## Description

A browser-based 3D studio in which an agent can inspect scene geometry and materials and edit them through declared tools, while the user watches the viewport update. Part of OpenAI's set of WebMCP reference applications demonstrating agent-native interfaces beyond text.

The pattern it demonstrates — an agent with structured read and write access to live application state — is the one that generalises. Its declared capabilities are browser control and outbound network access, and the work stays inside the page. The security question it raises for real applications built this way is provenance: when a model and a human both mutate the same document through the same tools, the application needs to record which changes came from which, or review becomes impossible.

## Why it scored 10

The score starts at the catalog's neutral base of 50 and moves only through the signals below. The formula is published at https://catalog.anomity.ai/about — there is no model and no hidden heuristic.

| Signal | Contribution | Severity | Evidence |
| --- | --- | --- | --- |
| Published by the vendor | -40 | trust offset |  |

Clamped result: **10/100**, band **low**.

## Capabilities

| Capability | Name | Security implication |
| --- | --- | --- |
| `browser:control` | Browser control | Drives a browser session. Combined with credential access can impersonate the user on web services. |
| `network:outbound` | Outbound network | Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access. |
