How to Use the Amadeus Alternative MCP in Pydantic AI

Q: How does the Amadeus Alternative server work with Pydantic AI's validation?

When your agent calls a tool like searchflights, Pydantic AI takes the JSON response from this MCP server and parses it into a Pydantic model. If any data is missing or has the wrong type, it raises an error immediately.

Build type-safe travel agents with Pydantic AI that won't fail silently on bad API data.

Get Validated Travel Data, Every Time

This server gives your agent ten tools for travel planning, from `search_cities` to `get_seat_map`. The key is that Pydantic AI validates every response against your models. If a flight search returns a malformed price or a hotel search is missing a field, your agent will raise a `ValidationError`. You get predictable, type-safe objects to work with, not messy dictionaries.

Model-Agnostic Flight and Hotel Search

Use these travel tools with any LLM you want—OpenAI, Anthropic, Gemini, or a local model. Pydantic AI handles the tool-calling logic, so you're not locked into one provider. Your agent can find the cheapest flight dates with `get_flight_dates` or get hotel offers using `get_hotel_offers`. The logic is the same regardless of the underlying model you choose for reasoning.

A Simple MCP Toolset for Pydantic AI

Adding this MCP server is one line of code. Just create an `MCPToolset` with the Vinkius URL and add it to your agent. There's no need to define each of the ten tools by hand. This approach keeps your agent code clean. It focuses on what to do with the travel data, while the MCP toolset handles the API calls and validation for you.

Setup guide

Set up Amadeus Alternative 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": {
        "amadeus-alternative-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Amadeus Alternative MCP in Pydantic AI

When your agent calls a tool like `search_flights`, Pydantic AI takes the JSON response from this MCP server and parses it into a Pydantic model. If any data is missing or has the wrong type, it raises an error immediately.

Your Pydantic AI agent will fail loudly with a validation error instead of processing bad data. This protects your application from silent data corruption if the `search_flights` tool returns an unexpected structure.

Yes. Pydantic AI is model-agnostic. You can configure it to use a local model for reasoning while it calls the Amadeus Alternative MCP server for its travel data tools.

It's a perfect fit. The server provides discrete, structured data functions that pair well with Pydantic's validation-first approach. You build agents that are less likely to break in production.

The agent sends only the parameters for the tool it's calling, such as airport codes for `get_direct_destinations` or a city code for `search_hotels`. All requests are handled in a secure, ephemeral Vinkius sandbox that doesn't log your query data.
