## Exfil surface

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

| 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__settle__settle_report` `mcp__settle__settle_verify` `mcp__settle__settle_watch` `mcp__settle__spend_record` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__settle__receipt_create` `mcp__settle__settle_watch` |

## Findings

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

```untrusted-server-text
The server marks "settle_trial_key" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The description's first verb is "get": a word for reading.
```

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

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

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

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

### `receipt_create`
