## Findings

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

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

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


## Changes things (1)

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

### `create_christmas_star_card`

- The name "create_christmas_star_card" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Creates a festive Christmas card (text plus SVG image) about someone, from their birth date and optional first name: sun sign and life path number, described as character, not prediction. The card text talks about the recipient in the third person (by name, or neutrally without a name). No personal data stored.
```

## Only reads (5)

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

### `compare_charts`

- The name "compare_charts" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compares two birth charts (synastry): the closest aspects between person A's and person B's planets, with orbs and a short, balanced summary. Birth times and places are optional. Instead of person_b you can pass `celebrity` (name or X handle, see list_celebrities) for a playful star match with a score and a share text for X. No predictions, nothing stored.
```

### `get_birth_chart`

- The name "get_birth_chart" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Computes a real birth chart from astronomical positions (tropical zodiac): Sun to Pluto with sign, degree and retrograde flag, major aspects with orbs, and a short character-focused interpretation. Ascendant, Midheaven and Whole Sign houses only when birth time and place are both given. Without a time the Moon is flagged as approximate. No predictions, nothing stored.
```

### `get_sun_sign_reading`

- The name "get_sun_sign_reading" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns a short, free reading based only on a birth date: sun sign (simple date table) and Pythagorean life path number, with a few sentences about character, written in the third person by default. No predictions, no personal data stored.
```

### `get_transits`

- The name "get_transits" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Shows where the planets are now (or on a given UTC date) and which major transits they make to a person's birth chart, with orbs and exact dates, for one day or a 7-day week. Short reflective interpretation, no predictions, nothing stored.
```

### `list_celebrities`

- The name "list_celebrities" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists the famous people you can compare charts with in compare_charts (about 1000 most-followed real people on X, birth dates from Wikidata cross-checked with Grokipedia). Optional search query (name, handle or description such as 'singer'); returns up to 25, most followed first. Most are date-only.
```
