Perplexity

Type-safe marketing data retrieval

Every response from `get_dotdigital_account_metadata` is validated against your Pydantic models. If the API structure changes, your agent fails safely rather than processing bad data. This ensures your agent logic always relies on accurate account limits and status codes. It provides a level of correctness that standard integrations lack.

Validating contact searches

When your agent runs `search_marketing_contacts`, the results are parsed into rigid schemas. This prevents hallucinated fields from entering your processing pipeline. It forces the agent to handle missing data or empty results explicitly. Your marketing automation stays reliable even when contact records are incomplete.

Strict oversight of email campaigns

The `get_campaign_details` tool returns data that your agent validates immediately. It checks for expected types across all campaign metrics. This rigorous checking makes your agent predictable. You get the benefits of an MCP Server with the confidence of a type-safe Python framework.

Setup guide

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

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

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