| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__verrow__watch_parcel` `mcp__verrow__watch_town` |

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 14 tools that change things (1 destructive, 1 irreversible, 12 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.verrow.ai/mcp: tools/list returned 24 tools to an anonymous client, including cancel_watch (destructive), topup_credits (irreversible), check_coverage (write), create_api_key (write), check_use_allowed (write) and 9 more
