Weldable's Workday MCP integration connects your AI agents to your Workday environment, giving them access to HR, payroll, and recruiting data through natural language. Instead of clicking through Workday's deep menu structures to find employee records or check time-off balances, your agent handles those lookups in seconds.
Workday is the system of record for HR at thousands of enterprises. The Workday MCP protocol has gained significant traction since its introduction, with platforms like Zapier, Composio, and Merge all building connectors. Weldable's integration handles the OAuth handshake and token management so your agent stays connected without manual credential rotation.
Use cases
Employee onboarding workflows
When a new hire's start date approaches in Workday, your agent pulls their profile details, department, and manager information. It then creates a welcome channel in Slack, invites the manager and IT contact, and posts a structured onboarding checklist. The agent can also check whether the new hire's equipment request has been submitted and flag any missing items to the IT team.
Time-off balance queries
Managers frequently need to check their team's time-off balances before approving requests. Your agent queries Workday for the requesting employee's PTO balance, checks for scheduling conflicts with other team members who are already out, and returns a clear recommendation. The manager gets an answer in their chat window instead of logging into Workday.
Org chart and reporting chain lookups
Your agent can retrieve reporting relationships from Workday when someone asks "who reports to Sarah Chen?" or "what's the org structure for the engineering department?" It returns the hierarchy with names, titles, and departments. This is especially useful during planning cycles when leadership needs quick visibility into team structures.
Headcount and attrition reporting
Your agent pulls headcount data from Workday by department and compares it against the same period last quarter. It calculates attrition rates, identifies departments with unusual turnover, and formats the results into a report that lands in your leadership Slack channel every month. No one needs to build a Workday report or export a spreadsheet.
Compensation review preparation
During review cycles, your agent pulls compensation data for a manager's direct reports from Workday, cross-references it with market benchmarks in a connected Google Sheet, and generates a summary showing each employee's current comp, tenure, and how they compare to the benchmark. The manager walks into the review meeting with data already organized.
How it works
Connect your Workday tenant through Weldable's authentication flow. Workday uses OAuth 2.0 for API access, and Weldable manages the token lifecycle including automatic refresh. Your agent authenticates as a service account with the permissions you configure in Workday's security settings.
Once connected, make requests in natural language. Ask "show me all open positions in the marketing department" or "what's the PTO balance for the product team?" and Weldable translates your intent into the appropriate Workday REST API calls. Results come back structured and ready for your agent to summarize or pass to another integration.
Tips
Workday's security model is role-based and very granular. The integration service account needs explicit security group assignments for each data domain it accesses (employee data, compensation, time off). Work with your Workday admin to scope permissions tightly. An account with broad access is a compliance risk.
Workday API responses use a nested XML/JSON structure. The data comes back with deep nesting, especially for worker profiles that include multiple positions, compensation plans, and benefit elections. Your agent handles the parsing, but be aware that complex queries may return large payloads.
Tenant-specific endpoints matter. Workday API URLs include your tenant name and the service version (e.g., /ccx/service/{tenant}/Human_Resources/v43.0). Make sure the tenant identifier is correct during setup. Test environments and production tenants have different URLs.
Time-off requests have approval workflows. If your agent submits time-off requests on behalf of employees, those requests still flow through Workday's configured approval chain. The agent creates the request, but managers approve it through their normal process.
