Identifying Accounts with the MCP Server

Start by calling `list_organizations` to get all organization IDs. This is necessary because most other tools need a valid scope identifier before they can run. Once you have the ID, your agent passes it along, ensuring every subsequent action targets the correct billing entity in Zoho Invoice.

Creating Invoices using Google ADK

When it's time to bill a customer, use `create_new_invoice`. You structure the necessary JSON body—including line items and totals—and send it through your agent. This function writes the new invoice record directly into Zoho Invoice.

Retrieving Comprehensive Records with Google ADK

Need an overview of all outstanding bills? Call `list_invoices` to retrieve a full list. This pulls data on every billable transaction in the organization. Furthermore, you can get granular product info using `list_invoice_items`, ensuring your agent has access to your entire service catalog.

Setup guide

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