## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `exam_paper_index`

- 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
Official past-paper archive links per spec (links to the board's own assessment-resources page — papers are board copyright, so no hosted PDFs).
```

### `exam_topic_paper`

- 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
Which exam paper is a topic on? The canonical student revision question ("is electricity paper 2 AQA?" — answer: no, Paper 1). Input a topic plus optional board/subject/level; returns the paper, sibling topics on that paper, spec code, and the official spec URL. Knows quirks like AQA Combined Science Trilogy Physics Paper 2 having no Space physics. Coverage: AQA GCSE Physics (8463); AQA GCSE Biology (8461); AQA GCSE Chemistry (8462); AQA GCSE Combined Science: Trilogy (8464); AQA GCSE Mathematics (8300).
```

## Only reads (1)

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

### `exam_spec_lookup`

- The name "exam_spec_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
UK exam specification metadata: spec codes, paper structure (count, duration, marks, calculator rules, tiers), topic lists per paper, official spec links.
```

## Claude Code permissions
