How to Use the ChargeOver MCP in LangChain

Q: How do I connect the ChargeOver MCP Server to LangChain?

Install langchain-mcp-adapters and langgraph. Pass your endpoint URL into MultiServerMCPClient and call gettools() to bind the billing functions to your agent.

Q: How does LangChain handle large ChargeOver transaction lists?

You manage memory using client.session(). The framework keeps the transaction history in context across multiple turns, so your agent remembers previous payment failures during the conversation.

Build recurring billing pipelines in LangChain that automatically query invoices and trigger follow-ups based on transaction states.

Chain ChargeOver MCP Server calls

This MCP integration feeds recurring billing data directly into your ReAct agents. When a payment fails, your agent calls `list_billing_transactions` to find the decline reason, then immediately routes that data into a custom notification chain. You control the execution order. The agent decides whether to pull the raw ledger entries first or jump straight to `get_invoice_details` to draft a customer email. Every token spent analyzing these financial records gets logged in LangSmith for your review.

Audit subscriptions with ReAct agents

Give your LangChain agent the ability to inspect account health without writing custom API wrappers. By exposing `list_billing_subscriptions`, the model can iterate through active packages and identify churn risks based on usage patterns. Complex queries become simple multi-step reasoning tasks. If an account looks stale, the chain automatically executes `get_customer_details` to verify contact info before alerting your sales team.

Feed sales quotes into text chains

Connect your proposal generators straight to your billing system. Your agent runs `list_billing_quotes` to pull active pricing tiers, then formats those numbers into customized contract drafts. The output of the quote search becomes the input for your document builder. You skip the manual copy-paste routine and let the framework handle the data formatting.

Setup guide

Set up ChargeOver 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 ChargeOver 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({
    "chargeover-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 ChargeOver transactions"
    })
    print(result["messages"][-1].content)

Common questions about ChargeOver MCP in LangChain

Install `langchain-mcp-adapters` and `langgraph`. Pass your endpoint URL into `MultiServerMCPClient` and call `get_tools()` to bind the billing functions to your agent.

Yes. Every time your agent checks an invoice or pulls customer details, LangSmith logs the exact tool inputs, outputs, and latency. You see exactly how the model reasoned about the financial data.

You manage memory using `client.session()`. The framework keeps the transaction history in context across multiple turns, so your agent remembers previous payment failures during the conversation.

Yes, that is the core feature. Your agent can pull a customer record from this MCP server and immediately pass that ID into a CRM tool within the same execution chain.

Vinkius runs this connector inside a V8 Isolate Sandbox. Your raw invoice amounts, customer names, and subscription tiers never leak across sessions. The environment spins up for the query and dies immediately after returning the JSON payload.
