- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (1 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.potarix.com/mcp: tools/list returned 9 tools to an anonymous client, including topup_credits (irreversible), start_checkout (write)
