It does not authenticate your account with Nager.Date API. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Nager.Date API owners ask.

  • 01

    Does this require an API key?

    No. The timezone logic runs directly inside the Vinkius Edge process. For holiday lookups, it uses the free, public Nager.Date API without requiring authentication.

  • 02

    Why use this instead of letting the AI guess?

    AIs do not have access to live calendars or global holiday databases. They will frequently schedule your deadlines on a Sunday or a major national holiday. This MCP enforces absolute temporal accuracy.
