## 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__trip720__plan_trip` `mcp__trip720__swap_trip_item` `mcp__trip720__trip_alternatives` |
| 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.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `swap_trip_item`

- The description's first verb is "replace": a word for a change.
- The server marks it destructive (destructiveHint: true).
- 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
Replaces one line of an option with one of the numbered choices from trip_alternatives, and re-prices the whole trip as the website does. Returns the updated option and its Safe Trip Total before and after. Side effect: the trip saved on Trip720 changes; the previous choice can be chosen again the same way. Nothing is booked or paid.
```

## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `plan_trip`

- The input carries an amount (input.budget.amount) and a currency, so it moves money.
- 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
For a request to plan a trip with a budget. Plans a whole trip, home to home, against the traveller's total budget: flights, stays, transfers, activities, visas and daily costs. Returns up to six options, each with a Safe Trip Total (the whole trip with a contingency), the route, and every price labelled live (checked with the provider), estimate (Trip720's own, protection margin included) or official (a government fee), with a link to the option on trip720.travel where it is booked. Side effect: the trip is saved on Trip720 (kept 30 days) so it can be opened and booked; nothing is booked or paid. Limits: at most 6 travellers, 60 nights and 5 named places; flight fares are estimates in this quick build. A trip still being built comes back with status 'building' and its trip id.
```

## Changes things (4)

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

### `best_time_to_visit`

- 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
When to go to a country, month by month: the best months overall, each covered place's most pleasant months, and the busy holiday weeks to plan around. From climate data (NASA POWER) and Trip720's research. Read only.
```

### `check_entry_requirements`

- 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 travellers need a visa or an electronic authorisation for a holiday, for each passport and each destination country: the rule's name, the minimum processing days and its source (official government pages where available). Read only.
```

### `destination_facts`

- 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
Trip720's checked facts for one destination, for travellers from Australia or the UK: what a day costs a person for food and getting around (street food, balanced, mostly restaurants), local transport and taxi prices, tourist tax, the most pleasant months, the visa for that home country, the sights not to miss with tips, and the total of a sample priced trip. Each figure comes from Trip720's research with its sources, in AUD or GBP. Read only; no booking or search is made. Places not covered say so and list the covered places in that country.
```

### `trip_alternatives`

- 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
For one line of an option in a trip already planned on Trip720 (a stay, a flight, a transfer, an activity), the other choices the providers offer, numbered, each with its price and what it does to the whole trip's Safe Trip Total and budget. Line ids and option ids come from plan_trip or get_trip. Read only; searches the providers again.
```

## Only reads (2)

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

### `get_day_plan`

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

Description, as the server wrote it:

```untrusted-server-text
The day-by-day plan of one option of a trip already planned on Trip720 (the recommended option unless optionId is given): times, places and prices for each day. Read only; times marked typical are not from a timetable.
```

### `get_trip`

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

Description, as the server wrote it:

```untrusted-server-text
Reads a trip already planned on Trip720, by its trip id: its status and, when ready, its options with every labelled price and booking link. Read only; trips are kept 30 days.
```
