How to Use the Expedia Hotels MCP in LangChain

Q: How does Expedia Hotels handle price validation in my LangChain agent?

The agent calls pricecheck using the IDs retrieved from getrateplans. This ensures the price you see is the price you pay before the booking is finalized.

Q: Is it possible to chain guest reviews into my LangChain logic?

You can use getguestreviews as a node in your chain to filter hotels. The agent reads the ratings and text to decide if a property meets your quality requirements.

Perplexity

Chain together your travel research

Feed the output of `search_regions` directly into `search_hotels` to build dynamic discovery chains. Your agent handles the logic of finding valid properties before checking specific inventory. This MCP Server allows your chain to pass state between steps without manual intervention. You get full visibility into how your agent chooses which properties to investigate based on the initial search.

Validate rates with LangChain agents

Stop guessing if a price is current. Your agent uses `price_check` to verify data from `get_rate_plans` before committing to a final booking. It prevents booking errors by requiring a secondary check against the live API. Your agent confirms the total cost in the chain before it ever executes the `book_hotel` tool.

Automate itinerary management

Handle your bookings from start to finish within your LangChain workflow. Use `get_itinerary` to pull current status updates and `cancel_itinerary` if your agent decides to rebook. Everything stays tracked within your environment. You maintain full control over the booking lifecycle while the agent manages the repetitive API interactions.

Setup guide

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 Hotels 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.

Common questions about Expedia Hotels MCP in LangChain

You initialize the server and pass the tools to your agent. Use `search_regions` to find the correct ID and then pipe that into `search_hotels` to get a list of available properties.

Yes, but you should always set a human-in-the-loop step. The `cancel_itinerary` tool performs the action, but you need to verify the policy returned by `get_itinerary` first.

The agent calls `price_check` using the IDs retrieved from `get_rate_plans`. This ensures the price you see is the price you pay before the booking is finalized.

You can use `get_guest_reviews` as a node in your chain to filter hotels. The agent reads the ratings and text to decide if a property meets your quality requirements.

Your booking details like guest names and email addresses are transmitted directly to the provider. The MCP server acts as a secure bridge, and no sensitive information is cached locally.
