Enterprise Invoice Auditing at Scale

By calling `list_invoices`, your Gemini agent can feed your sales data directly into BigQuery. It matches completed transactions against your actual bank records in real time. Gemini uses its massive context window to process thousands of billing lines at once. The agent detects unpaid balances by cross-referencing `list_estimates` with active invoice series pulled from `list_sequences`.

Automated Client Sync via Google ADK

Using `create_client`, your Gemini agent keeps your cloud database and billing software aligned. When a new contract closes, the agent registers the business, falling back to consumer status if no NIF is supplied. The agent then runs `list_taxes` to find the correct Portuguese VAT rate and executes `create_item` to log the billable service. This ensures your catalog is always ready for immediate, compliant invoicing.

Instant Shipping and Transport Logging

By calling `list_guides`, your Gemini agent can manage physical logistics directly. It monitors active transport documents and verifies that goods are moving legally under Portuguese transport rules. This MCP Server lets your agent inspect logistics data and link it to customer accounts. The agent queries `get_client` to verify shipping addresses before any transport guides are generated.

Setup guide

Set up InvoiceXpress (Online Invoicing) 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 InvoiceXpress (Online Invoicing) 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="InvoiceXpress (Online Invoicing)_agent",
    model="gemini-2.0-flash",
    instruction="You have access to InvoiceXpress (Online Invoicing) tools via MCP.",
    tools=mcp_tools,
