## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `mot_reliability`

- 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
Real UK MOT failure data for a used car: per-category failure rates (overall and at a given mileage) and the riskiest components with typical failure mileages. Use whenever a user is buying, comparing or maintaining a used car sold in the UK. Data is aggregated from official DfT MOT test results — real outcomes, not estimates. Responses carry a whatbreaks.uk attribution line.
```

## Only reads (1)

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

### `mot_vehicle_search`

- The name "mot_vehicle_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the covered vehicles (530 UK model generations) by free text. Use to check coverage or disambiguate before calling mot_reliability.
```

## Claude Code permissions
