## Changes things (3)

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

### `birth_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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Draw an accurate birth (natal) chart: Sun, Moon and rising sign, every planet with sign, degree and house, the angles and the tightest aspects. Works without a birth time (then no rising sign or houses). Returns a link to the person's sky in 3D on Pluto Garden and guide pages for each placement. Pass the place as the person said it; the server looks it up. Convert the time to 24-hour local time at the birth place.
```

### `famous_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
Birth chart of a celebrity or famous moment from Pluto Garden's sourced collection (e.g. Billie Eilish, Chappell Roan, Lana Del Rey, Bitcoin, the Moon landing). It only holds birth times the person gave themselves, with the source, so a missing name means no self-reported time is known. Returns the big three, placements, source and page link.
```

### `sky_now`

- 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
Today's sky (or any date from 1901 to 2100): the Moon's phase, sign and how much is lit, the next full moon (with its traditional name) and new moon, which planets are retrograde and until when (answers "is Mercury retrograde?"), and the sign of every planet.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `pluto-garden`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__pluto-garden__birth_chart",
      "mcp__pluto-garden__sky_now",
      "mcp__pluto-garden__famous_chart"
    ],
    "deny": []
  }
}
```
