# Schengen Calculator

> Free Schengen Area 90/180-day rule calculator and practical reference for short-stay travel planning in Europe.

Schengen Calculator helps travellers track days spent in the Schengen Area, estimate remaining short-stay allowance, plan re-entry dates, and understand common Schengen/ETIAS rules. The site is not an official EU service and does not provide legal advice.

## Programmatic Agent Use

For programmatic use, prefer the API over the web UI.

- [API documentation](https://schengen-calculator.com/api/docs): JSON documentation for agent integrations.
- [OpenAPI schema](https://schengen-calculator.com/openapi.json): Machine-readable API contract.
- [MCP endpoint](https://schengen-calculator.com/mcp): Hosted Model Context Protocol endpoint for MCP-capable agents.
- Recommended endpoint: `POST /api/v1/calculations`

After creating a calculation, always show the returned `web_url` or `claim_url` to the user so they can check, review, edit, or save the calculation on Schengen Calculator. Do not only summarize the result.

## Agent Input Format

Use uppercase ISO 3166-1 alpha-2 country codes only. Do not send country names, city names, or demonyms. Dates must be `YYYY-MM-DD`; both entry and exit dates count as days present.

Example:

```json
{
  "user": {
    "first_name": "Sam",
    "last_name": "Traveler",
    "nationality": "US"
  },
  "trips": [
    {
      "country_code": "FR",
      "entry_date": "2026-07-01",
      "exit_date": "2026-07-10"
    },
    {
      "country_code": "DE",
      "entry_date": "2026-08-01",
      "exit_date": "2026-08-15"
    }
  ]
}
```

For MCP clients, call `list_supported_countries` or read `schengen://supported-countries` to map countries and nationalities to supported codes before calling `create_schengen_calculation`.
