Perplexity

Sequence complex billing logic

Connect `list_catalog_products` to `list_product_price_tags` to build reasoning chains that validate pricing tiers before any quote reaches a customer. You create a pipeline where the agent evaluates specific product metadata as the first link in your chain. The output of these calls feeds directly into your logic. Your agent decides the next step, ensuring your revenue models stay tight and error-free.

Automate revenue workflow triggers

Trigger `list_revenue_workflows` based on state changes captured in your chain. Your agent monitors these workflows to ensure every transaction aligns with your internal compliance rules without manual intervention. This removes the need for constant human oversight. The agent handles the data flow, keeping your financial operations moving in sync with your LangChain agent's execution.

Trace every pricing decision

Use LangSmith to log every tool call, from `list_product_bundles` to the final output. You see exactly what the agent saw when it made a decision, providing a clear audit trail for your pricing strategy. Observability is built-in. You stop guessing why a price was generated and start seeing the raw data that drove the calculation.

Setup guide

Set up Nue.io Revenue 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 Nue.io Revenue 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({
    "nueio-revenue-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 Nue.io Revenue transactions"
    })
    print(result["messages"][-1].content)
