Jp Payroll MCP
duet0912 · MCP server
Gives your AI assistant Japanese payroll, social insurance and labour law calculations from published rate and tax tables. It works out payslips, bonuses, overtime and withholding tax, estimates resident tax, and judges questions such as whether a monthly change notification is due or which months a childcare leave exempts. It judges whether a filing is needed rather than producing the filing, and offers 30 tools through a hosted remote endpoint or a local process.

Why it's useful
Japanese payroll rules have counter-intuitive edge cases, so your agent works from calculated figures and sees the provisions behind each one.
What you could do with it
- Ask what happens to March social insurance premiums when an employee leaves on 31 March.
- Check whether raising a base salary from 280,000 to 320,000 yen in April calls for a monthly change notification.
- Calculate overtime pay with the higher rates for work beyond 60 hours a month, on legal holidays and late at night.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Data handling disclosed
- finding
- no statement of what it reads, writes or sends (README.md)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.4.5, the file with digest sha512-pmiCYtm4rLxjGSb4HA3bgZViludW0d6a9NZuQ3MCNEOrzf/1hnurO3E/YATSfhKGgvuWcfRoRFYbe5Wp7f/IJw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- No auth declared. Its hosted endpoint, as the official MCP registry lists it, does not say it asks for a key. That is what the listing declares, not a finding that it has no protection.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
The badge, if this is your listing
It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
