Perplexity

Run Payroll Reports

Need to process payroll data? Use `get_payroll_results` within a multi-step workflow. If the initial attempt fails, Mastra AI can automatically retry using an exponential backoff strategy. This is critical for finance operations. The agent handles the failure logic around retrieving sensitive employee pay data, giving you reliable execution every time.

Query Org Structures

Mapping out who reports to whom? The `list_supervisory_orgs` tool retrieves organizational names, managers, and headcounts. Your agent can use this result in a conditional branch. For example: if the report shows zero direct reports for a manager, the workflow automatically skips sending an alert.

Manage Worker Records

To manage worker records, your agent uses tools like `get_worker` and `list_workers`. These aren't just lookups; they are steps in a larger process. You can check if an employee exists before initiating an action. It’s perfect for building compliance checks: first verify the worker via `get_worker`, then proceed with updating their record.

Setup guide

Set up Workday MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Workday tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "workday-mcp-client",
  servers: {
    "workday-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Workday Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Workday tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Workday transactions"
);
console.log(result.text);

Common questions about Workday MCP in Mastra AI

Mastra AI handles retries automatically. If fetching time off balances via `get_time_off_balances` fails due to a temporary network blip, the workflow simply tries again later.

Yes. You can set up a step that calls `list_job_requisitions`. The entire process—from calling the tool to getting the list of open roles—is treated as one reliable, automated workflow.

It supports everything: worker details (`get_worker`), PTO history (`get_time_off_requests`), and resource queries like cost centers via `query_resource`. It's built for complex, multi-domain HR logic.

It uses a dedicated MCP Server connection that allows defining specific tool calls. You can even require human approval before the agent runs powerful commands like updating payroll data.

The server touches worker organizational structure, including department names and manager IDs via `list_supervisory_orgs`. It also handles sensitive employee identifiers needed for all API calls.
