MCP server

The API is also an MCP server, so AI assistants can answer keyboard size questions with these numbers instead of guessing.

Endpoint

https://api.hlplanet.com/mcp

Streamable HTTP transport, stateless, no sign-in or API key. Every tool is read-only and returns a Markdown answer plus the same data as JSON (structuredContent, described by the tool's outputSchema).

Clients that discover servers before connecting can read the server card or the domain's AI catalog.

Tools

Prefer a local server? The same tools run offline with npx -y hlplanet-mcp (npm).

Privacy

The server keeps no logs of tool arguments and sets no cookies. search_hlplanet sends the search text to the HLPlanet site search; every other tool answers from data built into the server.
