Full read-write Claude connector for Gusto

Have Claude onboard hires and prep payroll in Gusto

Stop clicking through forms to add a hire, change a pay rate, or stage a payroll run. Claude does the people-ops record-keeping where your data already lives, and the sensitive steps wait for your sign-off.

Gusto is a payroll, benefits, and HR platform that small and midsize teams run their people operations on. People want Claude to do more than read employee records: to onboard new hires, update compensation, manage time off, and prepare payroll inside Gusto.

What is a Gusto MCP server?

A Gusto MCP server is a small hosted service that exposes Gusto'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 Gusto's current connector do today?

Gusto publishes an official MCP server, so Claude can connect and read your account today. The catch is that the native tools are read-only. Claude can look up employees, payroll, and time off and analyze them, but it cannot act. Onboarding, compensation changes, and payroll prep stay outside its reach until you add write access.

What does full read-write Gusto access unlock?

A custom connector adds the write actions the native read-only tools leave out. Claude can add a new hire and start onboarding, update an employee's pay rate, file or approve time-off requests, adjust deductions, and stage a payroll run for your review. The record-keeping that used to mean clicking through forms happens where your people data already lives.

  • Create a new employee and kick off their onboarding flow
  • Update an employee's compensation or pay rate
  • Enter or approve a time-off or PTO request
  • Adjust benefit deductions or contribution amounts for an employee
  • Stage a payroll run with hours and earnings for your review
  • Update an employee's job title, department, or home address

Can Claude add a new employee and start onboarding in Gusto?

Adding a new employee and starting onboarding in Gusto is exactly what a custom read-write connector enables. Claude creates the employee record and kicks off the onboarding flow through a scoped write tool, then can set their job title, department, and home address, all tied to your account's existing permissions.

Can Claude update an employee's pay rate in Gusto?

Updating an employee's pay rate in Gusto is a scoped write action Claude can run for you. It can adjust compensation, change deductions or contribution amounts, and revise job details. If your own role cannot change pay, neither can Claude through the connector, since it inherits your permissions.

Can Claude run payroll in Gusto?

Claude can prepare a payroll run in Gusto by gathering hours and staging earnings for your review, but submitting it is a separate, gated action. The run only goes through after you confirm it, so Claude never pushes payroll on its own. You decide which steps are automatic.

How a Gusto connector works

We build a small MCP server that authenticates to Gusto with OAuth and the narrowest scopes the work needs. Read tools (look up employees, view payroll) and write tools (create employee, update pay, file time off) are separated, and sensitive actions like submitting a payroll run require your confirmation. Claude only ever has the access your own Gusto account already has.

Frequently asked questions

Can Claude add a new employee and run onboarding in Gusto?
Yes, with a custom Gusto connector. The official MCP server is read-only, so it can show you an employee but cannot create one. Claude creates the record and starts onboarding through a scoped write tool, tied to your account's permissions, that the native read-only tool set does not provide.
Will Claude submit a payroll run without my approval?
No. Submitting payroll is a separate, gated write action. Claude can gather hours, stage earnings, and prepare the run, but it is only submitted after you review and approve it. You decide which steps are automatic and which require an explicit confirmation.
Does a Gusto connector get more access than I have?
No. The connector authenticates as your account through OAuth and inherits your existing permissions. If your role cannot change compensation or run payroll, neither can Claude through the connector. It never grants more access to Gusto than you already have.
