## 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__serverscan__check_payment_page` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__serverscan__check_payment_page` |

## Findings

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

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

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

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

```untrusted-server-text
The server marks "start_order" 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 "start_order" says "start": a word for a change.
```


## Changes things (3)

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

### `check_payment_page`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Runs ServerScan's free one-off check of a payment or checkout page: TLS, security headers, the HTTP to HTTPS redirect, which scripts load and from where, and whether third-party scripts carry an integrity hash (PCI DSS 6.4.3 and 11.6.1). Returns six yes/no/not-yet-known answers and what to fix first. It fetches the page once. Any one site can be checked only a few times a day, and a repeat within 15 minutes returns the stored answer.
```

### `do_i_need_an_asv_scan`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Says whether a merchant's PCI DSS self-assessment questionnaire (SAQ) requires quarterly external scans by an Approved Scanning Vendor, under PCI DSS v4.0.1, and what to scan. Pass the SAQ type, or "unsure" to get every SAQ with who it is for.
```

### `start_order`

- The name "start_order" says "start": a word for a change.
- 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
Returns a link to ServerScan's signup page with the plan picked and the domain filled in, for the person to open, check and pay. Creates nothing and charges nothing. For a penetration test it returns the quote request page.
```

## Only reads (1)

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

### `get_pricing`

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

Description, as the server wrote it:

```untrusted-server-text
Current prices for ServerScan PCI ASV scanning (per domain or IP address), payment page monitoring and penetration testing, read live from the store, with what each plan includes and the refund terms.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__serverscan__get_pricing"
    ],
    "ask": [
      "mcp__serverscan__do_i_need_an_asv_scan",
      "mcp__serverscan__check_payment_page",
      "mcp__serverscan__start_order"
    ],
    "deny": []
  }
}
```

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