Laplace’s Mini World tools (3)

write = sends, deletes, buys or posts
  • list_chaptersFree

    Lists one plate’s chapters (ids and titles) and the lab settings it accepts (ids, ranges, options), for show_model. Use it when the user wants another part of a plate than the one search_models gave, or wants to set the lab.

  • search_modelsFree

    Use this when the user asks how something works or why something happens in physics, engineering, AI, biology and medicine, earth and space science or mathematics, or asks to see or try a mechanism: e.g. “why do we have seasons”, “how does a jet engine work”, “潮汐是怎么形成的”, “Transformer 的注意力是什么”. Searches the interactive 3D models (“plates”) on world.lapla.si: first an index of the questions each plate answers (Chinese and English), then titles and topics. Returns the best plates, each with its slug, the chapter that answers the question and sometimes lab settings, to pass to show_model. Returns no results when no plate covers the question. Not for news, prices, homework calculations, or medical, legal or financial advice.

  • show_modelFree

    Shows one interactive 3D model from world.lapla.si in the conversation, opening at the chapter that answers the user’s question; the user can turn it, step through its chapters and try its lab. Use it after search_models with the slug and chapter (and params) it returned, or when the user names a plate. Also returns a short text summary and the plate’s link, for clients that show no UI.

Laplace’s Mini World — MCP server

English · 中文

Live, interactive 3D science models from world.lapla.si, right inside ChatGPT, Claude, Cursor and any other MCP client.

Ask “why do we have seasons?”, “show me how a jet engine works” or “用迷你世界给我看看黑洞”: the assistant finds the right model and puts it in the conversation. Turn it, step through its chapters, and change things in its laboratory, such as the tilt of the Earth’s axis.

https://world.lapla.si/mcp

No account, no API key, no sign-in. Read-only. Streamable HTTP.

What the models are

world.lapla.si (拉普拉斯的迷你世界, Laplace’s Mini World) is a set of over 100 “plates”: each one a working 3D model in the browser, a short illustrated essay with its sources, and a laboratory to try things in. Every plate says what it simplifies. Chinese and English.

Some of them: the seasons, tides, a solar eclipse, a black hole, the Orionids, hurricanes, tsunamis, rainbows, a turbofan, a tokamak, EUV lithography, the Antikythera mechanism, Enigma, a perceptron, attention in a transformer, CRISPR, Fourier series, the Lorenz attractor, the Hopf fibration. The full list is in /models.json and /llms.txt.

Tools

All three tools are read-only (readOnlyHint: true, destructiveHint: false, openWorldHint: false, idempotentHint: true).

The server speaks MCP 2026-07-28 (stateless, server/discover) and the earlier handshake versions (2025-11-25, 2025-06-18, 2025-03-26). The interactive UI is a ui:// resource with mimeType text/html;profile=mcp-app.
