  • Passed: Connections are encrypted (HTTPS).

  • Passed: No hidden instructions found in tool text.

Safety labels

  • Warning: 31 of 31 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.

    • pmid-ok
    • utc-time
    • timezone
    • validate-json
    • normalize-url
    • inspect-robots
    • domain-shape
