Type-safe contact ingestion with Pydantic AI

`create_contact` ensures that every user record added to your marketing lists matches your exact schema. Pydantic AI validates the email, phone number, and custom attributes before the tool executes. If your agent attempts to write corrupted data, the framework halts the execution immediately. This strict validation prevents database pollution and API errors down the line. When running `create_contact_attribute`, you define strict types that the agent must respect. You get clean, predictable contact directories without manual data cleaning.

Runtime validation for transactional emails

`send_transactional_email` executes critical user notifications through this MCP Server with absolute structural certainty. Pydantic AI checks the recipient fields, template IDs, and template variables against your strict Python models. This guarantees that no user receives an email with broken placeholders or missing values. If the LLM generates an invalid payload, the framework raises a validation error instead of sending a broken message. You catch formatting issues during the agent's reasoning loop, keeping your customer communications professional and accurate.

Structured webhook and campaign tracking

`create_webhook` allows your type-safe agents to subscribe to delivery events and process incoming webhooks reliably. The agent configures the endpoints and monitors status updates using `get_webhook`. Every event payload is parsed into a Pydantic model for safe consumption. You track campaign performance by pulling structured reports through `get_email_statistics_reports`. Because the data is strongly typed, your downstream analytics pipelines can consume the metrics without parsing errors. You build resilient marketing loops that fail safely and loudly.

Setup guide

Set up Brevo Alternative 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": {
        "brevo-alternative-1-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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

Common questions about Brevo Alternative MCP in Pydantic AI

The framework wraps this MCP Server's tool definitions in Pydantic models. Every argument generated by your model is validated at runtime before hitting the messaging APIs.

Pydantic AI catches the structural mismatch immediately and raises a validation error. This prevents your agent from operating on corrupted contact records or invalid campaign states.

Yes, this MCP Server is completely model-agnostic. You can pair it with Anthropic, Gemini, or local models while maintaining strict type safety.

You use the unified MCPToolset class pointing to the streamable HTTP URL. Avoid the deprecated MCPServerHTTP class to ensure compatibility with modern transports.

All transactional emails, phone numbers, and WhatsApp messages are processed in isolated, ephemeral environments. Vinkius handles the MCP authentication token securely, ensuring your raw credentials never touch the LLM provider.
