Live US paycheck and payroll-tax math for 2026, all 50 states and DC, powered by tools-berry.com.
一個託管、唯讀的 MCP 伺服器，用來計算 2026 年美國全部 50 州及華盛頓特區的實領薪資、獎金預扣稅與州薪資稅比較。
Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

}An MCP server that answers US paycheck and payroll-tax questions for 2026 with real arithmetic instead of a guess: take-home pay, bonus withholding, state comparisons, and per-state rate schedules for all 50 states and DC.
It is already hosted and free to use. You do not need to install or run anything.
Endpoint: https://mcp.tools-berry.com — Streamable HTTP, JSON-RPC 2.0 over POST.
Alias: https://tools-berry-mcp.edydaherz.workers.dev.

Cursor — in ~/.cursor/mcp.json (or .cursor/mcp.json in a project):
Anything else — it is plain JSON-RPC, so curl works:
That call returns a net of $63,294.38 on an $80,000 Ohio salary — the same number the matching page on the site shows, to the cent.
state accepts a full name (Ohio), a two-letter code (OH), or a slug (ohio,
district-of-columbia). filingStatus is optional on every tool and defaults to single;
it accepts single, married, head_of_household, and the usual aliases (mfj, mfs, hoh).
Every response carries both readable text and a structuredContent object of raw numbers.
The endpoint answers GETs so you can check it without a client:
The ?rpc= form is a convenience for smoke tests, not part of MCP. It exists because some
networks block *.workers.dev or drop POST probes, and a server nobody can reach is
indistinguishable from a server that is down.
tools.js imports src/engine/paycheck-engine.js and
src/engine/bonus-tax.js directly and feeds them the same data files the public pages are
built from. Nothing is re-derived for the MCP layer; that layer only shapes input, picks a
link, and formats text. test/test-mcp-server.js asserts the server's answers equal the
engine called directly, to the cent, across all 51 jurisdictions — so the server cannot
quietly drift away from the site.initialize, tools/list,
tools/call, plus ping and the empty resources/list / prompts/list probes, so it is
implemented by hand in mcp.js rather than pulling in an SDK. npm install is a no-op;
npm test runs on plain Node.Tax year 2026, all 50 states plus the District of Columbia. Covered: federal income tax, Social Security and Medicare (including the additional 0.9%), state income tax, and state employee payroll programs such as SDI and PFML. Figures are withholding-style estimates for a single job with no pre-tax deductions and no credits beyond the standard deduction. Local and city income taxes are not included. This is not tax advice and it is not a filed return.
get_state_rates returns a source field naming the statute or department schedule each
state's figures come from, so any number here can be traced back.
Provenance and refresh. The engine and the two data files are maintained on tools-berry.com and mirrored into this repository. The hosted server is deployed from the site's own repository, so this repo is the readable, reusable copy rather than the deployment source. When rates change on the site, the mirror is refreshed here. If you need a guarantee that you are on current figures, call the hosted endpoint.
If figures or code from here feed something you publish, please cite tools-berry.com. That request is the whole business model behind giving the engine away.
You do not need to — the hosted instance is free and open. But if you want your own copy:
It is a single Cloudflare Worker with no bindings and no secrets. wrangler.toml has the
custom-domain block commented out; uncomment it and point it at a hostname you control, or
just use the workers.dev URL wrangler prints.
