## 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

No check matched anything in these tool definitions.


## Changes things (4)

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

### `bazi_pillars`

- 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
Four Pillars (八字) for a birth moment: converts the clock time with the zone rules for that date (daylight saving included) and the longitude to true solar time; the year follows Li Chun and the day changes at 23:00 true solar time. Returns the pillars, Day Master, five-element counts and the time conversion details.
```

### `best_times`

- 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
Cast a Qi Men chart for every double-hour of the next few days and rank them for a goal, using the person's Day Master from the birth date. Returns the top windows with date, hour branch, true-solar-time range, score and the lucky direction at that time.
```

### `qimen_chart`

- 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
Cast an hour-based Qi Men Dun Jia (奇门遁甲) chart for a moment and place: four pillars, ju, Chief Star and Door, and for each of the nine palaces the deity, star, door, heaven/earth/hidden stems, void, horse star, punishment and door pressure, plus detected patterns, palace scores for the chosen focus and the lucky directions.
```

### `solar_terms`

- 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
The 24 solar terms (节气) of a calendar year, 1900-2100, with UTC and Beijing-time instants from the same table the charts use (within about a minute of the Hong Kong Observatory).
```
