How to Use the Expedia Car Rental MCP in Google ADK

Q: Can I filter Expedia Car Rental results using my Google ADK agent?

The searchcars tool accepts optional parameters for vehicle class, supplier, and price. Your agent passes these filters to narrow down the results based on user preferences.

Connect your Google ADK agent to the Expedia Car Rental MCP Server for automated booking and regional search.

Perplexity

Discover rental regions via Google ADK

Your agent uses `search_car_regions` to resolve city names into valid location identifiers. This is the first step in any workflow that requires precise pickup data. After getting the region, the agent executes `get_pickup_locations` to find specific counters. This allows your Google ADK agent to provide granular options to the user.

Manage bookings with enterprise precision

The `book_car` tool creates your reservation using the offer ID provided by the search results. Your agent handles the confirmation and stores the itinerary ID for future use. If a booking needs adjustment, the agent calls `cancel_itinerary`. This process respects the specific cancellation policies tied to the vehicle provider.

Retrieve vehicle media and specs

Your agent calls `get_car_details` to present technical specifications and included amenities. This helps differentiate between vehicle classes before you commit to a booking. It uses `get_car_images` to fetch visual assets for the vehicle. These images provide a clear expectation of the car class you are reserving.

Setup guide

Set up Expedia Car Rental MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Expedia Car Rental tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Expedia Car Rental_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Expedia Car Rental tools via MCP.",
    tools=mcp_tools,
)

Common questions about Expedia Car Rental MCP in Google ADK

The McpToolset connects to the server and registers the tools with your agent. You then invoke these tools as standard functions within your agent logic.

The `search_cars` tool accepts optional parameters for vehicle class, supplier, and price. Your agent passes these filters to narrow down the results based on user preferences.

The agent receives a standard error response from the MCP server. You can catch these exceptions in your agent code to prompt the user for corrected information.

The server requires an endpoint token for all requests. The Google ADK toolset handles this authentication during the initial handshake.

The server touches only the booking confirmation and itinerary IDs. These are transmitted over an encrypted channel and never persisted on Vinkius infrastructure.
