Strict runtime validation with Pydantic AI

Stop letting your agents hallucinate environmental metrics. This MCP server exposes `get_air_quality` to fetch live AQI data, and Pydantic AI validates every single field against strict Python types before your code runs. If the underlying API returns unexpected data formats, your agent fails loudly and instantly. This prevents corrupted pollution metrics from silently poisoning your downstream data pipelines.

Type-safe pollen monitoring via `get_pollen_levels`

Track environmental allergens without worrying about schema drift. Your agent calls `get_pollen_levels` to fetch current tree, grass, and weed pollen data as structured Pydantic models. This structure ensures your agent always knows the exact data type it is dealing with. You can write clean, type-safe logic to handle high pollen alerts without manual dictionary parsing.

Unified MCP Server integration

Connect your agent to the server using the modern `MCPToolset` class. This unified approach eliminates the deprecated HTTP client setup and registers the tools in a single line of code. The toolset handles the SSE or streamable HTTP transport under the hood. Your agent gets instant access to the environmental tools while maintaining complete model-agnostic flexibility.

Setup guide

Set up BreezoMeter Air Quality & Pollen 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": {
        "breezometer-air-quality-pollen-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to BreezoMeter Air Quality & Pollen tools.",
)

result = await agent.run("List recent BreezoMeter Air Quality & Pollen transactions")
print(result.output)

Common questions about BreezoMeter Air Quality & Pollen MCP in Pydantic AI

Create an `MCPToolset` instance pointing to the MCP server URL, then pass it in the `toolsets` list when defining your `Agent`. The tools register themselves automatically.

The framework will throw a validation error at runtime. This guarantees your agent never processes malformed air quality or pollen payloads.

Yes. Because Pydantic AI is model-agnostic, you can use these environmental tools with local models, OpenAI, Anthropic, or Gemini.

Use the streamable HTTP or SSE transport options. The unified `MCPToolset` handles the connection details automatically behind the scenes.

Yes. The server only uses the geographic coordinates to fetch current pollen and air quality levels. Vinkius isolates each request in a zero-trust sandbox, ensuring no location data is cached or leaked.
