## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `verdict_meanings`

- 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
The exact semantics of every status and relevance value, including what this checker cannot determine. Read once before trusting a verdict.
```

## Only reads (1)

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

### `check_citation`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch a URL and report whether it exists, and whether the source names the same entity as the claim you attach to it. These are two different questions and conflating them is the failure this exists to catch: a URL can return 200 and describe a different gene entirely. No account needed, nothing is stored about you.
```

## Claude Code permissions

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

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