What check_my_working_day does on Calcgrid
AI agents call check_my_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.
| Parameter | Type | Required | Description |
|---|---|---|---|
date | string | Yes | Gregorian date in the pinned 2027 coverage. |
division | string | Yes | Required federal-territory/state code: KUL, LBN, PJY, JHR, KDH, KTN, MLK, NSN, PHG, PRK, PLS, PNG, SBH, SWK, SGR or TRG. |
Parameters from the server's own tool schema.
Why check_my_working_day is rated Low
Even though check_my_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.
Attacks that exploit this kind of access
The rule that runs check_my_working_day safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Calcgrid, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For check_my_working_day, this is the rule to start with:
check_my_working_day is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Calcgrid, apply this rule, and every check_my_working_day call is checked against it from then on.
Questions about check_my_working_day
Use this when you need a division-specific Malaysian public-holiday 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 the division is unknown, or you need an employer, bank, exchange, school or inferred replacement-day calendar. What it computes: Checks a Malaysian date with a required federal-territory/state division, BKPP/JPM's 2027 public-holiday table and division weekly-rest baseline. Example user requests: Is 2027-02-08 a working day in Kuala Lumpur? | Check 2027-06-06 in Terengganu. Inputs: date (date); division (enum). Complete JSON argument examples: {"date":"2027-02-08","division":"KUL"} Outputs: territory, territory_name, division, division_name, weekday, is_working_day, day_type, weekend_days, holiday_names, holiday_observed, rest_day_policy, substitute_day_policy, calendar_scope, calendar_profile, dataset_version, sources. Formula: is_working_day = division weekly baseline and no applicable BKPP event Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/malaysia-working-day with the same JSON input fields. Do not guess another /api/* path. Docs: https://tttkmbb.com/everyday/malaysia-working-day.md.
