## 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 `create_checkout_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "create_checkout_link" 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 "create_checkout_link" says "create": a word for a change.
```

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

```untrusted-server-text
The server marks "store_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 "store_info" says "store": a word for a change.
```


## Changes things (2)

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

### `create_checkout_link`

- The name "create_checkout_link" says "create": a word for a change.

- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Quote an order (one or more products, 1-10 vials each) and get the checkout link the buyer opens to pay. Nothing is charged or reserved until the buyer pays on that page.
```

### `store_info`

- The name "store_info" says "store": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Where PeptoClinic ships, payment methods, physician review, quality testing and contact.
```

## Only reads (1)

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

### `list_products`

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

Description, as the server wrote it:

```untrusted-server-text
Peptide vials sold in a market, with id, vial size, price per vial and a direct buy link. Products sold in more than one vial size list them all under sizes.
```
