Pydantic AI schema validation

Every file you fetch with `get_blob` can be parsed into a Pydantic model. If the file structure changes, your agent throws a validation error immediately. This stops the agent from working with corrupted data. It forces a clean state before any logic executes.

Write files with Pydantic AI

The `put_blob` tool accepts your validated data objects. You serialize your Pydantic models to a string and push them to the container. It ensures that the data hitting your storage is always in the expected format. No more guessing what is inside your files.

Audit your Azure Blob Container in Pydantic AI

Use `list_blobs` to audit the container contents. You get a list of file paths back, which you can validate against your internal registry. This is useful for verifying that your storage contains the files your agent expects. It adds a layer of predictability to your pipeline.

Setup guide

Set up Azure Blob Container 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": {
        "azure-blob-container-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Azure Blob Container transactions")
print(result.output)
