Perplexity

Type-safe control for Pydantic AI

Run `lock_doors` and `stop_vehicle` with the guarantee that your agent's input matches the required schema. Pydantic AI validates every response at runtime. If the API returns malformed data, the system triggers an error immediately. You avoid the risks of silent failures when managing physical vehicle state.

Validated diagnostic streams

Get accurate `get_tire_pressure` and `get_odometer` readings mapped to strict Python types. You can trust the data flowing into your agent's logic. This prevents hallucinated fields or unexpected types from breaking your fleet monitoring. It is the safest way to handle sensitive vehicle health information.

Reliable vehicle discovery

Use `get_vehicles` to fetch your fleet list into a validated Pydantic model. Your agent always knows exactly which vehicle it is talking to. This eliminates ambiguity when you have multiple vehicles on one account. The toolset ensures you are always targeting the correct VIN for navigation or status commands.

Setup guide

Set up General Motors 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": {
        "general-motors-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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