**14 tools: 12 change things and 2 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `updates` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "updates" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "updates" says "update": a word for a change.
```


## Changes things (12)

Creates or changes something that can be changed back. Claude Code: ask.

### `charts`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Roblox’s own charts (Top Earning, Top Trending, Up-and-Coming and the rest), as RoTerminal keeps them day by day in 60 countries and on every device. With no chart and no game: the list of charts, countries and devices. With a chart: its games now, each with its place yesterday, its move, its best place and its days on the chart (put a country in front for one country’s chart: jp-up-and-coming is Japan’s Up-and-Coming). With a game: every place it holds on the charts now, worldwide and in each country (like JP-Up-and-Coming #4), and each chart’s summary.
```

### `days`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

One game’s players day by day (New York days, newest first): the average, peak and low, visits that day, and what happened (updates, events). Free shows the last 7 days; Pro shows every day since tracking began on Sep 27 2026 (up to 60).

Start here for any question about one game.
