How to Use the Wherefour MCP in Google ADK

Q: How do I use Wherefour with Google ADK?

You initialize the toolset using McpToolset and pass it as a tool list to your LlmAgent. Since you're on Cloud infrastructure, this integrates nicely with BigQuery for deeper data analysis.

Q: What kind of operational tools does Wherefour offer with Google ADK?

It covers the full supply chain: listing vendors (listvendors), checking purchase records (listpurchases), and managing sales orders (listorders). You can build agents that handle everything from sourcing to shipping.

Q: Can I get a list of all inventory items using Wherefour with Google ADK?

Yes, the listinventoryitems tool pulls every item name and SKU. You can then pass that data into BigQuery for complex joins or aggregations within your agent's workflow.

Perplexity

See all product formulas and recipes

Need to know how a finished good is made? The `list_formulas` tool lists every production recipe available in the system. This lets your agent understand Bill of Materials (BOM) requirements. If you need details on one specific item, use `get_inventory_item`. You can trace that single product back through its component parts and check against existing formulas.

Audit sales history by client

The agent pulls up a customer's entire buying record using `list_invoices` and `get_order`. This gives you both the total financial picture and the specific products they bought. Furthermore, running `list_customers` ensures that even if an account is dormant, its basic data remains available for your agent to reference.

Manage stock lots and locations

Tracking physical goods requires knowing where they are. The `list_locations` tool shows every storage area you have on site. Pair that with `list_stock_lots` to see the specific batches of product in those areas. This combination is critical for traceability, letting your agent pinpoint exactly which lot number needs to be shipped or investigated.

Setup guide

Set up Wherefour 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 Wherefour 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="Wherefour_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Wherefour tools via MCP.",
    tools=mcp_tools,
)
