## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `paid_api_info`

- 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
Machine-readable description of the full paid API (endpoints, price, x402 payment).
```

## Only reads (2)

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

### `rug_scan_preview`
