`working_days`	integer	Yes	Signed number of official working days to add; the start date is excluded when non-zero. Negative values move backward. Unit: working days.

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs add_china_working_days 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 add_china_working_days, this is the rule to start with:

add_china_working_days Rate-limited

add_china_working_days stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

What does the add_china_working_days tool do? +

Use this when you need a deadline or settlement date a stated number of mainland China national working days before or after a 2024-2026 date.

Do not use this when you need calendar days, a sector-specific settlement calendar, a local holiday calendar, or a result outside the 2024-2026 coverage. What it computes: Adds or subtracts official mainland China working days, skipping holiday periods and ordinary weekends while counting State Council-designated weekend makeup workdays.
