Type-safe FedEx address validation

The `validate_address` tool returns data that Pydantic AI checks against your schema. If the API returns junk, the agent stops immediately. This prevents bad addresses from entering your shipping system. You get clean, validated data every time the agent runs.

Get accurate FedEx rates

Your agent uses `get_rates` to fetch pricing for specific service types. Pydantic models force the agent to handle the currency and date formats correctly. This eliminates hallucinated shipping costs. Every rate returned matches the expected data structure defined in your code.

Verify FedEx service status

The `check_service_availability` tool tells the agent which services are running. It validates the service name against your internal logic. Your agent avoids booking restricted services. It ensures every shipment uses an available, valid option.

Setup guide

Set up FedEx 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": {

)

result = await agent.run("List recent FedEx transactions")
