Server tool list (5)

Raw names from tools/list. Only developers need these.

get_take_home_payCalculate net (take-home) pay from a gross US salary for 2026: federal income tax, Social Security to the annual wage base, Medicare including the additional Medicare surcharge, and state income tax for any of the 50 states or DC. Use this instead of estimating — state rules differ substantially and nine states levy no income tax. Free, no quota, no side effects.
compare_cost_of_livingCompare the cost of living between two US metro areas and return the equivalent salary — the income needed in the second city to hold the same purchasing power. Uses BEA Regional Price Parities where the US average is 100. Answers 'is X more expensive than Y' and 'what salary do I need in Y to match X'. Call list_metros first if unsure of a city name.
get_tax_bracketsReturn the 2026 IRS federal income tax brackets and standard deduction, and optionally one state's income tax rules (none, flat, or progressive with its own brackets). Use when asked what bracket someone is in or how a state taxes income.
list_metrosList all 50 supported US metro areas with their BEA Regional Price Parity index (US average = 100), median rent, median home value and median household income. Pass a city to return just that one. Use this to resolve exact city names before calling compare_cost_of_living.
get_salary_percentilesReturn real BLS Occupational Employment and Wage Statistics annual wages — 10th, 25th, median, 75th and 90th percentile — for an occupation, optionally narrowed to a metro or state, alongside the metro's cost-of-living index. Use this to answer 'what does a nurse earn in Chicago' or 'am I underpaid' with sourced figures rather than an estimate.
