Connect Intrinio tools to LangChain ReAct agents

Stop writing custom API wrappers for market data. This MCP Server lets your agent decide when to query financials or pull historical prices during a run. The agent grabs the output from `list_companies` and feeds it directly into `get_financials` without manual glue code. You get a clean interface where tools like `get_stock_prices` act as native steps in your agentic loop. LangChain handles the execution sequence while this MCP Server handles the actual data fetching.

Trace financial data flow with LangSmith

Every call to `get_earnings_releases` or `get_security` is fully visible in your LangSmith dashboard. You can watch the raw payload come back from Intrinio and see exactly how your agent parses the numbers. This setup makes debugging simple. When a query to `list_news` fails or returns unexpected results, you see the exact token usage and latency in your trace logs immediately.

Build composable market research chains

Link multiple steps together to automate complex valuation workflows. Your agent can run a search with `search_companies`, verify the ticker with `get_company`, and pull the IPO dates using `get_ipo_calendar` in a single execution path. Because this MCP Server integrates with the wider LangChain ecosystem, you can easily combine these financial tools with your existing SQL databases or vector stores.

Setup guide

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

Common questions about Intrinio MCP in LangChain

Install the adapter package first using pip. Then import the client, pass your Vinkius connection URL, and fetch the tools to register them with your agent.

Yes, that is how the framework shines. The output of a tool like `get_security` flows directly into the next chain link, allowing your agent to run subsequent financial queries dynamically.

The server interacts directly with the Intrinio API, meaning you need to manage rate limits through your API plan. You can write custom LangChain runnables to throttle calls to endpoints like `get_stock_prices` if needed.

Absolutely. You can register these financial tools alongside web search or database tools, giving your agent a broader context when analyzing market trends.

Your data stays inside the Vinkius sandbox during execution. This server only handles financial market data like stock prices and corporate profiles, passing them directly to your local LangChain runtime without storing them on external servers.
