How to Use the Workday MCP in Google ADK

Q: How do I check pending time off requests for a worker in Workday with Google ADK?

Simply call the gettimeoffrequests tool. The agent needs the worker ID, and it returns structured data showing all outstanding or scheduled time-off requests for that individual.

Q: What specific payroll results can I pull from Workday using Google ADK?

You use getpayrollresults. The tool requires the worker's identity to run, and it returns a detailed JSON payload of their most recent pay period data. It’s designed for direct consumption by your agent.

Q: How can I find open job openings in Workday using Google ADK?

The listjobrequisitions tool handles this directly. Your agent calls it, and it gives a list of all currently open roles across the company that need filling.

Q: If I search for employees in Workday using Google ADK, what attributes can I filter by?

You use listworkers. The search parameter allows filtering by name, employee ID, or other key worker attributes. It's a flexible way to narrow down large lists of people.

Perplexity

Execute Complex Reporting via the MCP Server

You can call `execute_raas_report` to get reports from Workday, and the results show up in JSON format. This is better than dealing with raw files because your Google ADK agent can process it instantly. The report's URL even accepts prompt parameters, meaning the context of the request stays locked into the resulting data set.

Get Worker Info and Organizational Structure Data

Need to know who works where? Use `list_supervisory_orgs` to get names, managers, and headcounts. For individual employee details, run `get_worker`. The agent can then cross-reference this data with job requisitions listed by `list_job_requisitions`. This gives a full picture of the company's current staffing structure.

Query Any Workday HR Resource using MCP Server

The general `query_resource` tool lets your agent access everything from companies to business units. It’s like having an API key for every niche resource type in the system. If you're tracking employee status, you can also use `list_workers` and filter by specific criteria using its search parameter.

Setup guide

Set up Workday MCP in Google ADK

Prerequisites

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

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Workday tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Workday_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Workday tools via MCP.",
    tools=mcp_tools,
)
