## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `drift-detector`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Detects differences between an actual API response and an expected JSON schema. Reports missing_required (error), type_mismatch (error), enum_violation (error), missing_optional (warning), unexpected_field (info). Recurses into nested objects.
```

## Only reads (2)

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

### `breaking-change-analyzer`

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

Description, as the server wrote it:

```untrusted-server-text
Analyzes breaking changes between two schema versions. Detects: field removal, type changes, newly required fields, enum value removal, constraint tightening.
```

### `schema-validator`

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

Description, as the server wrote it:

```untrusted-server-text
Validates if data conforms to a JSON schema. Returns valid:true/false and an error message on failure.
```
