How to Use the LeafLink MCP in Google ADK

Q: How do I restrict Google ADK to only read LeafLink data?

Use the toolnames filter when initializing your toolset. This allows you to expose catalog details while completely blocking write tools like order updates.

Feed your wholesale cannabis inventory and order data directly into Gemini models using the Google ADK for enterprise automation.

Track Wholesale Orders in BigQuery

The `list_received_orders` tool pulls your entire wholesale purchase history directly into your Gemini agent context using the MCP standard. This allows your agent to compare live sales data against historical trends stored in BigQuery. Google ADK handles the heavy lifting, allowing Gemini to parse thousands of order records using its million-token context window. You get instant summaries of your wholesale pipeline without writing complex SQL queries.

Update LeafLink Inventory via MCP Server

The `update_product_inventory` tool changes stock levels for specific SKUs directly from your enterprise Python pipelines. Your agent triggers this tool when Google Cloud Pub/Sub signals a change in your physical warehouse. This MCP Server integrates with Google ADK by exposing standard HTTP tools that Gemini can invoke natively. You do not need to write custom integration code to bridge your Google Cloud infrastructure with your cannabis catalog.

Audit Buyer Activity and Brand Performance

The `list_wholesale_customers` tool retrieves active buyer profiles and licensing details from your wholesale account. Your agent uses this data to verify dispensary credentials before processing new requests. By pairing this with `list_wholesale_brands`, your Google ADK agent can map which brands are performing best across different dispensary regions. It gives your sales team actionable reports generated straight from live API data.

Setup guide

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