Passed: Connections are encrypted (HTTPS).
Passed: No hidden instructions found in tool text.
Safety labels
Warning: 134 of 344 tools do not say whether they can change things.
MCP lets a server label each tool as read-only or destructive, so clients can ask the user before risky calls. Unlabelled tools are treated as able to change things.
