Claude + Gusto: The Official Connector, Setup and Limits
Yes, Claude has an official Gusto connector. Gusto built it, Anthropic verified it, and it went into Claude’s connector directory in February 2026. Sign in with Gusto and you can ask about payroll and people data in plain English, build reports and charts, and, if Gusto marks your company eligible, run payroll from the chat.
Here’s what the connector does, how to turn it on, where it stops, and how to have Gusto work happen without opening a chat.
What the Gusto connector does
Gusto describes it as “query and analyze your Gusto data.” Its tool list covers:
- Payroll: list payrolls, open a single payroll, check the pay schedule, and (for eligible customers) run payroll.
- People: list employees, their jobs, employments, home and work addresses, departments, and custom fields.
- Contractors: list contractors, contractor payments, and payment groups.
- Time: list time records, read time sheets, and record time.
- Onboarding: check your company’s onboarding status.
In practice that means questions like “what did we spend on payroll last quarter by department?” or “which contractors did we pay more than $5,000 this year?”, answered from live data instead of an export.
Gusto also has an official app in ChatGPT, covered in ChatGPT + Gusto.
How to connect Claude to Gusto
- In Claude, open Customize → Connectors and find Gusto in the directory.
- Click to add it and sign in with your Gusto account. A Gusto admin approves access.
- Start a chat and ask about your payroll or team.
There’s no API key to create. Gusto doesn’t give customers direct API access for their own company, so the connector (and Gusto’s MCP server behind it) is the supported way in.
Where the connector stops
- It works when you ask. Nothing happens until you open Claude and type. A new hire’s signed offer landing in your inbox, or a payroll deadline tomorrow, doesn’t start anything.
- Time off isn’t in the tool list as of September 2026. PTO requests that arrive by email or Slack still get handled by hand.
- It only sees Gusto. The offer letter thread, the manager’s calendar, and the onboarding checklist in your project tool live elsewhere.
So Claude is great for “summarize this month’s payroll by department” and not built for “when a new hire signs, chase their paperwork and book their first-week meetings.”
If you want Gusto work that runs on its own: Carly
Carly connects to Gusto through the same official MCP server, and works from your inbox and calendar as well:
- When a new hire signs, Carly checks their onboarding status in Gusto, emails them what’s still missing, and books their first-week meetings.
- When a PTO request arrives by email, Carly blocks the dates on the team calendar and reminds you to approve it in Gusto.
- The day before payroll, Carly checks what’s still blocking the run and tells you in Slack or by text.
- When a manager asks “who’s on my team and when did they start?”, Carly answers from Gusto without anyone logging in.
Connect Gusto to Carly: at carlyassistant.com/integrations, go to MCP servers and add https://mcp.api.gusto.com. A Gusto admin signs in once to approve. Carly connects to thousands of apps, so your inbox, calendar and Slack come along. AI agents start at $35/month, and steps in a workflow that don’t use AI run free.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
