## 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__paid-call-checkout-conformance-probe__get_verdict` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__paid-call-checkout-conformance-probe__get_verdict` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `pricing`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Packet pricing sheet (free).
```

### `run_probe`

- The name "run_probe" says "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Fresh settled probes collect payment on the HTTP x402 surface (POST /probe); refused over MCP.
```

## Only reads (1)

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

### `get_verdict`

- The name "get_verdict" says "get": a word for reading.
- Tag untrusted-input: The description's first sentence says "http": it reads web pages, which anyone can write. The input takes a URL (input.endpoint), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.endpoint): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Verdict lookup is a paid HTTP x402 call (GET /verdict, $0.01); MCP returns the payment instructions.
```

## Claude Code permissions

      "mcp__paid-call-checkout-conformance-probe__run_probe"
    ],
    "deny": []
  }
}
