How to Use the ReferralHero MCP in Google ADK

Q: How do I configure ReferralHero tools inside Google ADK?

Instantiate McpToolset with your Vinkius HTTP transport URL and pass it to your Google ADK LlmAgent tools array. Your Google ADK agent will immediately discover the ReferralHero tools and make them available to Gemini.

Q: Can I restrict which ReferralHero tools my Google ADK agent can access?

Yes, you can pass a toolnames filter to your Google ADK StreamableHttpServerParameters to expose only specific tools like getsubscriber. This prevents your agent from calling destructive tools like deletesubscriber in your ReferralHero campaign.

Q: How does Google ADK handle long-context ReferralHero analysis?

The Google ADK framework feeds raw JSON from listtransactions directly into Gemini's context window. This allows the agent to analyze months of ReferralHero transaction history in a single pass without pagination bottlenecks.

Run enterprise referral loops by hooking ReferralHero tools directly into Google ADK pipelines for long-context Gemini agents.

Sync BigQuery Data to ReferralHero via Google ADK

`list_subscribers` fetches your active ReferralHero campaign participants so your Google ADK agent can cross-reference them with BigQuery tables. The Gemini agent processes millions of tokens of customer data to identify top-performing cohorts. Once identified, the Google ADK agent uses `update_subscriber` to write custom attributes back to ReferralHero. This keeps your marketing campaigns aligned with your core Google Cloud data warehouse without manual ETL pipelines.

Automate Reward Distribution with Google ADK

`get_rewards` retrieves active ReferralHero campaign incentives so your Google ADK agent can match them against customer action logs. The agent maps complex referral structures directly within Gemini's massive context window. When a referral triggers, the Google ADK agent runs `track_conversion` to log the event. This updates the ReferralHero ledger and triggers downstream Google Cloud tasks to fulfill the reward.

Monitor Campaign Performance with MCP Server Tools

`list_lists` displays all your active ReferralHero programs to give your Google ADK agent a high-level view of your marketing setup. The agent uses this list to run automated performance audits across different campaigns. To dive deeper, the Google ADK agent calls `get_leaderboard` to extract individual performance metrics. This MCP Server connection lets your Gemini models analyze viral coefficients and output reports directly to Google Cloud Storage.

Setup guide

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