How to Use the Joomag MCP in Pydantic AI

Q: How do I connect Joomag to Pydantic AI?

Install pydantic-ai-slimmcp. Pass your endpoint into MCPToolset("http://...") and add it to the toolsets array on your Agent.

Q: Does Pydantic AI support the older Joomag MCP Server setup?

No. MCPServerHTTP is deprecated. You must use the unified MCPToolset approach for external servers running via Streamable HTTP or SSE.

Q: How does my Pydantic AI agent verify Joomag API access?

Use the getaccount tool. It retrieves account details to serve as a fast system health check before your agent attempts heavier operations.

Q: Can I group publications by theme?

The listcollections tool handles hierarchical organization. It lists all publication collections so your agent can navigate thematic groupings accurately.

Q: Are my CRM records protected during MCP Server execution?

The server reads names and emails through listcontacts. Vinkius handles the authentication and routes requests through an ephemeral sandbox, meaning the data never touches a persistent disk.

Perplexity

Type-safe Joomag publication lookups

The `get_publication` tool returns metadata, branding settings, and access configurations for a specific digital publication. Pydantic AI validates every field in this response against your defined models at runtime. If the API returns unexpected branding formats, the agent fails loudly with a validation error. You never have to worry about silent corruption when querying `list_publications` for titles and IDs.

Track release history with this MCP Server

The `list_issues` tool pulls the content history and specific issue IDs for your magazines or catalogs. Your agent relies on this to find exact version releases without hallucinating IDs. Once the correct ID is verified, `get_issue` retrieves the deep-dive details for that specific edition. Because Pydantic AI is model-agnostic, you can run this exact lookup flow using local models or Anthropic.

Validate CRM and campaign metrics

The `list_contacts` tool extracts names, emails, and subscription statuses for audience audits. Every contact record gets checked against your strict schema constraints before the agent processes it. For performance tracking, `list_analytics` handles views and engagement trends, while `list_campaigns` monitors distribution efforts. If a campaign metric comes back as a string instead of an integer, the framework catches it immediately.

Setup guide

Set up Joomag 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({
