How to Use the Calendarific MCP in Windsurf

Q: Can Windsurf Cascade check state-level holidays using Calendarific?

Yes, Cascade uses the listholidaysbylocation tool to check regional dates. It passes the country and state parameters automatically when it analyzes your local sprint plans. You don't need to feed it the raw parameters yourself.

Q: What file do I edit if the Windsurf UI setup fails?

You can edit your /.codeium/windsurf/mcpconfig.json file directly. Add the server entry under the mcpServers key with your Vinkius URL. Save the file, and the IDE will reload the connection.

Let Windsurf Cascade autonomously map out your project schedules and shipping deadlines around global holidays.

Cascade Holiday Mapping in Windsurf

This MCP Server exposes `list_holidays` directly to Windsurf, giving Cascade the power to check calendar conflicts when planning project milestones. Your agent scans your local workspace, reads your target launch dates, and automatically runs the holiday query to verify your team is active. If Cascade spots a conflict, it doesn't wait for your permission to fix it. It chains the `list_holidays_by_location` tool to check regional differences, adjusts the task list inside your workspace, and updates your markdown roadmap in one shot.

Regional Shipping Verification

The `list_holidays_by_type` tool lets Windsurf filter down to religious or local observances that might delay your regional shipping runs. Cascade scans your distribution lists, identifies target states, and queries regional calendars to keep your delivery estimates accurate. Because Cascade operates autonomously, it maps out the entire regional shipping calendar without you writing a single API call. It updates your JSON configuration files with the correct dates and flags upcoming freight delays before they hit your operations.

Global Market Localization Setup

The `list_supported_countries` tool lets Windsurf configure regional locales using this MCP Server. Cascade reads your target market list, pulls the correct ISO codes, and populates your localization files with accurate holiday metadata. You don't have to look up ISO codes or language mappings yourself. The agent runs `list_supported_languages` to match the exact localized strings, edits your translation files, and commits the updates straight to your workspace.
