How to Use the CardanoScan (Cardano Block Explorer API) MCP in LlamaIndex

Q: How do I connect CardanoScan (Cardano Block Explorer API) to LlamaIndex?

Install llama-index-tools-mcp and initialize the BasicMCPClient with your Vinkius URL. Convert the tools using McpToolSpec and pass them to your FunctionAgent to start querying the blockchain.

Q: Can I use CardanoScan (Cardano Block Explorer API) to ground LlamaIndex RAG queries?

Yes, the agent uses gettransaction to fetch live transaction payloads and injects them directly into the LLM context window. This ensures your answers about ledger events are 100% accurate.

Q: How do I search for specific assets using CardanoScan (Cardano Block Explorer API) in LlamaIndex?

The agent invokes getasset to retrieve token metadata and policy details. It then indexes this data so your users can search for native assets using natural language.

Q: Does this setup support filtering specific tools?

Yes, you can use the allowedtools filter in LlamaIndex to restrict the agent to specific tools like getepoch over the MCP connection.

Index live Cardano ledger state directly into your LlamaIndex vector stores.

Build RAG apps with CardanoScan MCP Server data

This MCP Server exposes `get_asset` and `list_asset_transactions` to let your LlamaIndex pipeline pull live native asset data directly into its index. You feed the real-time transaction history of any Cardano token straight into your vector database to ground your RAG applications in ground-truth ledger data. Your query engine retrieves these actual on-chain events instead of relying on outdated training data. This completely eliminates hallucinations when users ask about recent token transfers or minting events.

Auto-index Cardano blocks in LlamaIndex

The `get_block` and `get_latest_blocks` tools allow your LlamaIndex agent to monitor the blockchain and index new block data on the fly. It converts raw block payloads into searchable document nodes for semantic search. You can query your knowledge base to find patterns in block generation or transaction density over time. The agent handles the ingestion and structure mapping without requiring custom parser scripts.

Semantic search over Cardano stake pools

Your indexer uses `list_pools` and `get_pool` to build a local, searchable index of all active Cardano stake pools. LlamaIndex matches user queries like "low fee pools with high pledge" against the indexed pool metadata. This turns raw API responses into a structured knowledge graph. Your agent queries this graph to give users accurate, context-rich recommendations based on live registry data.

Setup guide

Set up CardanoScan (Cardano Block Explorer API) 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 CardanoScan (Cardano Block Explorer API) 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 CardanoScan (Cardano Block Explorer API) tools.",
)
response = await agent.run("List recent CardanoScan (Cardano Block Explorer API) data")
