Type-safe hotel and flight search with Pydantic AI

The `search_regions` tool returns structured region IDs, names, and coordinates to your MCP client. Pydantic AI validates this incoming geographic data against strict Python schemas before your code processes it. If the server returns an unexpected data type, the framework raises a validation error immediately. This validation extends to `search_properties` and `search_flights`. Your agent cannot pass malformed region IDs or date strings to the API because the Pydantic models block invalid inputs at the boundary. This structure guarantees that your search queries are clean.

Validate live Expedia quotes before booking

The `get_room_quotes` tool fetches live room rates and availability details. Pydantic AI parses this complex pricing JSON into structured Python objects, ensuring that currency codes and numeric rates match your expected schemas. You avoid runtime errors caused by missing fields or unexpected null values. The same validation applies to `get_flight_quotes` and `get_car_quotes`. Because your agent works with validated data, it can safely compare flight options and car classes. The framework ensures that the data used for decision-making is accurate and complete.

Secure booking commits with runtime type checks

The `create_booking` tool executes lodging reservations, requiring precise guest and payment details. Pydantic AI ensures that the payload sent to this tool conforms exactly to the required API schema. This validation prevents failed booking attempts caused by formatting errors. For transportation, the agent uses `book_car` and `book_flight` to finalize reservations. If an API call fails or returns an error, the framework catches the exception safely. You can write clean error-handling code to manage issues like sold-out flights or expired quotes.

Setup guide

Set up Expedia MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "expedia-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Expedia tools.",
)

result = await agent.run("List recent Expedia transactions")
print(result.output)
