What check_bd_working_day does on Calcgrid
AI agents call check_bd_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 Bangladesh's pinned 2026 government/public-office holiday coverage over a Friday-Saturday weekend. |
Parameters from the server's own tool schema.
Why check_bd_working_day is rated Low
Even though check_bd_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_bd_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_bd_working_day, this is the rule to start with:
check_bd_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_bd_working_day call is checked against it from then on.

Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery.
