# check_si_working_day

Use this when you need a deterministic Slovenia Slovenia 2026 statutory work-free facts with explicit Monday-Friday planning baseline result. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when slovenia 2026 statutory work-free dates over an explicitly selected Monday-Friday planning baseline. Seven named state holidays are not work-free; no extra Monday or bridge day is invented. Individual shifts, replacement weekly rest, employer/local/sector/school/bank schedules, religious leave, payroll, legal deadlines and future years are not computed. What it computes: Checks a date against the Saturday-Sunday weekend baseline and exact 2026-2026 authority events. Requires explicit mon_fri_planning; seven named state holidays do not add rest. Example user requests: Slovenia: Easter Monday is statutory rest. | Slovenia: Whit Monday is not Whit Sunday. | Slovenia: Science Day is a state holiday without rest. Inputs: date (date); work_schedule (enum). Complete JSON argument examples: {"date":"2026-04-06","work_schedule":"mon_fri_planning"} | {"date":"2026-05-25","work_schedule":"mon_fri_planning"} | {"date":"2026-11-10","work_schedule":"mon_fri_planning"} Outputs: territory, territory_name, weekday, is_working_day, day_type, holiday_names, holiday_kinds, holiday_details, calendar_scope, holiday_policy, substitute_day_policy, calendar_profile, dataset_version, sources, work_schedule, is_state_holiday, is_statutory_non_working_day, is_non_rest_state_holiday, personal_roster_scope, payroll_scope. Formula: planning_workday = weekday AND no statutory_work_free_event Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/slovenia-public-working-day with the same JSON input fields.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "check_si_working_day",

## Why check_si_working_day is rated Low

Even though check_si_working_day only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call check_si_working_day to retrieve information from Calcgrid without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Calcgrid:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "check_si_working_day": {}
  }
}
```
