## Changes things (3)

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

### `natal_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
Calculates a natal (birth) chart with the Swiss Ephemeris: the exact sign, degree and house of the Sun, Moon, planets, North Node and Chiron; the Ascendant, MC, DSC and IC; the 12 house cusps; and the major aspects between the planets with their orbs. Adds short notes and links from the AstralRead knowledge base for the Sun, Moon and Ascendant signs. Use it when someone asks for their birth chart or about their placements. Needs the birth date, the place (or coordinates) and ideally the birth time. Birth data is used only for this calculation and is not stored or logged.
```

### `vedic_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
Calculates a Vedic (Jyotish) birth chart with the Swiss Ephemeris: sidereal zodiac with the Lahiri ayanamsa, whole-sign houses from the Lagna (Ascendant), the rashi, degree and house of the nine grahas (Sun to Saturn, Rahu as the mean node and Ketu opposite), and the nakshatra, pada and nakshatra lord of the Lagna and every graha, with the traditional symbol and deity of the Moon's nakshatra. Use it for questions like 'what is my nakshatra', 'my Vedic chart' or 'my rashi / Moon sign in Jyotish'. Pure calculation: no doshas, yogas or predictions. Birth data is used only for this calculation and is not stored or logged.
```

### `vimshottari_dasha`

- 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
Calculates the Vimshottari dasha periods of a birth chart (Swiss Ephemeris, Lahiri ayanamsa): the Moon's nakshatra at birth, the balance of the first Mahadasha, the full Mahadasha sequence from birth with start and end dates, and the Mahadasha, Antardasha and Pratyantardasha running on a given date plus the next two Antardashas. Use it for questions like 'which Mahadasha am I in' or 'when does my Saturn dasha start'. Dates use a 365.25-day year. The result lists the classical themes of the running periods, not predictions. Birth data is used only for this calculation and is not stored or logged.
```

## Only reads (3)

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

### `kb_lookup`

- The name "kb_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Finds pages of the AstralRead astrology knowledge base for a chart factor and returns each page's title, a one- or two-sentence summary and its link. Understands planets in signs and houses ('Moon in Taurus', 'Mars in 10th house'), Ascendant/MC signs, aspects ('Venus square Saturn'), houses ('7th house'), patterns ('grand trine', 'T-square', 'yod'), North Node and Chiron placements, and transits ('Saturn transit Aries', 'transiting Saturn square Venus', 'Saturn return'). English or Russian.
```

### `sky_today`

- The description's first verb is "return": a word for reading.
- Tag private-data: The description's first sentence says "return" and "calendar": it reads calendars.

Description, as the server wrote it:

```untrusted-server-text
Returns the sky of one calendar day from the Swiss Ephemeris: the Moon's sign, phase and illumination, lunations and eclipses, planet sign changes, retrograde/direct stations, exact aspects between planets, which planets are retrograde, and every planet's position, plus a link to the AstralRead 'Sky of the day' page. No birth data needed. English uses UTC times, Russian uses Moscow time.
```

### `transits_today`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists the tight transits of a given day to a natal chart: aspects of the transiting Moon, Sun, Mercury, Venus, Mars, Jupiter and Saturn to the natal planets, Ascendant and MC within 2° (3° for Jupiter and Saturn), plus each planet's current sign and natal house and the Moon phase. Use it for questions like 'what are my transits today' or 'what is happening in my chart this week'. The date defaults to today in the person's time zone. Computed with the Swiss Ephemeris; no forecast text is generated. Birth data is used only for this calculation and is not stored or logged.
```
