## 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 (1)

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

### `sim_registration_rules`

- 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
Whether a prepaid SIM or eSIM must be registered to an identity in a country, who must register, with which document, and what happens otherwise. Includes the official source and check date. General information, not legal advice.
```

## Only reads (3)

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

### `get_package`

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

Description, as the server wrote it:

```untrusted-server-text
Details of one package by the id that list_packages returned, e.g. "tr-10gb-30d" or "tr-daily-3gb".
```

### `list_packages`

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

Description, as the server wrote it:

```untrusted-server-text
List the eSIM packages for one country: data volume, validity, speed, price in EUR (VAT included), daily plans, the monthly pool and the mobile networks used. Includes the page url to choose a plan.
```

### `search_countries`

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

Description, as the server wrote it:

```untrusted-server-text
Find countries by name or ISO code and see whether LibrePass offers an eSIM there. Returns at most 10 matches with their ids.
```

## Claude Code permissions

      "mcp__librepass__get_package"
