Hardcode Real Dates via MCP Server

Triggering `list_holidays` lets Cursor pull actual public observances into your scheduling functions while you write them. You'll stop faking bank holidays in your test data. The AI agent fetches the exact dates for any country and year, inserting them directly into your arrays or database seed files. Regional logic gets complicated fast. Calling `list_holidays_by_location` isolates dates down to the state or province level. Your editor writes the conditional logic to handle shipping delays in specific territories based on real-world closures, not guesses.

Build Type-Specific Logic

Executing `list_holidays_by_type` separates national bank closures from optional religious observances. Cursor uses this distinction to write precise validation rules for your booking system. You get code that actually knows the difference between a federal holiday and a local festival. Connection issues block development. The `get_account_info` tool lets your AI client check the MCP integration status right inside the IDE. If your auth token expires, the agent tells you immediately instead of generating broken code.

Map ISO Codes and Languages

Running `list_supported_countries` pulls the exact ISO codes required for accurate API routing. Cursor uses these codes to populate your dropdown menus or validation schemas automatically. You skip the manual copy-pasting from external documentation. Localization requires accurate language support. The `list_supported_languages` tool tells your editor exactly which dialects the holiday data supports. The AI drafts your translation mappings using verified, available language codes.

Setup guide

Set up Calendarific MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Calendarific MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Calendarific transactions." If the MCP tools are loaded correctly, Cursor will call the Calendarific tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "calendarific-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }

Common questions about Calendarific MCP in Cursor

Create an mcp.json file in your project root or global settings directory. Add the Vinkius endpoint URL, then enable Agent mode in your chat panel to start using the tools.

Yes. The agent pulls real holiday dates and formats them into JSON, SQL, or whatever structure your test suite requires. You get production-accurate seed data instantly.

It handles state and province-level data without issue. You can ask the agent to build logic specific to local jurisdictions.

The system categorizes every date by type. You can instruct the agent to only fetch national public holidays when generating your scheduling logic.

The integration only accesses external public observance dates and your basic integration status.
