How to Use the Corsizio MCP in Pydantic AI

Q: Can Pydantic AI agents check for active Corsizio discount codes?

Yes, the agent calls the listcoupons tool to retrieve all active discount codes and their expiration boundaries. It validates the coupon details before applying them to a registration flow.

Q: How does Pydantic AI search for specific Corsizio attendees?

The agent uses the listattendees tool to pull the roster for any event. It can filter the validated list by payment status or registration date to find exactly who you need.

Type-Safe Corsizio Operations via MCP Server

The `get_attendee_details` tool fetches registration profiles, payment histories, and event boundaries for any registered user. Because you are using Pydantic AI, the incoming JSON payload is validated against strict schemas before your agent even sees it. This prevents runtime errors caused by missing fields or unexpected data formats. If an attendee record has an empty email field, the framework catches it immediately, so you don't end up with broken records.

Track Event Schedules and Capacities

The `get_event_details` tool retrieves the exact setup, pricing structure, and registration limits for any class. Your agent uses this data to answer user questions about seat availability or ticket pricing. Combine this with `list_events` to build an automated monitoring script. The script checks which workshops are nearing capacity and alerts your team to open new sessions.

Reconcile Payments and Refunds

The `list_payments` tool resolves transaction IDs, payment amounts, and currencies across your entire account. Your agent can cross-reference these records with external bookkeeping systems to automate financial reporting. When handling disputes, the agent uses `list_refunds` to check if a transaction was already reversed. This keeps your refund process transparent and prevents double-refunding customer accounts.

Setup guide

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

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

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