How to Use the Celoscan (Celo Network Explorer) MCP in LlamaIndex

Q: Can LlamaIndex query historical Celo transactions with this Celoscan (Celo Network Explorer) MCP Server?

Yes, it can. Your agent uses geterc20transfers or geterc721transfers to fetch historical events, indexes them, and runs semantic search over the transaction history.

Q: Does this Celoscan (Celo Network Explorer) integration with LlamaIndex support real-time data?

Yes. You can configure your agent to call getblocknumberbytime dynamically using the MCP Server interface.

Index live Celo blockchain records directly into your LlamaIndex RAG pipelines.

Perplexity

Semantic Search Over Smart Contract Code

Forget about digging through raw explorer pages manually. This MCP Server lets your LlamaIndex agent fetch contract source code with `get_contract_source_code` and parse it into vector nodes. You can query your indexed vector store to find specific vulnerability patterns or functions. The agent uses actual verified code from Celoscan to answer technical questions instead of guessing.

Grounding RAG Queries in Celo Network Data

Feed live transaction receipts into your index to eliminate hallucinated block data. Your agent retrieves raw data via `get_normal_transactions` and indexes it on the fly. When you ask about recent wallet activity, LlamaIndex queries this fresh local index. It matches your semantic query with exact transaction records retrieved by `get_internal_transactions`.

Dynamic Balance and Supply Indexing with LlamaIndex

Keep your financial knowledge bases accurate without constant manual exports. The agent queries `get_erc20_token_supply` and `get_total_celo_supply` to update your data store. It then indexes these metrics alongside current token holdings retrieved via `get_erc20_token_balance`. Your downstream queries always fetch the most recent block state.

Setup guide

Set up Celoscan (Celo Network 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 Celoscan (Celo Network 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 Celoscan (Celo Network Explorer) tools.",
)
response = await agent.run("List recent Celoscan (Celo Network Explorer) data")

Common questions about Celoscan (Celo Network Explorer) MCP in LlamaIndex

You load the LlamaIndex MCP tool spec to pull data from tools like `get_normal_transactions`. The output gets converted into document nodes and dumped straight into your vector store.

Yes, it can. Your agent uses `get_erc20_transfers` or `get_erc721_transfers` to fetch historical events, indexes them, and runs semantic search over the transaction history.

Yes. You can configure your agent to call `get_block_number_by_time` dynamically using the MCP Server interface.

Yes. Use the allowed tools filter in LlamaIndex to restrict the agent to specific tools like `get_account_balance` while blocking write or contract inspection tools.

All API calls to Celoscan are executed in a secure, ephemeral sandbox. Your wallet addresses and transaction queries are sent directly to the explorer API via the MCP protocol.
