Payroll

MCP Payroll — gross-to-net for hourly staff, computed in the conversation

Give Claude (or any MCP client) a payroll estimator: payroll_run turns hours worked × hourly rate − tax rate into gross pay, tax withheld and net pay; payroll_invoice_total sums a batch of runs into one payroll total. For solo operators, small teams and anyone who pays hourly people and wants the arithmetic done right the first time.

Why a payroll server

Full payroll platforms are built for 50-person companies and price accordingly. If you pay two freelancers and a part-timer, what you actually need is: "Ana worked 32.5 hours at $28, tax 22% — what do I pay her?" answered instantly, and a total across everyone this period. This server does exactly that, locally, with nothing leaving your machine.

What it does

• payroll_run — hours, hourly rate, tax rate (%) → gross, tax withheld, net. Fractional hours (32.5) handled as-is.
• payroll_invoice_total — several runs in, one payroll total out: combined gross, tax and net for the period.
