## 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 (5)

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

### `birth_time_check`

- 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
How sensitive the chart is to the recorded birth time, in plain language: minutes earlier or later until the rising sign changes, the same for the Moon nakshatra quarter (pada) and the D9 and D10 rising signs, and how many days the life chapter dates move per minute of birth time. It does not correct the birth time. Birth details are used only to calculate this answer and are not stored.
```

### `chart_overview`

- 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
A short plain-language summary of the sidereal birth chart (True Chitrapaksha ayanamsa): the rising sign, the Moon sign and nakshatra and the Sun sign, each with a one-line meaning, and the running Vimshottari life chapter and sub-chapter (month and year). Up to 3 answers per chart every 6 hours, shared with life_area and current_chapter. Birth details are used only to calculate this answer; a one-way code is kept for 6 hours to apply fair-use limits.
```

### `current_chapter`

- 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 Vimshottari life chapter (mahadasha) and sub-chapter (antardasha) running today, with month and year, in plain language: what their planets stand for, the houses they sit in and guide, the life areas they touch, and when the next sub-chapter starts. Finer periods are not included. Up to 3 answers per chart every 6 hours, shared with chart_overview and life_area. Birth details are used only to calculate this answer; a one-way code is kept for 6 hours to apply fair-use limits.
```

### `life_area`

- 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
Plain-language findings from the birth chart for one area of life: how strong the area's main house is, the planet that guides it and where it sits, the other houses and planets for the area, support from planets (strong, mixed or needs effort), and whether the running life chapter touches the area. Areas: career, relationships, wealth, home_property, children, education, foreign_settlement, spiritual_growth. Health is not covered. Up to 3 answers per chart every 6 hours, shared with chart_overview and current_chapter. Birth details are used only to calculate this answer; a one-way code is kept for 6 hours to apply fair-use limits.
```

### `panchang`

- 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
Weekday, tithi, paksha, nakshatra, yoga and karana for a date and place, calculated at 12:00 local time unless a time is given. Sunrise, sunset and Rahu kalam are not included. Birth details are used only to calculate this answer and are not stored.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `find_birthplace`

- The name "find_birthplace" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up a town in the Astrodai atlas (towns above about 15,000 people; places at or beyond 66 degrees latitude are not supported). Returns up to 5 candidates, each with a place_token for the other tools. Add the region or country after a comma to narrow the search. If nothing matches, try the nearest larger town.
```
