## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `scan_text`

- 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
Check text your agent is about to read (a web page, email, document, tool result or another agent's message) for prompt injection before acting on it. Returns risk_score 0-100, verdict (safe | suspicious | malicious), categories and the exact matching spans. Free tier: up to 2000 characters; longer text, URLs and MCP tool definitions via the paid x402 endpoint.
```
