{\"name\":\"hlplanet\",\"command\":\"npx\",\"args\":[\"-y\",\"hlplanet-mcp\"]}"

Streamable HTTP: npx -y hlplanet-mcp --http serves the MCP endpoint at http://localhost:3000/mcp (set PORT to change it).

Tools

All tools are read-only. search_hlplanet is the only one that uses the internet (the HLPlanet.com search API); everything else runs offline.

About the data

  • Standard sizes use the 19.05 mm key spacing plus an estimated 10 mm case border. Layouts follow the most common arrangement of each size; some brands move a few keys.
  • Real keyboards use the case dimensions measured in each HLPlanet review.
  • The desk check places the keyboard with its B key in front of the screen centre and leaves 3 cm between keyboard and mousepad, the same as the desk planner on the website.
