How to Use the Billsby MCP in Google ADK

Q: How do I initialize the Billsby toolset inside my Google ADK project?

Install the ADK package, then instantiate McpToolset using the Streamable HTTP server parameters pointing to your Vinkius URL. Pass this toolset object directly into your LlmAgent tools array to expose all ten billing tools to Gemini.

Q: Can I restrict Google ADK to only read Billsby data?

Yes, you can pass a list of allowed tool names to your McpToolset configuration. If you only want to read data, restrict the tools to getsubscription, listinvoices, and listplans, blocking write operations like createcustomer.

Q: Can my agent generate invoices directly?

The server lets you inspect past billing history using listinvoices. While it does not generate new PDF files, your agent can extract invoice details and format them for your customers in plain text or markdown.

Analyze subscription trends with Gemini long-context

The Billsby MCP Server feeds raw subscription data directly into Gemini's massive 1M+ token context window. Your agent pulls entire customer histories using `list_subscriptions` and `list_customers` without running out of memory. This allows for deep, historical analysis of your churn patterns. Instead of running complex SQL queries, you ask your agent to find patterns in your customer billing profiles. The model processes the full dataset in seconds, pointing out which plans are driving the most revenue.

Sync Google ADK agents with your billing database

This MCP Server links your Vertex AI models directly to live customer billing records. Your agents call `get_customer` to verify account status before executing automated customer service tasks. This keeps your Google Cloud infrastructure in sync with your actual revenue. You can combine this toolset with BigQuery data to build predictive models. The agent checks `get_customer_subscriptions` and cross-references it with usage logs to flag accounts that are likely to cancel.

Manage product catalogs from your enterprise terminal

The Billsby MCP Server allows Gemini models to inspect your pricing models using `list_plans` and `list_products`. Your agents can instantly check which add-ons are active by calling `list_addons`. This eliminates the need to build custom dashboard interfaces for internal teams. When pricing updates occur, your agent compares the live catalog against your documentation. It flags discrepancies automatically, keeping your sales team aligned with actual pricing tiers.

Setup guide

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