Strict type-safe vehicle audits in Pydantic AI

Validate every API response against your Pydantic models. Use `get_vehicle_details` to ensure the registry data matches your expected schema. If the data format changes or looks wrong, the agent stops execution. This prevents bad data from corrupting your compliance logs.

Verify MOT and tax status with runtime validation

Run `get_vehicle_mot_status` and `get_vehicle_tax_status` to confirm fleet legality. Pydantic AI ensures the returned dates and status strings are correct. You get immediate feedback if the registry returns unexpected values. It turns a standard API call into a dependable data point for your audit trail.

Automate specs and emissions reporting

Pull vehicle specifications and environmental data into your model. Use `get_vehicle_specifications` to get engine and weight metrics with full type enforcement. Clean data goes into your system every time. The server provides the tools, and your Pydantic models enforce the structure of the output.

Setup guide

Set up DVLA Vehicle API 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": {

Common questions about DVLA Vehicle API MCP in Pydantic AI

When you define your agent, the tool outputs are automatically validated by Pydantic. If the API response doesn't fit your model, the agent raises a validation error.

Absolutely. Since the MCP tools provide structured JSON, Pydantic AI maps the fields directly to your defined models for runtime verification.

By using the `MCPToolset`, you provide a clear interface. The agent only executes tools that you have approved and mapped to your data models.

Your Pydantic model will catch the missing field and trigger an error. This prevents your agent from making decisions based on incomplete vehicle information.

The server processes your registration numbers in an ephemeral Vinkius sandbox. Your data is handled per-request and is never stored on the server side.
