How to Use the NVIDIA NIM MCP in Pydantic AI

Q: Does Pydantic AI validate the output of NVIDIA NIM health checks?

Yes, tool outputs from nimcheckhealthlive are parsed directly into typed models. Your agent gets verified boolean statuses instead of raw, unpredictable strings.

Q: Can Pydantic AI handle raw Prometheus metrics from NVIDIA NIM?

The agent calls nimgetmetrics to retrieve structured performance telemetry. Pydantic AI validates the metrics payload, ensuring float values and counter names conform to your schemas.

Q: How does the agent handle container logs?

Your agent calls nimgetcontainerlogs to fetch stdout streams. The framework ensures the log strings are cleanly formatted before passing them to your debugging workflows.

Run type-safe GPU monitoring and scaling operations inside your Pydantic AI agent workflows.

Validate GPU status using Pydantic AI schemas

Calling `nim_get_gpu_status` parses physical GPU topological limits and active memory variables. Because this runs inside Pydantic AI, every returned VRAM value is strictly validated against your Python type models.\n\nIf the hardware reports an unexpected memory format, the agent raises a validation error immediately. This prevents corrupted hardware data from breaking downstream routing logic.

Type-safe replica scaling with this MCP Server

This MCP Server uses `nim_scale_replicas` to update the active container count to handle shifting user demand. Your agent executes this operation with strict integer bounds validation.\n\nNo invalid replica counts can be sent to the cluster. The agent monitors the scaling progress using `nim_check_health_ready` to ensure new instances are fully initialized before routing traffic.

Audit running models and metadata

Executing `nim_list_models` returns a verified list of active LLMs running on your local backend. The agent checks this list to ensure target models are online before initiating user sessions.\n\nTo confirm the exact configuration of those models, `nim_get_metadata` pulls engine execution bounds. Your agent uses this data to verify that max sequence lengths match your application requirements.

Setup guide

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

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

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