**1 tool: 1 change things.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 1 | ask |
| Only reads | read | 0 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input.

| 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. | `mcp__citation-check__check_citation` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_citation`

- Nothing in its name or description says what it does, so it is counted as a write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Check whether a URL supports a claim. Costs 0.08 credit. Key: https://firm.bestsmartgoods.com/signup
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__citation-check__check_citation"
    ],
    "deny": []
  }
}
```

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

- `mcp__citation-check__check_citation`: outbound

- **warn** Credentials asked for, no protected resource metadata ([remote-auth-metadata-missing](https://anlyon.dev/methodology#remote-auth-metadata-missing))

```untrusted-server-text
The endpoint asks for credentials (HTTP 401) but publishes no RFC 9728 protected resource metadata: no resource_metadata in WWW-Authenticate and no document at /.well-known/oauth-protected-resource.
