How to Use the ChartMogul MCP in LangChain

Q: How do I connect ChartMogul to LangChain?

Install the langchain-mcp-adapters package first. Then initialize a MultiServerMCPClient pointing to the Vinkius endpoint and pass the resulting tools to your ReAct agent.

Q: Can my LangChain agent create new ChartMogul customers?

Yes, write access is supported. Your agent can execute the createcustomerrecord tool when processing signups from other connected systems.

Wire ChartMogul data into LangChain

This MCP Server exposes your core SaaS metrics directly to LangChain agents. ReAct agents can grab high-level numbers via `get_summary_metrics` and immediately decide which underlying trend needs deeper investigation. You build multi-step reasoning pipelines that actually understand your revenue. An agent spots a dip in recurring revenue using `get_mrr_history`, then automatically chains a call to `get_churn_rates` to pinpoint the exact cause before generating a report.

Deep dive into customer profiles

Fetching individual account data happens through the `get_customer_details` tool. Your LangChain setup pulls the raw profile, feeds it into an LLM prompt, and extracts exact usage patterns. Agents combine these profiles with financial context. They hit `get_customer_ltv` to calculate lifetime value, allowing your custom LangGraph nodes to route high-value accounts to priority support queues automatically.

Track expansion via MCP Server

You monitor user base expansion using the `get_customer_count_history` and `get_arr_history` tools within your automated workflows. LangSmith traces every single API call, showing you exactly how many tokens your financial analysis consumes. Connecting the dots between billing tiers and active users becomes trivial. Your chain queries `list_subscription_plans` to map out pricing structures, then correlates those tiers against active subscriptions to find upsell targets.

Setup guide

Set up ChartMogul 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 ChartMogul 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({
    "chartmogul-alternative-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 ChartMogul transactions"
    })
    print(result["messages"][-1].content)

Common questions about ChartMogul MCP in LangChain

Install the `langchain-mcp-adapters` package first. Then initialize a `MultiServerMCPClient` pointing to the Vinkius endpoint and pass the resulting tools to your ReAct agent.

Yes, write access is supported. Your agent can execute the `create_customer_record` tool when processing signups from other connected systems.

Standard wrappers require hardcoding every endpoint into your chain. This MCP implementation dynamically exposes the tools, letting LangChain agents autonomously decide when to check MRR or churn rates.

Yes, they do. Every call to the ChartMogul MCP Server appears in your LangSmith traces, complete with latency metrics and the exact inputs your agent provided.

Vinkius runs the integration inside an ephemeral V8 Isolate Sandbox. Your MRR history and individual customer LTV figures never persist on our infrastructure, passing straight from the source to your LangChain environment.
