Perplexity

Enforce strict type validation on hosting checks

The `check_green_hosting` tool checks the green hosting status of any domain and returns structured JSON. Pydantic AI validates this response against strict Python models at runtime, preventing silent data corruption across MCP server integrations. If the server returns unexpected data, your agent raises a validation error immediately. This ensures your sustainability reports are built on clean, validated data instead of guessed fields.

Connect Pydantic AI to the Green Web Check MCP Server

The `check_green_hosting` tool integrates with your agent via the `MCPToolset` class. You pass the server URL to the toolset and register it directly with your agent. This unified setup replaces deprecated HTTP server classes. It works across different LLM providers, meaning you can switch your underlying model without rewriting your sustainability tool logic.

Run safe asynchronous domain audits

The `check_green_hosting` tool runs within asynchronous agent loops to check multiple domains in parallel. Pydantic AI manages the async execution, making bulk sustainability audits fast and reliable. The framework ensures that even under heavy load, every single API response matches your expected schema. You get fast, type-safe execution without worrying about malformed JSON from the model.

Setup guide

Set up Green Web Check 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": {
        "green-web-check-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Green Web Check transactions")
print(result.output)

Common questions about Green Web Check MCP in Pydantic AI

Use the `MCPToolset` class with the server HTTP URL. Pass this toolset to your `Agent` constructor in the `toolsets` list. Do not use the deprecated MCPServerHTTP class.

The framework validates all incoming data. If the response does not match the expected schema, Pydantic AI throws a validation error, stopping the agent before it can output bad data.

Yes, but the server must be running externally. You point the `MCPToolset` to your local or hosted HTTP endpoint to let your agent access the green hosting tool.

Yes, Pydantic AI is model-agnostic. You can use the green hosting tool with Anthropic, Gemini, or local models, and the framework will still enforce type safety on every check.

Yes. The domain names and URLs you pass to the tool are processed in a secure, ephemeral V8 isolate. They are never cached, stored, or used for training, ensuring your compliance checks remain private.
