How to Use the Aimtell MCP in Pydantic AI

Q: How do I fetch active push campaigns using Aimtell and Pydantic AI?

Your agent calls listcampaigns to retrieve your active push templates. The framework automatically parses the response into a structured list of campaigns for safe usage.

Validate every push campaign and subscriber update at runtime with Pydantic AI type safety.

Validate subscriber data with Pydantic AI

`get_subscriber_details` fetches metadata for a specific user and parses it into strict Python models. If the API returns unexpected fields or malformed data, your agent catches the validation error instantly. This rigorous runtime checking prevents corrupt data from polluting your downstream systems. You write cleaner code because the framework guarantees the structure of every subscriber record.

Track campaign metrics with type safety

`get_campaign_performance` returns push campaign statistics that conform exactly to your defined schemas. Your agent uses these typed metrics to make decisions about which campaigns need adjustments. The MCP Server handles the raw API communication while the framework ensures the response matches your expectations. You avoid silent failures where a missing field breaks your reporting logic.

Run API campaigns with zero schema drift

`list_api_campaigns` lists your active developer-triggered push notifications and validates them against strict types. This MCP setup ensures your agent always works with current, valid campaign IDs. Since the framework is model-agnostic, you can swap your underlying LLM from OpenAI to Anthropic without changing your validation logic. Your push workflows remain stable regardless of the model you choose.

Setup guide

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

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

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