## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__morse__quote_send` |

## Findings

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

```untrusted-server-text
The server marks "quote_send" 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 "quote_send" says "send": a word for sending, and what is sent cannot be taken back.
```


## Can't be undone (1)

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

### `quote_send`

- The name "quote_send" says "send": a word for sending, and what is sent cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The name "quote_send" says "send": it sends or publishes something to other people.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns an indicative quote for sending money with Morse from a person living in from_country to someone else's bank account in to_country: the amount sent, the fee, the mid-market exchange rate and what the recipient gets. The result includes the total cost of the transfer and the typical delivery time. Use it to answer how much a transfer costs or how much will arrive. Use list_send_destinations first to check the destination is offered. Present the figures as indicative and tell the user to check the final rate and fees in the Morse app, using get_started_url.
```

## Only reads (2)

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

### `get_exchange_rate`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the current mid-market exchange rate between two currencies as the number of units of to_currency per one unit of from_currency, with the time it was read. Use it to answer how much one currency is worth in another. It does not say whether Morse can send money in either currency; use list_send_destinations for that. The rate is indicative; show get_started_url as the way to continue in the Morse app, where the rate applied to a transfer is shown before the user confirms.
```

### `list_send_destinations`

- The name "list_send_destinations" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the countries, currencies and payment rails a person living in from_country can send money to with Morse when paying someone else's bank account, with the typical delivery time for each. Use it to answer whether Morse can send from one country to another. An empty destinations list means sending to other people's bank accounts is not offered from that country. When the result includes get_started_url, show it to the user as the way to continue in the Morse app.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__morse__get_exchange_rate",
      "mcp__morse__list_send_destinations"
    ],
    "ask": [
      "mcp__morse__quote_send"
    ],
    "deny": []
  }
}
```

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