Perplexity

Automated rental discovery for LangChain

Chain `search_rental_regions` and `search_rentals` to turn vague destination requests into hard availability data. You define the logic, and your agent handles the sequence of calls to identify properties that match your specific criteria. Stop digging through static pages. By linking these tools, your agent filters results based on your requirements, ensuring you only spend time evaluating properties that are actually available for your dates.

Deep property evaluation pipelines

Use `get_rental_details` and `get_unit_amenities` as intermediate steps in your LangChain pipeline to build a comprehensive profile of any listing. Your agent gathers the specs and formats them into a summary before you ever touch a browser. This approach removes guesswork. You can force the agent to check `get_rental_reviews` for every candidate, ensuring that only high-rated properties make it to the final stage of your reasoning chain.

Policy-aware booking automation

Integrate `check_rental_policies` into your workflow to ensure your agent understands the fine print before executing `book_rental`. This adds a mandatory validation step that prevents accidental commitments to non-refundable properties. Your agent checks the rules, validates the itinerary, and prepares the booking for your final sign-off. It keeps you informed of all obligations, keeping the process transparent and under your control.

Setup guide

Set up Expedia Vrbo 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 Expedia Vrbo 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({
    "expedia-vrbo-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 Expedia Vrbo transactions"
    })
    print(result["messages"][-1].content)
