## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `catalog_freshness`

- 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
How current the catalog is: the snapshot served and when it was built.
```

## Only reads (8)

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

### `get_drug`
