## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__orizn-visa__get_coverage_stats` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__orizn-visa__get_coverage_stats` `mcp__orizn-visa__quick_visa_check` |
| 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.

### `quick_visa_check`

- 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
Does this passport need a visa for this destination? Returns the requirement, the number of visa-free days, and — when that exact pair has been individually re-verified — the date it was. One pair per call, English only. Prefer it when the user wants a plain yes/no; switch to check_visa_requirement as soon as they need documents, fees, processing times, transit rules, or an answer in another language. Keyless and free: it costs nothing against an API key quota. An anonymous caller is capped at 30 DISTINCT pairs per day per network — asking the same pair again is always free, only widening costs. Free API key: https://visa.orizn.app/visa-api?source=mcp — 100 requests/month, no card, and it unlocks documents, fees, processing times, transit rules and 15 languages.
```

## Only reads (1)

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

### `get_coverage_stats`

- The name "get_coverage_stats" says "get": a word for reading.
- Tag private-data: The description's first sentence says "database": it reads databases.
- 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
How big the Orizn visa database is: pairs, passports, destinations, enriched records, translations and languages. Says nothing about any specific country pair — use quick_visa_check or check_visa_requirement for that. Keyless, free, and costs nothing against any quota. Call it when the user asks how complete the data is, or to confirm this server is reachable before a longer session.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `orizn-visa`:

```json
{
  "permissions": {
    "allow": [
      "mcp__orizn-visa__get_coverage_stats"
    ],
    "ask": [
      "mcp__orizn-visa__quick_visa_check"
    ],
    "deny": []
  }
}
```

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

- `mcp__orizn-visa__quick_visa_check`: untrusted-input
- `mcp__orizn-visa__get_coverage_stats`: private-data, untrusted-input
