How to Use the Alegra MCP in Google ADK

Q: How do I connect the Alegra Alternative MCP server to my Google Cloud agent?

You initialize the McpToolset using the streamable HTTP transport and your Vinkius endpoint URL. Pass this toolset directly to your LlmAgent in your Python code. Your enterprise agent can then immediately call all 14 accounting tools on the MCP.

Q: Does this integration support real-time tax rate lookups?

Yes, the agent uses listtaxes to fetch current tax configurations. It applies these rates dynamically when generating invoices or bills, avoiding manual calculation errors.

Q: How is my company's invoice and bank account data protected?

Your financial records, including bank balances from listbankaccounts and invoice details, transit through secure, ephemeral V8 isolates. Vinkius hosts this MCP server with zero retention, meaning your corporate ledger remains private.

Connect your enterprise Gemini models to Colombian accounting using the Google ADK to automate invoicing and inventory.

Match BigQuery records to Colombian tax contacts

The `create_contact` tool registers new clients and suppliers in your accounting system using NIT, CC, or CE identification. When integrated with Google ADK, your Gemini agent reads raw customer data directly from BigQuery tables. It instantly formats this data to match Colombian tax standards before executing the registration. Vertex AI models process these large data dumps without breaking a sweat, thanks to their massive context windows. The agent cross-references existing profiles using `list_contacts` to prevent duplicate entries. This keeps your customer database clean and compliant.

Run high-volume billing via Google ADK MCP Server

The `create_invoice` tool processes sales invoices and handles DIAN electronic stamping in one step. Your Google ADK agent pulls transactional data from your enterprise database and runs the invoice creation automatically. You don't have to copy-paste line items or manually verify tax rates. To ensure accuracy, the agent calls `list_taxes` to apply the correct rates to each invoice line. This end-to-end automation keeps your sales pipeline moving fast. No human intervention is needed to process daily transaction batches.

Track multi-warehouse inventory and bills

The `list_warehouses` tool lists all physical storage locations configured in your accounting platform. Your Google ADK agent queries this list to track where specific goods are stored. When stock levels drop, the agent coordinates with your supply chain data to reorder items. To manage these incoming costs, the agent uses `list_bills` to track outstanding supplier invoices. It updates your inventory records using `create_item` as soon as new shipments arrive. This keeps your balance sheet and warehouse counts aligned.

Setup guide

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

Common questions about Alegra MCP in Google ADK

Gemini's million-token context allows the agent to analyze thousands of lines of raw transaction data at once. The agent then calls `list_invoices` or `list_payments` to reconcile your books in a single run. This makes large-scale financial auditing incredibly fast.

Yes, the Google ADK allows you to pass a specific list of tool names to the toolset configuration. If you want to block your agent from creating invoices, simply exclude `create_invoice` from the initialization parameters. This keeps your financial actions strictly controlled.

You initialize the `McpToolset` using the streamable HTTP transport and your Vinkius endpoint URL. Pass this toolset directly to your `LlmAgent` in your Python code. Your enterprise agent can then immediately call all 14 accounting tools on the MCP.

Yes, the agent uses `list_taxes` to fetch current tax configurations. It applies these rates dynamically when generating invoices or bills, avoiding manual calculation errors.

Your financial records, including bank balances from `list_bank_accounts` and invoice details, transit through secure, ephemeral V8 isolates. Vinkius hosts this MCP server with zero retention, meaning your corporate ledger remains private.
