calculate_payroll_run · Sanka MCP Server MCP: Risk & Policy

WHAT IT DOES

What calculate_payroll_run does on Sanka MCP Server

AI agents invoke calculate_payroll_run to trigger actions in Sanka MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why calculate_payroll_run needs a policy

This tool executes a payroll calculation operation—a non-trivial computational process with downstream financial consequences. While the actual payment execution may require separate approval (via 'approve_payroll_run'), the calculation itself modifies state and triggers dependent processes. It is not a simple read operation, not a basic reversible write, and does not directly move money (hence not Financial).

From the tool's definition Tool name explicitly states 'calculate_payroll_run' and description indicates it 'Calculate[s] a payroll run for a period'.
