How to Use the GoTab MCP in Pydantic AI

Q: How do I register the GoTab MCP Server with Pydantic AI?

Install pydantic-ai-slimmcp and use the unified MCPToolset class pointing to your Vinkius HTTP URL. Pass the MCP Server toolset object directly into your agent's toolsets list.

Q: Can I use Pydantic AI to validate GoTab item updates?

Yes, you can define strict schemas for updateitemstatus arguments. This guarantees your agent only sends valid availability states to the GoTab API.

Build type-safe restaurant agents with Pydantic AI that validate GoTab menu and order data at runtime.

Parse GoTab menus with Pydantic AI validation

The `get_menu` and `list_categories` tools return structured restaurant data that Pydantic AI validates against strict type definitions at runtime. If your agent tries to read a menu and receives malformed data, the framework fails loudly instead of letting your agent hallucinate. This type-safe approach ensures your digital menu boards always display exact prices and descriptions. Your agent calls `get_item` with complete confidence, knowing the returned fields match your Python schemas exactly.

Manage guest tabs using Pydantic AI

The `get_tab` and `list_tabs` tools let your agent audit open guest accounts without risking calculation errors. Pydantic AI enforces type checks on every currency field and item count returned by this MCP Server. Because the framework rejects unexpected API payloads, you never have to worry about an agent misinterpreting a tab balance. If a payment status field doesn't match your schema, the system catches it instantly.

Update item status with zero-trust validation

The `update_item_status` tool lets your agent toggle dish availability based on strict operational rules. Your agent checks current stock using `list_items` and updates the POS system only when all Pydantic validation checks pass. This direct integration prevents corrupted status updates from breaking your online ordering flow. The agent uses Pydantic AI's model-agnostic validation to ensure the status string matches your database expectations.

Setup guide

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

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

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