Kultranz MCP Server — US Salary, Tax & Cost of Living

Remote MCP server (Streamable HTTP) + REST API over real US government data. Live endpoint: https://api.kultranz.com/mcp — free, no auth, no quota.

Five read-only tools a model cannot compute itself:

Tool

What it returns

get_take_home_pay

2026 net pay from gross: federal tax, Social Security (2026 wage base), Medicare, state income tax — all 50 states + DC

compare_cost_of_living

Equivalent salary between two US metros (BEA Regional Price Parities, US=100) with per-category monthly breakdown

get_tax_brackets

Full IRS 2026 bracket ladder + standard deduction, plus any state's rules (none/flat/progressive)

list_metros

The 50 supported metros: price index, median rent, home value, household income

get_salary_percentiles

BLS OEWS annual wages, 10th–90th percentile spread, by occupation × metro

Use it

Any MCP client (Claude, Cursor, Windsurf, Claude Code):

claude mcp add --transport http kultranz https://api.kultranz.com/mcp

npx wrangler d1 create kultranz   # then put the id in wrangler.toml

npx wrangler deploy

All credentials are environment secrets (RAPIDAPI_PROXY_SECRET, MCP_API_KEY, POLAR_ACCESS_TOKEN, POLAR_PRODUCT_ID) — none are required to run the open MCP endpoint.

Data sources: BLS OEWS · BEA Regional Price Parities · U.S. Census ACS · IRS 2026. Methodology: https://kultranz.com/pages/methodology/ · Docs & pricing: https://kultranz.com/pages/api-docs/ Open datasets (CC BY 4.0): us-salary-cost-of-living-dataset · 2026-tax-brackets · cost-of-living-index
