How to Use the Amiibo MCP in Pydantic AI

Q: How do I connect Pydantic AI to the Amiibo MCP Server?

Pass your Vinkius endpoint into MCPToolset using the HTTP prefix. Assign that toolset to your Agent constructor and the tools become available immediately.

Q: Does Pydantic AI validate the Amiibo search results?

It strictly enforces the schema. If listamiibos returns an unexpected data structure, the framework throws a validation error before the agent tries to process it.

Q: Can my Pydantic AI agent look up specific Amiibo characters?

Your agent will use listcharacters to find valid names. It then passes those verified strings into the main search tool to retrieve the exact figures.

Bring strict type safety to Nintendo figure queries using Pydantic AI and the Amiibo MCP Server.

Validate Amiibo data at runtime

Silent data corruption destroys agent reliability. When your model queries this server, every response gets validated against Pydantic models instantly. If Nintendo's API changes a field type, your agent fails loudly instead of passing bad data downstream. Setup is dead simple. You install the slim package, point `MCPToolset` at your Vinkius URL, and attach it to your Agent. The framework handles the Streamable HTTP transport while enforcing strict schemas on endpoints like `get_amiibo`.

Query the Amiibo MCP Server with any LLM

You are not locked into one provider. You can run Claude, OpenAI, or a local Llama model. When interacting with this MCP Server, the framework translates the tool calls perfectly across different model formats. Agents can execute complex filter chains. A local model might call `list_game_series` first to verify a franchise name, then use that exact string with `list_amiibos` to pull all associated figures. The type checking guarantees the parameters match the required input schema.

Track database updates reliably

Knowing when data changes matters just as much as the data itself. Your agent can ping `get_last_updated` to check the current database timestamp. It stores this state and only runs expensive bulk queries when new figures actually drop. Getting lists of distinct categories is just as safe. Calls to `list_amiibo_series` or `list_types` return clean, validated arrays. Your application logic never has to guess if the model hallucinated a card type that does not exist.

Setup guide

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

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

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