Indexing Card Details for RAG

Don't just look up a card. Index it. Use `get_card_info` to pull data, and then feed that output into your knowledge base index. When you query later, the agent pulls answers grounded in this actual API data. This means if you ask about 'Blue-Eyes White Dragon' and its set history, LlamaIndex grounds the answer using the specific details retrieved by `get_card_info`.

Searching Card Sets Semantically

Listing all card sets with `list_card_sets` is one thing; indexing them is better. The agent uses this list to build a searchable knowledge graph of available collections. When you search, the index combines data from multiple sources—like set names and archetype lists—giving highly accurate context beyond simple keyword matching.

Contextualizing Archetypes

Use `list_archetypes` to get every card type available. The key here is that the output of this tool becomes part of your searchable index, not just a temporary variable. This allows you to query across all known archetypes simultaneously, letting you ask complex questions like 'What cards share properties X and Y?'

Setup guide

Set up Yu-Gi-Oh MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Yu-Gi-Oh MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Yu-Gi-Oh tools.",
)
response = await agent.run("List recent Yu-Gi-Oh data")

Common questions about Yu-Gi-Oh MCP in LlamaIndex

LlamaIndex takes the structured results from the MCP Server and transforms them into a queryable index. You can then ask questions about card history that go beyond what was in the initial prompt.

It doesn't hallucinate. The system is designed to ground every answer in the actual API data pulled from the MCP Server. If the information isn't there, you get that answer.

Absolutely. By indexing the results of `list_card_sets`, your agent can answer queries about set groupings and relationships across different cards.

It's specialized. While other systems might just execute a single API call, LlamaIndex ensures those results are persistent and searchable for future queries.

The index handles card names, set metadata, archetype details, and full card descriptions. All this rich text is available for semantic querying.
