# check_india_central_working_day

Use this when you need a deterministic 2026 central-government office baseline and can specify Delhi/New Delhi versus outside Delhi. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when you need a state, Union Territory, bank, employer, school, exchange, or an outside-Delhi locally selected optional-holiday calendar. What it computes: Checks a 2026 date against the Department of Personnel and Training central-government holiday schedule, preserving Gazetted and Restricted distinctions. Example user requests: Is 2026-10-20 a working day for India's central government office in Delhi? | Is 2026-08-28 a guaranteed closure or only a restricted holiday option outside Delhi? Inputs: date (date); office_scope (enum). Complete JSON argument examples: {"date":"2026-10-20","office_scope":"delhi_new_delhi"} | {"date":"2026-08-28","office_scope":"outside_delhi"} Outputs: territory, territory_name, office_scope, office_scope_name, weekday, is_working_day, is_guaranteed_non_working_day, day_type, gazetted_holiday_names, restricted_holiday_names, restricted_holiday_available, calendar_scope, rest_day_policy, restricted_holiday_policy, selection_policy, substitute_day_policy, calendar_profile, dataset_version, sources. Formula: is_working_day = India Saturday/Sunday baseline and no applicable Gazetted holiday; Restricted holidays remain options Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/india-central-working-day with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/everyday/india-central-working-day.md

## Why check_india_central_working_day is rated Low

Even though check_india_central_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_india_central_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_india_central_working_day": {}
  }
}
