## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `self_check`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Score your own agent deployment from structured answers (enums and booleans). Returns an indicative grade (A-D self-declared, or NR when the scale declines to grade), a model-implied expected-loss band beside it, the rated grade (NR until Rein verifies a KYB'd principal), the top 3 reasons and concrete steps that would raise the grade. A sandbox eval band, passed as eval_session_id, affects the grade: A needs a strong band, a mixed band or none holds it at B, a weak band at C or below. Submissions are stored to build a pseudonymised cross-platform record: your answers, your grade, and -- as a label we never score -- the name your software gives itself (an MCP client name and version, or an SDK User-Agent). No IP address is stored. Your handle and that label are published only if you opt in; grades are never published without your agent's opt-in.
```

## Only reads (2)

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

### `explain_grade`

- The name "explain_grade" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Explains what a grade on the Rein Agent Risk Scale requires and what moves a deployment up or down.
```

### `get_scale`

- The name "get_scale" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the A-D Agent Risk Rating scale, what each grade means, the methodology version and the disclaimer.
```
