**4 tools: 1 do something that can't be undone and 3 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |

| Changes things | write | 0 | ask |
| Only reads | read | 3 | allow |

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "purchase_info" says "purchase": a word that usually means money moves, which cannot be taken back.
```


## Can't be undone (1)

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

### `purchase_info`

- The name "purchase_info" says "purchase": a word that usually means money moves, which cannot be taken back.
- 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
Explain how to pay for a QuietProof audit with x402 on Base, including network, USDC asset, payee, challenge flow, and request format. Free.
```

## Only reads (3)

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

### `describe_rulepack`

- The name "describe_rulepack" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the full input schema, example input, output schema, result example, endpoint, price, and purchase flow for one SKU. Free.
```

### `health`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return service health, service version, and the number of available audit rulepacks. Free.
```

### `list_rulepacks`

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

Description, as the server wrote it:

```untrusted-server-text
List all QuietProof audit rulepacks/SKUs with price, endpoint path, description, and input summary. Free.
```

## Claude Code permissions
