How to Use the Workday MCP in OpenAI Agents SDK

Q: How can I check an employee’s time off balance using Workday and OpenAI Agents SDK?

You call the gettimeoffbalances tool. The agent takes a worker ID as input, hits the MCP Server, and gets back structured JSON with their current PTO totals. It's immediate.

Q: Does this Workday integration support searching for workers using OpenAI Agents SDK?

Absolutely. Use listworkers with a search parameter. You can filter by name, employee ID, or other attributes you have on hand. It’s basically an advanced directory lookup.

Q: If I need to check a specific cost center's data, how do I use Workday with OpenAI Agents SDK?

You use the general queryresource tool. You pass 'costCenters' as an example resource type. The agent figures out the right API call to pull that specific financial grouping.

Perplexity

Run Complex Workday Reports on the MCP Server

You can run specific, pre-defined reports from Workday using the `execute_raas_report` tool. The results come back clean JSON, letting your agent immediately parse data like payroll or time off without extra steps. This is perfect for building specialized workflows. You pass parameters directly in the URL, so the report context stays attached to the job. It keeps everything tidy.

Get Worker Details and Time Off Balances with Workday

Need a quick profile on an employee? Use `get_worker` for detailed records, or check current PTO status via `get_time_off_balances`. The agent knows exactly which worker you're talking about because you provide the specific ID. It also tracks pending time off requests using `get_time_off_requests`, so your agent doesn't just report balances; it reports who needs to take action first.

Search and List Organizational Structure Data

Don't want to manually map out departments? The MCP Server gives you the `list_supervisory_orgs` tool, showing organization names, managers, and current headcounts. Plus, you can list all open job requisitions using `list_job_requisitions`. If you need to find a specific department or resource type, the general `query_resource` handles everything from locations to cost centers.

Setup guide

Set up Workday MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Workday tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Workday tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Workday tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Workday Agent",
            instructions="You have access to Workday tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())
