How to Use the Megaphone MCP in Pydantic AI

Q: Why use Pydantic AI to connect to the Megaphone MCP Server?

It guarantees that the data returned from tools like listcampaigns matches your models. If the API returns invalid data, the agent fails cleanly with a validation error.

Q: How do I set up the Megaphone MCP Server with Pydantic AI?

You instantiate an MCPToolset with your server's URL. Once added to your agent's toolsets list, every response from the server is automatically validated against your defined models.

Enforce strict schema validation on your Megaphone data by using the Pydantic AI MCP Server integration.

Type-safe podcast management with Pydantic AI

Your agent uses `get_podcast` and `list_podcasts` to retrieve metadata while our models validate every field against your Pydantic schemas. If the API output deviates, you get an immediate error instead of silent data failure. This keeps your agent's state consistent. You know exactly what data you're working with, whether you're pulling from `list_networks` or `get_network_details`.

Verified ad campaign data for Pydantic AI

Stop worrying about hallucinated fields when reading `list_campaigns` or `list_orders`. Your agent enforces strict types on all ad-related data, preventing runtime crashes in your pipeline. You can trust your inventory counts from `list_ad_locations` because the schema validation catches discrepancies instantly. It's the safest way to manage monetization logic programmatically.

Strict episode search and indexing

Every result from `search_episodes` is validated before your agent even sees it. This ensures your content indexing logic is never broken by unexpected API changes. Use `list_episodes` or `get_episode` with confidence. Your agent is protected from bad data, allowing you to build reliable content workflows that actually work under pressure.

Setup guide

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

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

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