Type-Safe Package Tracking with Pydantic AI

`track_package` retrieves real-time shipment status with strict runtime validation. Pydantic AI guarantees that every checkpoint, timestamp, and location string matches your expected schema before your agent acts on it. If the carrier is unknown, `identify_carrier` resolves the tracking number to the correct provider. The validated output prevents silent errors, ensuring your agent never sends bad payloads to downstream services. This MCP toolset keeps your pipeline clean.

Validated Waybill Dispatch and Pricing

`submit_shipping_order` generates electronic waybills with complete schema validation. This tool ensures that address fields, weights, and carrier codes conform to strict types before submission. To prevent booking errors, `query_shipping_price` checks shipping rates dynamically. Your agent compares these rates with `check_carrier_availability` to confirm routing and pricing before generating labels.

Map Routing and Webhook Subscriptions

`get_map_tracking` returns structured coordinate data for rendering package routes. Your agent parses these coordinates safely, avoiding malformed location strings during high-volume tracking runs. For push-based updates, `subscribe_tracking` establishes webhook connections. This tool registers your callback endpoint, triggering structured tracking updates whenever the shipment status changes.

Setup guide

Set up KuaiDi100 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": {
        "kuaidi100-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to KuaiDi100 tools.",
)

result = await agent.run("List recent KuaiDi100 transactions")
print(result.output)

Common questions about KuaiDi100 MCP in Pydantic AI

Initialize the `MCPToolset` with your server's HTTP endpoint. Pass this toolset instance inside the `toolsets` list when defining your Pydantic AI agent.

The framework intercepts the tool response and validates it against internal schemas. If the API returns unexpected date formats, Pydantic AI raises a validation error immediately.

You must pass the tracking number and the recipient's phone number to `track_package`. The tool validation schema ensures these parameters are present before calling the API.

Yes, the tool integration is model-agnostic. You can use it with OpenAI, Anthropic, Gemini, or local models running on your own infrastructure.

The Vinkius MCP host executes the server within an ephemeral V8 Isolate. Your shipping addresses and phone numbers are never logged or stored on disk.
