Perplexity

Run enterprise billing pipelines in Google ADK

Enterprise billing requires processing massive amounts of data. Using Gemini's million-token context window, your Google ADK agent can analyze thousands of lines of raw usage logs and prepare Invoice Ninja records. The Google ADK agent uses `create_invoice` and `create_product` to write these charges directly to your account. You get clean, automated billing that scales with your Google Cloud infrastructure without manual intervention.

Sync BigQuery datasets with Invoice Ninja

Keep your cloud data warehouse and your billing platform in lockstep. Your Google ADK agent can call `list_clients` and `list_payments` to pull billing statuses, then cross-reference them with your internal BigQuery tables. If the Google ADK agent detects a missing record, it runs `create_client` to fix the mismatch. This prevents data drift between your core business systems and your Invoice Ninja setup.

Use this MCP Server to automate payment audits

Auditing transactions shouldn't take hours of manual checking. Your Google ADK agent can pull details using `get_payment` and `get_invoice` to reconcile bank deposits against outstanding accounts receivable. Because this MCP Server integrates directly into the Google ADK LlmAgent constructor, you can build autonomous workflows that flag unpaid bills. It turns a tedious finance chore into a background process that runs on Google Cloud.

Setup guide

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