Perplexity

Automated market research chains

Feed `get_city_investment_performance` output directly into your next agent step to filter markets before you spend tokens on property data. Your pipeline handles the logic of narrowing down regions. Once the agent identifies a target, it invokes `get_top_neighborhoods` to refine the search. You build automated workflows where the results of one query dictate the parameters for the next without manual intervention.

Programmatic property deep dives

Trigger `get_full_property_profile` within your ReAct loops to pull granular data on specific listings. You control the sequence of data gathering to ensure your agent acts on precise, up-to-date information. Use `get_property_comps` to provide the agent with local context during its decision process. By linking these tools, you create a chain that evaluates a property against its neighbors in real time.

Investment metrics at scale

Pass data from `rento_calculator_lookup` into your LangSmith traces to monitor how your agent calculates returns. You see exactly what the model sees during every stage of the execution. This MCP server provides raw numbers that your chains interpret for risk assessment. You define the thresholds, and the agent executes the search across the available datasets.

Setup guide

Set up Mashvisor Alternative 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 Mashvisor Alternative 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({
    "mashvisor-alternative-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 Mashvisor Alternative transactions"
    })
    print(result["messages"][-1].content)

Common questions about Mashvisor Alternative MCP in LangChain

It integrates directly as a toolset within your LangGraph pipelines. You get structured output from every tool call, allowing your agents to make decisions based on real-time market data.

Yes, it returns specific JSON results that your agent parses immediately. You avoid the bloat of unnecessary text by fetching only the data points you need for your specific chain.

It relies on standard stdio or HTTP communication to ensure consistent connectivity. Your agents receive typed responses that follow the Zod schemas defined for every tool.

You define which tools the agent can access during the initial configuration. This limits the scope of what the server can execute on your behalf.

Your queries involve property addresses and financial metrics that never leave your local environment unless you explicitly send them to an external model. The server itself acts as a gateway for fetching public real estate data.
