Discover Campaigns and Status

You can start by finding what's available. Call `list_campaigns` to see every referral campaign ID you have set up. Once you know the ID, use `get_campaign` for the full details, or run `get_campaign_stats` to pull performance metrics. This lets your agent build a report that tracks both raw numbers and specific goals.

Managing Participants via MCP Server

The chain handles participant lifecycle management. First, use `get_participant` with an email address to get their current record. Then, if you need them to share their link, the agent calls `get_referral_url`. This sequence of tool calls lets your pipeline build a profile on the user's status.

Milestone and Reward Logic

Building complex reward logic is easy. Your chain can query milestones using `get_milestones` to see if a participant hit their discount or free product goal. It also fetches the exact rules via `get_rewards`. This lets your agent make decisions based on documented campaign rules.

Setup guide

Set up Viral Loops MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Viral Loops tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "viral-loops-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent Viral Loops transactions"
    })
    print(result["messages"][-1].content)
