Full read-write Claude connector for Justworks
Have Claude onboard hires and file PTO in Justworks
Stop tab-switching to run HR admin by hand. Claude works inside Justworks itself: starting onboarding, recording time-off, and updating pay details where the employee record already lives, with sensitive changes waiting for your approval.
Justworks is a PEO and HR platform that handles payroll, benefits, and onboarding for small and mid-sized teams. People want Claude to do more than look up an employee record: to start onboarding, file PTO, and update pay details inside Justworks itself.
What is a Justworks MCP server?
A Justworks MCP server is a small hosted service that exposes Justworks's data and actions to Claude over the Model Context Protocol, so Claude can people, time, and pay inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can Justworks's current connector do today?
Today, Justworks has no first-party Claude or MCP connector we are aware of, so Claude cannot read or write your Justworks data out of the box. A custom connector, built on whatever API or scoped access your plan allows, can add read and write actions with scoped, human-in-the-loop controls so Claude works inside Justworks, not beside it.
What does full read-write Justworks access unlock?
Full read-write Justworks access lets Claude kick off an onboarding for a new hire, record a time-off request, update direct-deposit or compensation details, and pull a payroll summary, all after you approve. The HR admin work that used to mean tab-switching happens where the employee record already lives.
- Start an onboarding workflow for a new hire and pre-fill their details
- File or approve a paid-time-off request for an employee
- Update an employee's compensation or direct-deposit information
- Add or update a dependent on someone's benefits enrollment
- Pull a payroll run summary and flag entries that need review
- Mark an employee as terminated and start offboarding once you approve
Can Claude start onboarding a new hire in Justworks?
Yes. With a full read-write Justworks connector, Claude can kick off an onboarding workflow for a new hire and pre-fill their details, so the record is built where it belongs. It runs against the access your own Justworks account already has, never broader, and you confirm before anything commits.
Can Claude file a time-off request in Justworks?
Claude can file or approve a paid-time-off request for an employee, then pull a payroll run summary and flag entries that need review. Read tools and write tools stay separate, so routine HR admin flows freely while the work happens inside Justworks instead of beside it.
Can Claude change compensation or terminate someone in Justworks?
Claude can prepare a compensation or direct-deposit change and start offboarding a terminated employee, but those are gated actions. It shows you exactly what it will do and nothing commits until you approve, so pay edits and terminations never run automatically.
How a Justworks connector works
We build a small MCP server that connects to Justworks through scoped API or database access, using only the narrowest permissions the work needs. Read tools (look up employees, pull payroll summaries) and write tools (onboard, file PTO, update pay) are kept separate, and sensitive or outbound actions like terminating an employee or changing pay require your confirmation. Claude never gets more access than your own Justworks account already has, and access can be locked to an allowlisted IP range.
