## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data 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. | `mcp__orbitstudio__star_map_link` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

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


## Changes things (2)

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

### `star_map_link`

- The name "star_map_link" says "star": a word for a change.
- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Build a link that opens OrbitStudio Sky with the night sky over a place on Earth at a local date and time, as a 3D-printable star map plate. Use it for a birth, wedding or 'night we met' star map. Give a place name, which is looked up on OpenStreetMap, or latitude and longitude, which win when both are given. When a name matches more than one place, the tool lists them instead of choosing: ask the user which one they mean.
```

### `suggest_model`

- 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
Suggest OrbitStudio settings for a 3D-printed puzzle or ornament of a place, from the app's own defaults and the limits of that world's elevation data, plus a link that opens the app at the place with those settings filled in, ready for the user to press Generate. Use it when the user wants to make or print a model of a specific place. Give either a place from search_places or latitude and longitude (a coordinate link cannot carry settings). Shape, size and relief may be chosen; otherwise the app's defaults apply.
```

## Only reads (4)

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

### `get_preview`

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

Description, as the server wrote it:

```untrusted-server-text
Return pictures already published on orbitstudio3d.com for a world or a place: photos of printed models, renders made with the app, and the world's map texture, each captioned with what it shows. Use it when the user wants to see what a model looks like. Nothing is rendered on request.
```

### `get_product_info`

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

Description, as the server wrote it:

```untrusted-server-text
Facts about OrbitStudio: what it makes, its two tools and the worlds offered, which steps are free and which are not, a link to the page that lists the plans, and the support address. Use it when the user asks what OrbitStudio is or which parts of it are free.
```

### `list_worlds`

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

Description, as the server wrote it:

```untrusted-server-text
List the worlds OrbitStudio currently offers, with each world's size, number of known places, default relief, smallest selection and data caveats. Use it when the user asks which planets or moons can be printed.
```

### `search_places`

- The name "search_places" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the named places OrbitStudio can open directly: craters, mountains, valleys, basins and spacecraft landing sites on the Moon and other worlds. Use it when the user names or describes a place to 3D print, or asks what there is on a world. Returns each match's world, coordinates, the size of its box in the app's travel list, a short description and a link that opens the generator at that place.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `orbitstudio`:

```json
{
  "permissions": {
    "allow": [
      "mcp__orbitstudio__search_places",
      "mcp__orbitstudio__get_preview",
      "mcp__orbitstudio__list_worlds",
      "mcp__orbitstudio__get_product_info"
    ],
    "ask": [
      "mcp__orbitstudio__suggest_model",
      "mcp__orbitstudio__star_map_link"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__orbitstudio__star_map_link`: untrusted-input

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://orbitstudio-api-597899603925.europe-west1.run.app/mcp?via=mcp: tools/list returned 6 tools to an anonymous client, including suggest_model (write), star_map_link (write)
