Justworks MCP connector

The Justworks connector brings members, payrolls, paystubs, deductions and time off requests into Elaichi, so Claude, ChatGPT, Cursor or the Elaichi Agent can answer questions and update records inside each person's own Justworks access.

  • How it connects. Connects with an API key. The credential goes into a vault nobody reads back.

  • One address. https://api.elaichi.ai/mcp, the same for every user.

  • Their own access. An agent never gets more than the person it acts for.

How to connect

How to connect Justworks to Claude, ChatGPT or Cursor

Two steps, about a minute.

1

In Elaichi

Connect Justworks once

  1. Open Connections, choose Add connection, and pick Justworks.

  2. Optionally set Share with to give a team access, then press Connect.

  3. Supply your own Justworks app, then approve. Justworks needs an OAuth app you register yourself, so bring its client ID and secret. One person does this once for the organization.

The credential is vaulted. Nobody reads it back, not even the AI.

Use cases

What teams do with Justworks through Elaichi

Every one of these runs inside the access the person already has, and lands in the same audit log.

  • HR

    Catch a member record up after a change

    Someone moves teams, changes title or updates a home address, and HR asks the agent to update the Justworks member record from a plain sentence, then confirms what changed.

  • Payroll

    Check a payroll run before it closes

    Pull the latest Justworks payroll, its fees and the paystubs behind it, and ask which members look different from last cycle before anyone signs off.

  • Finance

    Reconcile payroll fees against the bank account

    List Justworks payrolls and payroll fees for the month alongside the company bank account details so month-end close starts from live figures rather than exports.

  • Benefits

    Set up and correct deductions in bulk

    Create a new deduction for a member, update a batch of deductions when a plan changes, or cancel one that was entered twice, all from Justworks deduction types you already use.

  • People ops

    Answer who is out and what they have left

    See open Justworks time off requests for the week, check them against each policy, and run a time off balance report before approving a long leave.

  • Leadership

    Get a headcount picture by jurisdiction

    Ask how many Justworks members sit in each state or jurisdiction, which custom fields are filled in, and what the company business info currently says.

Try asking

  • “Which time off requests are still waiting on approval this week?”
  • “Show me payroll fees for the latest payroll run.”
  • “Update Maria Lopez's title to Senior Account Manager.”

FAQ

Frequently asked questions

How do I connect Justworks to Claude?

Connect Justworks in Elaichi first: Justworks asks you to register an OAuth application inside Justworks itself, so one person brings that client ID and secret into Elaichi once, and nobody has to do it again. Then in Claude go to Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp as the endpoint. Claude signs you in to Elaichi and Justworks appears alongside your other connected applications.

Does Justworks work with ChatGPT and Cursor as well as Claude?

Yes. Once Justworks is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, any other MCP client and the Elaichi Agent. You connect Justworks once and every client you use picks it up.

What can an AI agent actually do with my Justworks data?

With Justworks connected, an agent can look up members and their custom field values, update a member record, list payrolls, payroll fees and paystubs, create, update or cancel deductions, and show time off requests, policies and balance reports. It can also read company details such as jurisdictions, business info and bank account information. Short concrete asks work best, like asking for open time off requests this week rather than a long paragraph.

Does connecting Justworks give the AI access to everyone's pay and tax details?

No. Every call into Justworks runs as the person who signed in, so the agent sees only the members, paystubs and deductions that person can already see in Justworks. Elaichi can narrow that access further with roles and restrictions, and it can never widen it beyond what Justworks itself allows.

Can my team share one Justworks connection?

Yes. One person connects Justworks in Elaichi and shares the connection with a team, so nobody else ever handles the client ID or secret. Each teammate still signs in to Elaichi as themselves, so every payroll lookup or member update in the audit log carries their own name.

Can I stop an agent from deleting or changing things in Justworks?

Yes. In Elaichi you restrict Justworks actions individually, so a team can be allowed to read payrolls and paystubs while updating members or cancelling deductions is switched off. A restricted action is never advertised to Claude, ChatGPT or Cursor at all, so no prompt can reach it.

What happens to a Justworks connection when someone leaves?

When a person is offboarded in Elaichi, their access to Justworks through every client ends at once. A Justworks connection they shared keeps working for everyone else on the team. If you want it gone entirely, disconnecting Justworks once in Elaichi removes it from Claude, ChatGPT, Cursor and every other client together.

Does the Justworks MCP connector work with Gemini, Codex, Claude Code or other MCP clients?

Yes. Justworks is reached over the same MCP endpoint every client uses, so anything that speaks MCP can call it — Gemini, Codex, Claude Code, Windsurf, Cline, Zed and OpenCode among them — alongside Claude, ChatGPT, Cursor, and the Elaichi Agent. The tools on offer and the access behind them are identical whichever client asks. Only the setup screen differs.
