Type-safe alert validation with Pydantic AI

The `list_alerts` tool returns a structured list of pending site anomalies that your agent must triage. This MCP server handles the incoming payload, and Pydantic AI validates it against strict schemas at runtime, guaranteeing no malformed data slips through. If the data matches the schema, your agent uses `get_change` to pull the precise structural diff. This strict validation prevents silent failures when parsing complex visual change records.

Guaranteed schema compliance for page setup

The `add_page` tool registers new URLs for monitoring under a strict type contract. Your agent cannot pass malformed URLs or invalid parameters, as the framework blocks non-compliant inputs before hitting the network. To verify the registration, the agent calls `get_site` to inspect the live configuration. Every field, from crawl frequency to selectors, is validated to match your internal Python models.

Structured crawl execution and categorization

The `initiate_crawl` tool starts an immediate scan of your targets, returning structured status updates. Your agent tracks the crawl's progress, failing loudly if the response format deviates from the expected type. To organize your targets, the agent uses `create_category` and validates the resulting structure with `list_categories`. This ensures your monitoring taxonomy remains clean and predictable.

Setup guide

Set up Fluxguard 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": {
        "fluxguard-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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