Perplexity

Reasoning over revenue data

The `get_subscription_metrics` and `get_mrr_metrics` tools pull top-level revenue figures directly into your ReAct agent's context. Your LangChain agent evaluates current monthly recurring revenue against historical trends before deciding its next step. Because LangChain treats every tool output as an input for the next chain link, you can pass this MRR data straight into a forecasting prompt. LangSmith logs the exact token usage and latency for every API call made to your billing account.

Drilling into customer data with LangChain

`get_mogul_customer_details` and `list_mogul_customers` fetch specific account histories and subscription statuses. The agent requests a list of all active users, identifies those with declining spend, and isolates their records. You build a pipeline that triggers these tools sequentially. If a customer shows churn risk based on the data, the agent routes that specific profile to a retention workflow.

Verifying connections automatically

`ping_mogul_api` and `list_mogul_data_sources` verify your connection and map out where your billing data originates. Your LangChain setup runs a quick health check before executing complex analytical chains. Relying on the Vinkius managed MCP Server infrastructure means you bypass custom authentication logic. You pass a single endpoint token to the client, and the agent handles the rest.

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-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

You initialize the client and pass the URL. Call the tool fetching method and feed that array directly to your ReAct agent.

Yes, LangSmith traces every tool execution. You see exactly how long the metrics fetch takes and how many tokens the response consumes.

Your LangChain agent catches the error. You can build a fallback chain that runs a ping command to test the connection before retrying the failed request.

You can aggregate this endpoint with other data sources. The framework natively supports combining multiple MCP APIs into a single agent context.

ChartMogul holds sensitive MRR, ARR, and customer billing histories. Vinkius runs the integration inside an ephemeral V8 isolate sandbox that spins down immediately after the agent reads the metrics, leaving zero persistent footprint.
