- **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 (2 destructive). Whether a call also works without credentials was not tested: tools are never called.

https://onfido.usefulapi.io/mcp: tools/list returned 14 tools to an anonymous client, including onfido_create_applicant (destructive), onfido_update_applicant (destructive)
