## Exfil surface

1 private-data -> untrusted-input -> outbound path in this server alone. Denying 1 outbound tool breaks every one: `mcp__api-operation__lookup_operation`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__api-operation__lookup_operation` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__api-operation__lookup_operation` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__api-operation__lookup_operation` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__api-operation__lookup_operation` | `mcp__api-operation__lookup_operation` | `mcp__api-operation__lookup_operation` |

## Findings

No check matched anything in these tool definitions.


## Only reads (1)

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

### `lookup_operation`

- The name "lookup_operation" says "lookup": a word for reading.
- Tag private-data: The description's first sentence says "read" and "document": it reads documents.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): 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
Read one operation from a public OpenAPI or Swagger JSON document, or from a simple YAML document. Returns the method, path, operation id, summary, and required parameter and body fields. Send the document URL and a short intent, for example create a pet. The best text match is returned. A private address, a login wall, or a document with no matching operation is not charged. The first 5 successful reads each UTC day from one network address are free and need no key. After the 5, send X-API-Key. A key call costs 0.04 credit when an operation is returned. Do not send a URL on a private network. Key: https://firm.bestsmartgoods.com/signup
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `api-operation`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__api-operation__lookup_operation"
    ],
    "deny": []
  }
}
```

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

- `mcp__api-operation__lookup_operation`: private-data, untrusted-input, outbound
