Type-safe subscriber management with Pydantic AI

Stopping malformed user data from breaking your email lists is straightforward when your agent uses `add_subscriber` to validate fields at runtime. When your agent calls this endpoint, this MCP Server validates the email format and custom fields on the fly. If the API returns unexpected field types, the framework raises a validation error immediately. This prevents bad data from corrupting your subscriber database.

Validated campaign tracking

Ensuring your analytics reporting is always structured correctly starts when your agent uses `get_campaign_analytics` and `get_list_statistics` to fetch performance numbers. These tools return data that matches strict schemas. The model-agnostic nature of the framework means you can swap LLMs behind the scenes. Your data parsing logic won't break because the schemas are enforced by Python code, not prompt engineering.

Structured client audits

Pulling agency data with complete type safety begins when the agent invokes `list_clients` and `list_subscriber_lists` to map out your account structure. The agent maps out your account structure without risking runtime crashes. Every client ID and list name is parsed into a verified Python model. Your agent can confidently pass this data to downstream functions, knowing `get_subscriber_details` won't fail due to a missing field.

Setup guide

Set up Campaign Monitor 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": {
        "campaign-monitor-alternative-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

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