Type-safe NVIDIA AI interactions

Pydantic AI validates every tool response automatically. If `chat_completion` returns malformed data, your agent catches it before it touches your database. This ensures your agent state remains consistent. You define the schema, and the framework enforces it on every call.

Ask questions with context

The `ask_question` tool allows your agent to pass specific context for better reasoning. It is designed for complex tasks requiring high accuracy. Your agent builds the context, hits the tool, and receives a structured answer. It is a reliable way to get precise information.

Manage model lists via MCP Server

Your agent can query `list_models` to see available NVIDIA AI options. It allows for dynamic selection based on the current task requirements. This keeps your agent flexible. It checks what is available, selects the correct model, and runs the job.

Setup guide

Set up NVIDIA AI 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": {
        "nvidia-ai-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about NVIDIA AI MCP in Pydantic AI

You define your Pydantic models in your agent code. The framework validates the server response against these models at runtime.

It does. You can use SSE or HTTP transports to stream responses. The agent processes the chunks as they arrive.

The server must run externally on Vinkius. Your agent connects to it over the network, keeping your local environment clean.

The agent raises a validation error. This prevents silent failures and ensures your system state remains valid.

The server uses volatile storage that clears after every request. Your prompts are never written to disk or shared with other sessions.
