Use A1RO in ChatGPT, Claude and other AI assistants

A1RONovember 2026

A1RO's free Irish employment tools work inside AI assistants. Add one address and your assistant can work out what a temp worker really costs, whether someone is owed a public holiday, and whether a SafeHandle certificate is valid — using A1RO's rates, not a guess.

Add it to Claude

In Claude, open Customize, then Connectors.
Choose Add custom connector and paste https://a1ro.ie/mcp.
Ask, for example: “What does a temp on €15.50 for 39 hours cost me in Ireland, and my margin at €21.50?”

Add it to ChatGPT

Where your ChatGPT plan lets you add apps or connectors by URL, add https://a1ro.ie/mcp as a new connector. No sign-in is needed.

Any MCP client can connect: the server uses Streamable HTTP at https://a1ro.ie/mcp, without authentication. It is listed in the MCP Registry as io.github.A11RO/a1ro.

What it can do

Tool	What it answers
`temp_worker_cost_ireland`	True weekly and hourly cost of a temp or agency worker: pay, holiday accrual, employer PRSI at the right band and date, auto-enrolment, CWPS, and margin. Same figures as the temp worker cost calculator.
`public_holiday_pay_ireland`	Whether a full-time, part-time or casual worker is entitled to a public holiday and how much. Same rules as the public holiday pay calculator.
`irish_public_holidays`	Ireland's public holidays for 2026–2028, or the next ones coming up.
`check_safehandle_certificate`	Whether a SafeHandle manual handling certificate is valid, from its number and the holder's surname. Never returns the holder's name. Same check as a1ro.ie/verify.
`about_a1ro`	What A1RO's products do and cost.

Privacy

The connector has no accounts and stores nothing you send it. Our hosting keeps standard request logs (time, address, path) for security for a short period. Certificate checks only answer valid, expired or not found, with dates. See our privacy policy and terms.

Good to know

Results are general guidance on Irish employment rules, not legal or payroll advice. Rates are checked against Revenue, the Department of Social Protection and the Workplace Relations Commission and change on the dates they take effect. Questions or problems: kevin@a1ro.ie.

Doing this for every worker, every week?

A1ROTime applies each client's pay rules, employer PRSI and holiday pay to every signed timesheet, and prepares the payroll export and draft invoice.
