Index Cronoscan data with LlamaIndex

Pipe the results of `get_logs` or `get_tx_list_internal` directly into your vector store. LlamaIndex treats these blockchain events as searchable documents, creating a history of activity you can query later. This turns transient blockchain data into a long-term knowledge base. Your agent answers questions based on actual events rather than guessing.

Build RAG apps with Cronoscan and LlamaIndex

Combine `proxy_eth_call` results with your own documentation in a unified index. This allows your agent to compare live network state against static project requirements. It bridges the gap between what the chain says and what your docs say. You get a RAG agent that understands the current reality of the Cronos ecosystem.

Query past Cronoscan sessions in LlamaIndex

Save the output of your blockchain investigations into your index for future retrieval. When you run `get_token_nft_tx`, the data is indexed for semantic search. You can ask your agent about previous NFT transfers weeks later. It makes your LlamaIndex setup a powerful archive for blockchain research.

Setup guide

Set up Cronoscan (Cronos Block Explorer) 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 Cronoscan (Cronos Block Explorer) 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 Cronoscan (Cronos Block Explorer) tools.",
)
response = await agent.run("List recent Cronoscan (Cronos Block Explorer) data")
