How to Use the Hostfully MCP in LangChain

Q: How do I connect the Hostfully MCP Server to LangChain?

Install the langchain-mcp-adapters package. Initialize the client with your Hostfully endpoint URL and register the tools directly into your agent's tool list.

Q: Can LangChain agents update Hostfully leads in real-time?

Yes. The agent uses listleads to fetch active bookings and getlead to inspect specific details, feeding that data directly into your decision chains.

Q: How does LangSmith help debug Hostfully tools in LangChain?

LangSmith traces every call to listproperties or listguests. You see the raw inputs, API response times, and exact token costs for every property management step.

LangChain agents now run your Hostfully vacation rentals by chaining property, lead, and guest data directly into multi-step runs.

Perplexity

Chain property lookups directly to guest communication

LangChain chains together your Hostfully listings and guest queries without manual scripting. When a guest asks about a specific house, your agent uses `list_properties` to pull current listings, feeds the output to the next step, and runs `get_property` to grab the exact check-in details. You do not write glue code to pass variables between these steps. The output of the property lookup feeds the prompt template for the next chain link automatically, letting your agent draft personalized replies based on real-time rental data.

Trace reservation lead pipelines in LangSmith

Stop guessing why your booking agent failed to close a lead. By exposing `list_leads` and `get_lead` as tools to your LangChain agent, every decision, tool call, and token count gets logged in LangSmith so you can debug latency issues instantly. If an agent fails to match a lead with an owner using `list_owners`, you will see the exact JSON payload that broke the chain. This visibility keeps your vacation rental pipeline running without silent failures or dropped bookings.

Run multi-step property operations

Run complex workflows that span multiple Hostfully endpoints in a single execution. Your agent uses `list_webhooks` to monitor incoming booking events, then immediately triggers `list_service_providers` to assign cleaners to the newly booked property. This MCP setup allows your LangChain run to dynamically decide which service provider to contact based on the agency details retrieved via `get_agency`. You get a self-correcting operations flow that adapts as your reservation data changes.

Setup guide

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