Multi-Step Card Lookup Pipelines

Need to figure out a card’s history? Start by running `get_card_info` to grab the basic details. Then, chain that output immediately into `get_card_set_info` to pinpoint exactly which set it came from. This sequence lets your agent build complex reasoning chains without needing manual steps. You're not just calling tools; you're building a workflow where one tool’s result feeds the next.

Systematic Card Discovery

Want to browse systematically? First, run `list_archetypes` to get all available card types. After that, use `list_card_sets` so you know what collections exist. Your agent can now combine these lists to narrow down the search space before finally calling `get_card_info` on a specific group of cards. It’s about sequential decision-making.

Random Card Analysis

Don't know what you want? Call `get_random_card` to pull an arbitrary card name right away. From there, your agent can use that result as input for several other tools. It might run `list_archetypes` against the random card's type, or check its set using `get_card_set_info`. This makes exploring the database feel like a real playthrough.

Setup guide

Set up Yu-Gi-Oh MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes Yu-Gi-Oh tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "yu-gi-oh-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent Yu-Gi-Oh transactions"
    })
    print(result["messages"][-1].content)

Common questions about Yu-Gi-Oh MCP in LangChain

The agent treats all card data—the set name, the archetype, and the individual card details—as structured input. You can write a chain where getting random card info leads directly to checking that card's full set context.

Rate limits depend on your Vinkius subscription and overall usage pattern. The MCP Server handles the connection stability, but you should always monitor token usage when building complex chains.

Yes. You can build a multi-step pipeline where the output of `get_card_info` is used as context for a subsequent call, essentially querying related information in sequence.

It's different. Instead of just retrieving data like a simple API wrapper, the MCP Server lets your agent decide *which* tools to call and in what order based on intermediate results.

This server touches card names, set identifiers, archetype lists, and detailed card properties. All this structured metadata is available for your agent to process.
