Type-safe math for Pydantic AI

Every response from the `calculate_bollinger_bands` tool gets validated against your models. If the output doesn't match, Pydantic AI throws an error immediately. This stops bad data from propagating through your agent. You get clean, typed results every single time.

MCP Server runtime validation

Use the MCPToolset to bring the engine into your agent. It works with any model you choose, while keeping your data structures locked down. Development becomes predictable. You define the schema, and the server provides the numbers to fill it.

Standardized toolsets for Pydantic AI

Stop worrying about silent corruption. This tool ensures that the upper, middle, and lower bands are always valid numbers before your agent sees them. Plug it in, define your Pydantic model, and let the agent handle the rest. It's built for developers who demand accuracy.

Setup guide

Set up Bollinger Bands Engine 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({

            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Bollinger Bands Engine transactions")
print(result.output)

Common questions about Bollinger Bands Engine MCP in Pydantic AI

It provides strict data types. Pydantic AI validates these against your schemas, preventing weird errors during runtime.

You install the slim package, define your toolset with the server URL, and pass it to your agent constructor.

No, it's model-agnostic. You can switch between local models and APIs without changing your tool logic.

Your Pydantic model will fail validation. The agent will catch this, letting you debug the issue before it breaks your logic.

The server operates in an ephemeral sandbox. It processes your array and discards it, ensuring no persistent storage of your inputs.
