How to Use the BlockPi (Distributed RPC Network) MCP in LlamaIndex

Q: Can I index the output of BlockPi (Distributed RPC Network) calls into a LlamaIndex vector store?

Absolutely. You can take the raw JSON strings returned by rpccall and pass them directly to LlamaIndex document parsers. This turns real-time blockchain data into searchable vector embeddings.

Q: How does LlamaIndex use BlockPi (Distributed RPC Network) to prevent AI hallucinations?

By querying live data through rpccall before answering. Instead of letting the model guess contract balances, LlamaIndex pulls the exact state from the distributed network and inserts it as context.

Q: Is it possible to filter BlockPi (Distributed RPC Network) tools in my LlamaIndex agent?

Yes, you can use the allowedtools filter when setting up your McpToolSpec. This lets you restrict your agent to only read-only actions like getrubalance while blocking write operations.

Q: How do I handle large RPC payloads when building index nodes?

You can configure your MCP adapter to chunk the output of rpccall if the payload is massive. This ensures the retrieved blockchain data fits neatly within your model's context window.

Index live blockchain state into your LlamaIndex vector store using this MCP Server for hallucination-free Web3 RAG.

Live Blockchain Context for LlamaIndex RAG

Turn raw blockchain state into searchable knowledge. By calling `rpc_call`, your LlamaIndex pipelines can fetch transaction details or contract states and instantly index them for semantic search. This stops your agent from guessing or relying on outdated training data. It gets the current state of the chain directly from distributed nodes, ensuring your RAG answers are grounded in real-time truth.

Budget-Aware Query Engines

This MCP Server allows your indexing loops to monitor their own resource usage. Before kickstarting a massive data ingestion job, your agent can check `get_ru_balance` to make sure there are enough Request Units left. If the balance is running thin, the agent can scale back its query depth. It keeps your vector store updates predictable without unexpected API shutdowns.

Automated Package Monitoring

Keep track of your active subscription lifecycles directly within your indexer. Using `get_package_expiration` and `get_wallet_balance`, your agent can flag when a package is about to expire. Instead of manually checking dashboards, your LlamaIndex application can write these expiration events directly to its logs or alert systems. This keeps your data pipelines running without silent failures.

Setup guide

Set up BlockPi (Distributed RPC Network) 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 BlockPi (Distributed RPC Network) 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 BlockPi (Distributed RPC Network) tools.",
)
response = await agent.run("List recent BlockPi (Distributed RPC Network) data")
