Overview

What it does

hourledger-mcp gives AI assistants the same tested pay-rules engine that powers hourledger.com. Ask a messy real-world question — "I worked Monday to Thursday 7am–5pm at $19/hour in Nevada, what's my gross pay?" — and the assistant calls the calculator instead of doing payroll arithmetic from memory.

Tools

`calculate_work_hours`

Clock in/out entries with unpaid breaks, an hourly rate, and a ruleset — returns the per-day and total regular / overtime / double-time split plus gross pay.

Ruleset	Rule
`federal`	1.5× past 40 h/week (FLSA)
`california`	1.5× past 8 h/day, 2× past 12 h/day, 7th-day rule, no pyramiding
`alaska`	1.5× past 8 h/day or 40 h/week
`colorado`	1.5× past 12 h/day or 40 h/week (COMPS Order)
`nevada`	daily 8 h rule only below 1.5× minimum wage — applied automatically from the rate (NRS
608.018)

Handles overnight shifts, per-entry rounding (exact / 5 min / 15 min / 0.1 h), and configurable workweek start day. Every pay rule is covered by the automated test suite (27 tests in the repo).

`time_and_a_half`

An hourly rate and overtime hours — returns the 1.5× rate and total overtime pay.

Try it

"What's time and a half of $24/hour, and what would 6 overtime hours pay?"
"I work in Nevada, Mon–Thu 7am–5pm. Compare my weekly pay at $15/hour vs $20/hour." — watch daily overtime appear below Nevada's $18 cutoff and disappear above it.
"I'm in California at $22/hour. Monday I worked 6am–7pm, Tuesday 10pm–6am overnight. Break down my regular, overtime, and double time pay."
