Chain Appfigures data in LangChain

Feed `get_revenue_report` and `get_sales_report` results directly into your LLM chains. Your agent processes these figures to generate summaries or trigger downstream logic based on real-time download and return counts. Chain complex logic by passing `get_ranks` output into a vector store. LangChain handles the transition between the Appfigures MCP server and your other data sources without extra glue code.

Monitor app performance with LangChain

Trigger `list_reviews` to pull user feedback into your pipeline. Your agent identifies sentiment shifts or common bugs before they escalate into support tickets. Automate your tracking by using `list_featured` within a scheduled run. LangChain logs the output, giving you a clear audit trail of when your product hits the store front page.

Handle Appfigures account state

Verify your setup using `get_account_check` before your agent starts its work. This prevents silent failures when your LangChain pipeline relies on specific store IDs. Fetch your list of products using `list_my_products` to scope your agent's focus. You control exactly which apps get analyzed by filtering the results returned by this MCP server.

Setup guide

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