Perplexity

Automate player research with LangChain

Feed live stats directly into your reasoning chains. Use `get_nfl_player_details` to pull current metrics and pass that output into your next prompt without manual data entry. Your agent decides when to trigger these calls. It links `list_nba_players` with specific score queries to build a complete picture of a game day in real time.

Trace sports data flows

Monitor every tool call through LangSmith. You see exactly what `get_mlb_scores` returned and how your agent interpreted those numbers during the chain execution. Debugging is straightforward when you track inputs and outputs. You verify the chain logic against the raw data the MCP Server delivers.

Aggregate league data

Connect multiple sports feeds into a single pipeline. Your agent switches between `get_nfl_schedule` and `get_mlb_schedule` to compare cross-league activity. This setup keeps your logic centralized. You define the flow once and let the MCP Server handle the API communication for all three supported leagues.

Setup guide

Set up FantasyData (SportsDataIO) 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 FantasyData (SportsDataIO) 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({
    "fantasydata-sportsdataio-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 FantasyData (SportsDataIO) transactions"
    })
    print(result["messages"][-1].content)
