How to Use the Bridge Data Output MCP in LangChain

Q: Can LangChain use Bridge Data Output to filter listings by price?

Yes, your agent can call searchpropertiesbyprice to find properties matching specific budgets. The agent handles this tool call during its reasoning loop and passes the filtered list to the next chain step.

Feed live MLS listings directly into your LangChain chains to build automated real estate workflows.

Pull live MLS property data into your LangChain runs.

This MCP Server exposes real estate tools like `list_properties` and `get_property` to feed live MLS listings directly into your LangChain agents. You get raw, standardized data fields without scraping or cleaning messy HTML. LangChain chains pass these property payloads directly to downstream steps. Your agent can pull a listing with `get_property`, extract the key details, and immediately format a client email in a single run.

Search properties by city and price dynamically.

The `search_properties_by_city` and `search_properties_by_price` tools let your agent filter the market based on client budgets and locations. It runs these lookups as active steps in your decision chains. Instead of hardcoding search parameters, your agent reads user emails, extracts the target city, and calls the search tools. LangSmith traces the exact inputs and outputs so you can audit the tool calls.

Retrieve agent details and media assets.

The `list_members`, `list_offices`, and `list_media` tools pull real estate agent directories and listing photos straight into your workflows. This gives your agent the context needed to match listings with listing agents. You can chain these tools to build automated broker reports. Your agent finds a listing, gets the media files, grabs the listing agent's office info, and compiles a clean PDF package.

Setup guide

Set up Bridge Data Output 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 Bridge Data Output 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({
    "bridge-data-output-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 Bridge Data Output transactions"
    })
    print(result["messages"][-1].content)
