Configure the Gusto MCP Server

Updated 1 min read

Overview

Gusto operates an official hosted MCP server for payroll, employee, contractor, and company data. Access is authorized through OAuth with dynamic client registration.

1. Add the MCP server to your gateway config

In the mcp_servers section of your gateway configuration add the following entry:

  - name: gusto
    description: "Gusto official hosted MCP server."
    url: https://mcp.api.gusto.com
    transport_type: streamablehttp
    authentication:
      type: oauth
      grant_type: authorization_code
      issuer: "https://mcp.api.gusto.com"
      scopes:
        - mcp
      dcr_enabled: true
      redirect_uri: "<CALLBACK_URL>"

Replace the placeholder value:

  • <CALLBACK_URL> — your Dtwo gateway’s OAuth callback URL, found in the Configuration section for your gateway in the Dtwo UI.

2. Deploy and verify

Save the configuration and deploy the gateway.

Then, in your AI client, ask it to authorize Gusto via the gateway. This opens the Gusto login screen — sign in as the user whose permissions the agent should inherit, and approve the consent prompt. Once authorized, confirm the server’s tools appear and run a quick read-only call, such as listing employees, to make sure the connection works.
