How to Use the Payfunnels MCP in Google ADK

Q: How do I connect Payfunnels to Google ADK?

Use McpToolset with the StreamableHttpServerParameters pointing to your Vinkius endpoint. Pass this toolset into your Google ADK LlmAgent to instantly expose MCP tools like listsubscriptions to Gemini.

Q: Does the Payfunnels integration with Google ADK support Gemini's long context?

Yes, you can feed large outputs from listpayments directly into Gemini via Google ADK. The model processes thousands of subscription records at once to find patterns that standard dashboards miss.

Run enterprise billing actions in Gemini using Google ADK connected to your Payfunnels data.

Perplexity

Long-context billing analysis with Gemini

Pull massive transaction histories into Gemini's million-token context window using `list_payments`. Your Google ADK agent parses months of raw billing records to detect purchasing trends without running out of memory. Combine this transaction data with customer records in BigQuery to generate personalized checkout links via `create_one_time_payment_link`. The agent acts as an automated account manager that knows exactly what each customer spent.

Enterprise subscription control via Google ADK

Manage high-value accounts by connecting this MCP Server to Vertex AI pipelines. Your agent monitors recurring billing health with `list_subscriptions` and flags accounts that require manual outreach. When an enterprise customer needs a custom setup, the agent calls `create_setup_fee` directly from the Google ADK runtime. This eliminates manual billing configuration, keeping your sales pipeline moving in real-time.

Automated refund processing pipelines

Resolve charge disputes quickly by deploying support agents on Google Cloud infrastructure. The agent calls `get_payment_details` to verify the transaction history before deciding to issue a refund. If the dispute meets your criteria, the Google ADK agent triggers `refund_payment` to settle the balance. This entire loop runs inside your secure VPC, keeping sensitive financial actions isolated from public networks.

Setup guide

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

Use `McpToolset` with the `StreamableHttpServerParameters` pointing to your Vinkius endpoint. Pass this toolset into your Google ADK `LlmAgent` to instantly expose MCP tools like `list_subscriptions` to Gemini.

Absolutely. You can write a workflow where Gemini analyzes customer churn in BigQuery and uses the Google ADK to trigger `cancel_subscription` for inactive users.

Yes, you can feed large outputs from `list_payments` directly into Gemini via Google ADK. The model processes thousands of subscription records at once to find patterns that standard dashboards miss.

This integration supports both Stdio and HTTP transport layers. For enterprise deployments, we recommend using the HTTP transport with Google ADK to keep your server runtimes decoupled.

No, customer checkout links, subscription fees, and payment IDs are processed ephemerally. Vinkius secures the MCP connection with zero-trust architecture, ensuring no sensitive billing data persists in Google's model training sets.
