How to Use the EODHD Financial MCP in LangChain

Q: Can my agent get data for multiple stocks at once with EODHD Financial and LangChain?

Yes. Give your LangChain agent access to tools like getmultiprice or gethistoricaldividends. It can then construct the required comma-separated list of symbols and make a single, efficient call.

Q: What's the best way to find the right ticker symbol for the EODHD Financial server in LangChain?

Have your agent start with the searchtickers tool. It's designed to find the exact TICKER.EXCHANGE format needed for all the other tools like geteoddata.

Build financial data chains in LangChain to automate market analysis and research tasks without writing boilerplate API code.

Chain Financial Tool Calls

Let your agent find a ticker with `search_tickers`, then pass that symbol to `get_realtime_price` and `get_fundamentals` in sequence. The agent decides the next step based on the data it gets back. This isn't just a single API call. You're building a reasoning pipeline that can react to market data, like fetching dividend history with `get_historical_dividends` only if a stock's valuation from `get_fundamentals` meets your agent's criteria.

Automate Multi-Ticker Analysis with LangChain

Your agent can pull a whole list of symbols from an exchange using `get_exchange_symbols`. From there, it can loop through that list, calling `get_eod_data` for each one to build a historical dataset for backtesting. You can design chains that compare multiple stocks at once. For instance, an agent can get bulk prices with `get_multi_price` and then dig into the fundamentals of any outliers it identifies, all in one run.

Get Actionable Corporate Data

Go beyond just prices. Your agent can check for upcoming dividend payments using `get_dividends` or look back at historical payouts with `get_historical_dividends`. This MCP server also lets your agent track corporate restructuring by checking for stock splits with `get_splits` and `get_historical_splits`. This gives your agent the context it needs to interpret price movements correctly.

Setup guide

Set up EODHD Financial 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 EODHD Financial 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({
    "eodhd-financial-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 EODHD Financial transactions"
    })
    print(result["messages"][-1].content)

Common questions about EODHD Financial MCP in LangChain

Pass the tools from this MCP server to your agent constructor. The agent uses the tool descriptions to decide when to call `search_tickers` first, then pipe the output symbol into `get_realtime_price` or `get_fundamentals`.

Yes. Give your LangChain agent access to tools like `get_multi_price` or `get_historical_dividends`. It can then construct the required comma-separated list of symbols and make a single, efficient call.

Have your agent start with the `search_tickers` tool. It's designed to find the exact `TICKER.EXCHANGE` format needed for all the other tools like `get_eod_data`.

This isn't just a wrapper; it's a set of standardized tools your agent can reason about. LangChain decides which tool to use and when, giving it an autonomy that you don't get with direct, hardcoded API calls.

Vinkius handles the connection and authentication. The server only processes the public financial market data you request—tickers, prices, fundamentals—and it all happens in an ephemeral, sandboxed environment. Your API keys and client requests are isolated.
