Perplexity

Automate Complex Redemption Workflows

You can build a sequence where the agent first finds a `get_customer` profile, then uses that data to determine which campaign is appropriate. It runs `create_voucher`, and finally simulates the claim with `redeem_voucher`. This hands-on chain handles the entire lifecycle of a discount.

Audit and Track Usage Across Clients

Need to see what happened last month? Use this client to list all activity. You can call `list_customers` for an account roster, check `list_campaigns` for active promotions, or use `list_redemptions` to track specific voucher usage.

Systematic Campaign Maintenance

Managing the catalog means more than just launching things. You can retire old programs by calling `delete_campaign`, or clean up expired codes using `delete_voucher`. These tools make sure your MCP Server keeps the system tidy.

Setup guide

Set up Vouchery.io 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 Vouchery.io 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({
    "voucheryio-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 Vouchery.io transactions"
    })
    print(result["messages"][-1].content)
