## 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__triphook__list_cities` `mcp__triphook__search_destinations` |
| 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.

### `events_and_company`

- 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
Use for any question about what is happening in a city on a date (city slug, date YYYY-MM-DD) and whether other travellers are going: each listed event with its ticket link (url), the TripHook What's on page for that day (whats_on), how many open public day outs are going and their links (company). The reply ends with links: show them as one short line, for example "Search on TripHook · What's on". Public fields only, never a person.
```

## Only reads (3)

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

### `list_cities`

- The name "list_cities" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "find" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Use to find which cities have open group trips and day outs, with counts of trips and day outs, each city's slug (for the other tools) and its TripHook city page (url). The reply ends with links: show them as one short line, for example "Search on TripHook". For any where should I go, where is warm or budget question, use search_destinations instead.
```

### `search_destinations`

- The name "search_destinations" says "search": a word for reading.
- 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
Use for any question like "where should I go" with a budget, a temperature, a mood, dates or a month: the same TripHook Discover search a signed out visitor gets, ranked from Vienna or the given departure city. Give dates { depart, ret } or a month (1 to 12); where, from, temp_min, temp_max, budget_eur, mood, travellers and limit (max 20) are optional. Each result carries city, country, why it matched, the weather labelled Forecast or Typical, an estimated price marked "estimate, not a quote", a TripHook link that opens this search for that city (url) and, when the city has open crews, its crew page (crew_url). Show the weather as "forecast" or "typical"; do not repeat the weather source name in your answer. Typical means the usual temperature for that time of year, not a forecast. The reply ends with links: show them as one short line, for example "Search on TripHook · Find a crew". No personal data.
```

### `search_public_hooks`

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

Description, as the server wrote it:

```untrusted-server-text
Use for any question about open trips or day outs to join: by city slug, month (YYYY-MM), kind (trip or dayout), budget tier or mood. Each hook carries its public TripHook page (url) and, for a day out, the What's on page (event_page). The reply ends with links: show them as one short line, for example "Search on TripHook · Find a crew". Public fields only, never a person. For any where should I go, where is warm or budget question, use search_destinations instead.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__triphook__search_public_hooks",
      "mcp__triphook__list_cities",
      "mcp__triphook__search_destinations"
    ],
    "ask": [
      "mcp__triphook__events_and_company"
    ],
    "deny": []
  }
}
```

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

- `mcp__triphook__list_cities`: untrusted-input
- `mcp__triphook__search_destinations`: untrusted-input
