Run compliance checks in Claude Desktop

The `check_warn_compliance` tool takes your layoff event parameters and evaluates them against federal regulations. You pass the affected employee count, location details, and notice timelines to your AI client. Claude processes the data to determine if your reduction in force violates federal notification rules. You get a clear yes or no on legal exposure without opening a separate spreadsheet.

Calculate back pay liabilities

Missing the 60-day notice window creates immediate financial risk. You can run the `calculate_employee_backpay_liability` function to quantify the exact wages owed to affected staff. The MCP multiplies the daily rate of pay by the calendar days in your notice period. You see the total monetary risk in plain text right in your chat window.

Model civil penalty costs via this MCP

Local governments assess fines when companies fail to provide adequate warning. By calling `calculate_civil_penalty_exposure`, your agent estimates the total local fines based on your specific layoff timeline. The output gives HR directors and legal counsel a concrete dollar amount for non-compliance. You can then adjust your termination dates to minimize these exact statutory penalties.
