How to Use the American Airlines MCP in Pydantic AI

Q: What happens if the American Airlines MCP server returns bad data to Pydantic AI?

Pydantic AI will raise a ValidationError on the spot. Your agent won't silently fail or proceed with incorrect data. This protects your application from unexpected API changes or bad responses.

Q: How do I add the American Airlines tools to my Pydantic AI agent?

First, pip install "pydantic-ai-slimmcp". Then, create an MCPToolset with your Vinkius server URL and pass it into the toolsets list when you initialize your agent. That's it.

Get type-safe American Airlines flight data in your Python app with Pydantic AI. No more corrupted data or silent API failures.

Perplexity

Get Validated Flight Schedules

The `get_flight_schedule` tool fetches American Airlines flight options between two cities. Your agent gets departure times, arrival times, and aircraft info. Here’s the key: Pydantic AI validates the server's response against a Pydantic model at runtime. If the API ever returns an unexpected field or a malformed date, your code will raise a `ValidationError` immediately, so you never process bad data.

Track Flights with Guaranteed Correctness

Use the `get_flight_status` tool to get live updates for any American Airlines flight. Your agent passes a flight number and date, and gets back the current status, gate, and timing. With Pydantic AI, you're not just hoping the data is right—you're guaranteeing it. Every response from this MCP server is checked. You'll know instantly if a flight status is missing or if a time isn't in the right format, preventing bugs downstream.

Type-Safe Airport Information with Pydantic AI

The `get_airport_info` tool gives your agent structured data about airport terminals and amenities. It's perfect for building a reliable travel assistant. Because Pydantic AI is model-agnostic, you can swap between OpenAI, Anthropic, or a local LLM without changing your tool code. The validation layer ensures that no matter which model is driving the agent, the data it gets from the American Airlines MCP tools is always correct.

Setup guide

Set up American Airlines 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": {
        "american-airlines-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about American Airlines MCP in Pydantic AI

Pydantic AI will raise a `ValidationError` on the spot. Your agent won't silently fail or proceed with incorrect data. This protects your application from unexpected API changes or bad responses.

Yes, that's one of its biggest strengths. You can use this MCP server with an agent powered by OpenAI, Gemini, or any other supported model. The Pydantic AI toolset works the same way across all of them.

First, `pip install "pydantic-ai-slim[mcp]"`. Then, create an `MCPToolset` with your Vinkius server URL and pass it into the `toolsets` list when you initialize your agent. That's it.

Yes. Pydantic AI handles the interaction with the MCP server, gets the JSON response, and parses it into a corresponding Pydantic model for you. You get a clean, typed Python object to work with.

The server only sees the data required for the query, like airport codes and travel dates. This information is handled within a dedicated, short-lived Vinkius environment for each request and is not stored or logged.
