How to Use the Lago MCP in Google ADK

Q: Can a Google ADK agent manage customer wallets in Lago?

Yes, the agent uses createwallet to provision prepaid balances. It can also query those balances to alert customers when they run low on credits.

Connect Lago to your Google ADK agents to process usage events and manage billing directly from your Gemini workflows.

Perplexity

Enterprise Event Ingestion from BigQuery

The `batch_events` tool transmits large volumes of usage data from your Google Cloud infrastructure to Lago using our MCP server. Your Gemini agent queries BigQuery, formats the raw usage rows, and passes them directly to this ingestion tool. For real-time updates, the agent uses `send_event` to push individual actions as they happen. This architecture handles high-throughput pipelines without requiring intermediate middleware.

Context-Aware Subscription Management via MCP Server

The `get_subscription` tool retrieves active plan details to feed into Gemini's 1M+ token context window. This allows your Google ADK agent to analyze a customer's entire billing history and usage patterns in a single reasoning step. When the agent detects an upsell opportunity, it executes `create_subscription` to transition the customer to a higher tier. You control which tools are exposed by configuring the toolset filter during initialization.

Automated Ledger and Wallet Operations

The `create_wallet` tool sets up prepaid credit balances for your enterprise clients. Your agent monitors these balances and triggers top-ups by calling the tool when credits fall below a defined threshold. To resolve billing disputes, the agent calls `list_invoices` to pull historical payment records. It compares these records against your internal cloud logs to verify billing accuracy.

Setup guide

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