Gross-to-net payroll estimates for hourly staff with common withholding assumptions.
Overview
A local payroll calculator that lets an assistant turn hours worked and hourly rates into gross pay, tax withheld and net pay.
- What you can do
- Compute a single payroll run from hours, hourly rate and tax rate, returning gross, tax withheld and net, with fractional hours handled as given. Sum several runs into one period total with combined gross, tax and net. Calculations are described as running locally in the conversation.
- When to use it
- Useful for solo operators and small teams paying hourly staff or freelancers who want quick gross-to-net estimates and a period total without a full payroll platform.
- Requirements
- Runs as a local process on the user's machine via npx from a GitHub package; desktop client only. No authentication, environment variables or headers are declared.
Installation
In SourceWeft
- Open Payroll in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

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.
Install
Try it
- "Ana: 32.5h at 28/h, 22% tax. Ben: 18h at 35/h, 20% tax. Run both and give me the payroll total."
- "What's the net for 40 hours at 24/h with 18% tax?"
