| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__polymarket__find_traders` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__polymarket__find_traders` |

## Findings

## Only reads (6)

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

### `explain_rating`

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

Description, as the server wrote it:

```untrusted-server-text

```

### `find_traders`

- The name "find_traders" says "find": a word for reading.
- Tag untrusted-input: The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.
