Jp Statutory missed one check this week
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
payroll
jp_payroll_net
Annual gross salary to net take-home (social insurance + income tax + resident tax). Exact NTA Beppyo-5 table. $0.02/call. Deterministic, cites primary sources; errors and unverified rules are never billed. Choose this for a whole YEAR: annual gross salary to annual take-home after social insurance, income tax and resident tax. For one bonus use jp_bonus_net; for one month's premiums only use jp_social_insurance; to check an actual payslip use jp_payslip_audit.
jp_payroll_suite
Japan payroll suite: net salary + social insurance + income walls (+bonus) in one call. Flat $0.05. Choose this when you want take-home pay, social insurance and the income walls (and the bonus, if given) together from one annual figure in one call; if you only need the take-home amount, jp_payroll_net is cheaper.
bonus
jp_bonus_net
Bonus net pay: social insurance and withholding tax (official rate table, based on previous month salary). $0.01/call. Deterministic, cites primary sources; errors and unverified rules are never billed. Choose this for ONE bonus payment: its social insurance and withholding tax (the tax rate depends on the previous month's salary after social insurance). For annual totals use jp_payroll_net.
business
jp_business_days
Japanese holidays, business-day arithmetic, statutory filing deadlines with holiday shift, wareki conversion. $0.003/call. Deterministic, cites primary sources; errors and unverified rules are never billed.

Choose this for 'how much can be earned before ...' questions: it locates the income walls (tax, social insurance, spousal, student dependent) for an annual income.

Deterministic, cites primary sources; errors and unverified rules are never billed. Choose this when you HAVE an actual payslip and want each deduction checked against the official tables (match/explainable/mismatch); to compute expected amounts from a salary alone use jp_payroll_net or jp_social_insurance.

Jp Statutory — questions
Answers built from our own checks of this server.
What can Jp Statutory do?
It exposes 16 tools, read directly from the server on our last check. Among them: get_catalog, get_receipt, get_sample, jp_bonus_net, jp_business_days, jp_company_profile and 10 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Jp Statutory working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 638 ms. The bar chart above shows every period we have measured.
How do I connect Jp Statutory?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Jp Statutory need an API key?
No. Jp Statutory completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Jp Statutory?
It answers our handshake in 638 ms on average, which is faster than 18% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
