```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 destructive). Whether a call also works without credentials was not tested: tools are never called.

https://humanitix.usefulapi.io/mcp: tools/list returned 15 tools to an anonymous client, including humanitix_check_in_ticket (destructive), humanitix_check_out_ticket (destructive), humanitix_create_event (destructive), humanitix_update_event (destructive)
