Calculate business days via this MCP Server

You need to know exactly when a 45-day SLA actually hits. This MCP gives your agent the `business_deadline_tool` to count forward while automatically skipping weekends. It stops you from promising a delivery on a Sunday or a bank holiday. Just ask your AI client to find the deadline for a specific contract. The math happens instantly behind the scenes. You get a hard date back without checking a calendar manually.

Standard calendar math

Sometimes a contract specifies straight calendar days instead of business days. That's where the `calendar_deadline_tool` comes into play. It adds raw days to your start date. You tell Claude the starting point and the duration. The extension handles the basic math and spits out the exact target date. It keeps the context right in your chat window.

Regional holiday awareness

A business day in London isn't always a business day in Tokyo. Your agent can pull the exact local schedule using the `holiday_registry_tool` for any specific region and year. Vinkius manages the connection to these localized registries. You just specify the target country. The calculation adjusts the final date based on that specific local calendar.
