Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 26 October 2026. No other catalogue keeps this.

26 Oct a tool changed the parameters it asks for show_model

Nothing serious here today

Today is the operative word: we check Laplace’s Mini World every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

chapters

list_chapters

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.

models

search_models

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

show_model

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 — questions

Answers built from our own checks of this server.

What can Laplace’s Mini World do?

It exposes 3 tools, read directly from the server on our last check. Among them: list_chapters, search_models, show_model. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Laplace’s Mini World working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 367 ms. The bar chart above shows every period we have measured.

How do I connect Laplace’s Mini World?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Laplace’s Mini World need an API key?

No. Laplace’s Mini World completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Laplace’s Mini World?

It answers our handshake in 367 ms on average, which is faster than 37% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Laplace’s Mini World open source?

We cannot say either way: 1 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
