## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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 `lookup_reason_code` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "lookup_reason_code" 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 "lookup_reason_code" says "lookup": a word for reading.
```

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

```untrusted-server-text
The server marks "get_help_with_a_dispute" 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 "get_help_with_a_dispute" says "get": a word for reading.
```


## Changes things (2)

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

### `get_help_with_a_dispute`

- The name "get_help_with_a_dispute" says "get": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
For a merchant with a chargeback open now. Explains how to get a custom response to it, with the first one free. Pass the reason code if you know it.
```

### `lookup_reason_code`

- The name "lookup_reason_code" says "lookup": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text

```

## Only reads (2)

### `list_reason_codes`

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

Description, as the server wrote it:

```untrusted-server-text

```
