## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__rates__get_hours_and_limits` |
| 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. | `mcp__rates__convert_currency` |

## Findings

- **warn** Annotations that disagree with the tool in `convert_currency` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "convert_currency" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "convert_currency" says "convert": a word for a change.
```


## Can't be undone (1)

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

### `convert_currency`

- The name "convert_currency" says "convert": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
How much an amount comes to at FXHUB's live rate, for example "How much is 1,000 USD in GEL at FXHUB?" or "How many euros do I get for 5,000 GEL?". Returns the result, the rate used and which side applies, with notes on hours and limits. Indicative only: nothing is exchanged.
```

## Only reads (2)

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

### `get_exchange_rates`

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

Description, as the server wrote it:

```untrusted-server-text
Live FXHUB exchange rates (Tbilisi, Georgia): online exchange by bank transfer and the cash exchange point, each with buy and sell, plus the National Bank of Georgia official rate. Use for questions like "What is FXHUB's dollar rate?" or "FXHUB euro rate today", or to compare FXHUB with the NBG rate or another provider. Leave pair empty for every pair.
```

### `get_hours_and_limits`

- The name "get_hours_and_limits" says "get": a word for reading.
- Tag private-data: The description's first sentence says "contact": it reads contacts.

Description, as the server wrote it:

```untrusted-server-text
When FXHUB is open, where the cash exchange point is, evening and weekend limits, limits without registration, how online exchange works, regulation and contact details.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__rates__get_exchange_rates",
      "mcp__rates__get_hours_and_limits"
    ],
    "ask": [
      "mcp__rates__convert_currency"
    ],
    "deny": []
  }
}
```

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

- `mcp__rates__convert_currency`: outbound
- `mcp__rates__get_hours_and_limits`: private-data
