## 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__travel-safety__travel_advice_countries` `mcp__travel-safety__travel_advice_country` `mcp__travel-safety__travel_advice_entry_requirements` `mcp__travel-safety__travel_advice_health` `mcp__travel-safety__travel_advice_recent_updates` `mcp__travel-safety__travel_advice_safety` `mcp__travel-safety__travel_advice_warnings_insurance` |
| 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 `travel_advice_recent_updates` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "travel_advice_recent_updates" 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 "travel_advice_recent_updates" says "update": a word for a change.
```


## Changes things (7)

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

### `travel_advice_countries`

- 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
Which countries and territories does the UK Foreign Office publish travel advice for, and what is the slug for each? Lists every FCDO travel advice destination with its GOV.UK slug and the alternative names GOV.UK maps to it (for example Dubai to United Arab Emirates, Tenerife to Spain), so other travel advice tools can be called with the right slug. Optional search narrows the list. Live from the GOV.UK Content API; it returns names only, not the advice itself. (cost: 1 credit)
```

### `travel_advice_country`

- 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
Is it safe to travel to a country, according to the UK Foreign Office? Returns the FCDO headline for one country: whether it advises against all or all-but-essential travel (to the whole country or to parts), the latest change and when it was made, recent change history and the sections available. Live from the GOV.UK Content API. Advice is written for British nationals; it does not give other governments' advice and does not replace reading the full warnings before booking. (cost: 1 credit)
```

### `travel_advice_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.
- 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
Do I need a visa, and how long must my passport be valid? Returns the FCDO 'Entry requirements' section for one country as headed plain-text subsections: passport validity, visas and length of stay, dual nationals, vaccine certificates and customs rules. Live from the GOV.UK Content API. Written for travellers on a full British citizen passport; other nationalities must check with the destination's embassy, and the destination's own authorities set and enforce the rules. (cost: 1 credit)
```

### `travel_advice_health`

- 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
What jabs do I need, can I take my medication, and what is the ambulance number? Returns the FCDO 'Health' section for one country as headed plain-text subsections: emergency medical number, vaccine and health-risk pointers, medicines rules and local healthcare. Live from the GOV.UK Content API. The FCDO points to TravelHealthPro and NHS fitfortravel for vaccine detail, which this tool does not fetch; it is not medical advice. (cost: 1 credit)
```

### `travel_advice_recent_updates`

- The name "travel_advice_recent_updates" says "update": 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
Which countries' UK travel advice changed most recently, and what changed? Lists FCDO travel advice pages newest first, with the time of each update and the FCDO's own one-line summary of the change. Live from the GOV.UK Content API, for travel managers, agents and journalists. Shows only the latest change per country; use travel_advice_country for a country's earlier changes. (cost: 1 credit)
```

### `travel_advice_safety`

- 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
Is there a terror threat, how bad is crime, and which local laws catch visitors out? Returns the FCDO 'Safety and security' section for one country as headed plain-text subsections: terrorism, protests, crime and scams, laws and cultural differences, outdoor activities and transport risks. Live from the GOV.UK Content API. Region-by-region detail for some countries sits in a separate 'Regional risks' section; this tool does not return its text, but gives its link in also_see when it exists. (cost: 1 credit)
```

### `travel_advice_warnings_insurance`

- 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
Will my travel insurance still be valid? Returns the FCDO 'Warnings and insurance' section for one country: the official warning levels, the areas they cover and the insurance guidance, as headed plain-text subsections, plus the machine-readable alert status. Live from the GOV.UK Content API. The FCDO's warning maps are images and are not returned; whether a particular policy pays out depends on its own terms. (cost: 1 credit)
```
