How to Use the AfterShip Tracking MCP in Pydantic AI

Q: How do I integrate AfterShip Tracking with Pydantic AI?

Install pydantic-ai-slimmcp and use the unified MCPToolset pointing to your Vinkius HTTP URL. Pass this toolset to your Agent's toolsets parameter to expose the tracking capabilities.

Q: How does Pydantic AI handle invalid tracking data from AfterShip Tracking?

If gettrackingdetails returns unexpected data, Pydantic AI raises a validation error at runtime. This stops the agent from executing actions based on corrupted cargo details.

Type-safe shipment monitoring with Pydantic AI

The `get_tracking_details` tool on this MCP Server provides structured shipping data directly to your Python agents. When your agent calls this endpoint, Pydantic AI validates the returned status, location, and carrier fields at runtime against strict schemas. If the shipping API returns an unexpected payload format, the system raises a validation error immediately. This prevents your agent from making decisions based on malformed or hallucinated tracking data.

Validate carrier profiles before routing

The `list_couriers` tool returns the list of active shipping carriers configured in your account. Your agent uses this tool to check if a carrier is supported before attempting to register a package. By enforcing strict type checking, your code ensures that the carrier code matches expected string formats. This eliminates runtime crashes when passing carrier data to other internal APIs.

Register and verify tracking numbers safely

The `create_tracking` tool on this MCP Server registers new shipments for active monitoring. Your agent validates the input tracking number pattern using `detect_courier` first, ensuring only valid formats are sent to the API. Once registered, you can track the status by calling `list_trackings`. The returned list is structured into clean Pydantic models, making it easy to parse historical shipments in your backend code.

Setup guide

Set up AfterShip Tracking 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": {
        "aftership-tracking-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about AfterShip Tracking MCP in Pydantic AI

Install `pydantic-ai-slim[mcp]` and use the unified `MCPToolset` pointing to your Vinkius HTTP URL. Pass this toolset to your Agent's `toolsets` parameter to expose the tracking capabilities.

If `get_tracking_details` returns unexpected data, Pydantic AI raises a validation error at runtime. This stops the agent from executing actions based on corrupted cargo details.

Yes. Because Pydantic AI is model-agnostic, you can use these shipping tools with OpenAI, Anthropic, Gemini, or local models while maintaining strict type validation.

No. The server runs externally on Vinkius. Your Python code connects to the hosted endpoint via the `MCPToolset` using Streamable HTTP or SSE transports.

Every request containing tracking numbers or carrier details is routed through an ephemeral, zero-trust sandbox. No data is cached or logged on Vinkius, and transport-level encryption secures all API communication.
