Run payroll for a household employee end-to-end in a single call. Creates the record, runs all tax calculations (federal, state, FICA, FUTA) with year-to-date tracking, approves the payroll, and kicks off payment processing. Returns the finalized status (processing/pending_funding/completed/sched...

Part of the Nannykeeper MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents invoke run_payroll to trigger processes or run actions in Nannykeeper. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

run_payroll can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

What does the run_payroll tool do? +

Run payroll for a household employee end-to-end in a single call. Creates the record, runs all tax calculations (federal, state, FICA, FUTA) with year-to-date tracking, approves the payroll, and kicks off payment processing. Returns the finalized status (processing/pending_funding/completed/scheduled) plus full tax breakdown, net pay, employer costs, and the payroll ID for reference. Requires a Starter+ subscription. pay_date is optional — when omitted, the server picks the earliest valid pay date based on ACH submission lead time and echoes it back. If supplied and past the submission deadline, the request is rejected with next_valid_pay_date in the error. If pay_date is more than 5 business days in the future on a DD payroll, status=scheduled and the payroll will auto-fire at scheduled_send_at (5 biz days before pay_date). Scheduled responses include is_estimated=true — numbers may shift slightly at fire time if YTD or rate configs change between approve and fire. Direct deposit callers: set confirm_large_payroll=true for totals >$5,000 or any single net pay >$3,000; set confirm_ach_debit=true for first-time DD or if no DD in 30 days. Tip: use preview_payroll first to validate your request and see results before committing. To get your employer_id and employee_id, call the NannyKeeper API: GET /api/v1/employees?employer_id=YOUR_ID (employer_id is visible in your dashboard URL).. It is categorised as a Execute tool in the Nannykeeper MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on run_payroll? +

Add a rule in your Intercept YAML policy under the tools section for run_payroll. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Nannykeeper MCP server.

What risk level is run_payroll? +

run_payroll is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit run_payroll? +

Yes. Add a rate_limit block to the run_payroll rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block run_payroll completely? +

Set action: deny in the Intercept policy for run_payroll. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides run_payroll? +

run_payroll is provided by the Nannykeeper MCP server (@nannykeeper/mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
