Validate your EmailOctopus contacts with Pydantic AI

This MCP Server enforces strict schemas when your agent calls `add_contact_to_list` or `update_contact_profile`. Malformed contact profiles will never break your marketing database again. When your agent triggers these tools, the response is validated at runtime. If the API returns unexpected data, your Python code raises a validation error immediately.

Parse campaign metrics without silent errors

The agent uses `get_campaign_summary_report` and `get_campaign_details` to pull reliable performance data for your internal dashboards. Fetching analytics becomes safe because every key-value pair is checked against strict types. Because Pydantic AI validates the structure of the incoming JSON, you avoid silent data corruption. Your reporting pipelines stay green because the schemas are guaranteed.

Manage subscriber lists with runtime schema checks

The agent queries your lists via `list_email_lists` and retrieves specifics with `get_list_details`. Hallucinated fields are caught before they can affect downstream logic. Every field returned by this MCP Server is typed. If you try to access a non-existent property on a subscriber list, the compiler or the runtime validator will catch it instantly.

Setup guide

Set up EmailOctopus 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": {
        "emailoctopus-alternative-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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