## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-18.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 74/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1031 tokens (~257/item across 4 items; 3 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).
  - Supports UI / widget rendering.

## Install

### How do I install the Laplace’s Mini World MCP server?

Laplace’s Mini World is a hosted endpoint at https://world.lapla.si/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-18 (score 72, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-10-17 (score 71, 0)

- [functional improvement] Stability: unverified → 0.03

### 2026-10-16 (score 71)

## MCP tools (3)

### `search_models` (~262 tokens)

Find a science model

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.

Input parameters:

- `lang` (string): Language of the results: zh (Chinese) or en (English). Default: the query’s language.
- `limit` (integer): How many plates to return at most.
- `query` (string, required): The user’s question in their own words, in any language (e.g. “why is the sky blue”, “光刻机是怎么工作的”), or a topic (“black hole”, “黑洞”).

### `show_model` (~213 tokens)

Show a live 3D 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.

Input parameters:

- `chapter` (string): The chapter id to open at, from search_models or list_chapters (e.g. "tilt"). Default: the cover.
- `lab` (boolean): Open the lab panel.
- `lang` (string): zh (Chinese) or en (English).
- `params` (object): Lab settings by id, from search_models or list_chapters: a number for a slider, an option id for a choice, true/false for a toggle.
- `slug` (string, required): The plate id from search_models (e.g. "seasons").

### `list_chapters` (~96 tokens)

List a model’s 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.

Input parameters:

- `lang` (string): zh (Chinese) or en (English).
- `slug` (string, required): The plate id from search_models (e.g. "tides").

Laplace’s Mini World scores 72 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Laplace’s Mini World MCP server expose?

Laplace’s Mini World exposes 3 tools: search_models, show_model, list_chapters. Their descriptions and schemas cost roughly 571 tokens of context every time the server is loaded.

### Does the Laplace’s Mini World MCP server require authentication?

No. We connected to Laplace’s Mini World without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Laplace’s Mini World MCP server still maintained?
