Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of datetime-ops, so you can see the experience inside your AI.

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

FAQ

Questions datetime-ops owners ask.

  • 01

    Why use an MCP for adding days to a date?

    AI models predict tokens, they don't "compute" calendars. When crossing months (e.g., February 28th to March 1st) or calculating Business Days, LLMs hallucinate dates frequently. This MCP forces exact algorithmic execution.

  • 02

    Are public holidays supported?

    Currently, add_business_days only skips weekends (Saturdays and Sundays). True holiday calculation requires country-specific data which violates the zero-dependency nature of this core utility.

  • 03

    Is this capability secure and local?

    Yes. It executes 100% locally using standard Date parsing built into V8. No cloud dependencies or API calls are used.
