Overview

What is RPC MCP Server?

RPC MCP Server is a Model Context Protocol server implementation for interacting with any EVM-compatible RPC endpoint. It provides a standardized interface for AI models to interact with Ethereum and EVM-compatible blockchains. It is designed for developers using AI assistants like Cursor to query blockchain data.

How to use RPC MCP Server?

Install via npm (npm install -g .), set the RPC_URL environment variable to your RPC endpoint, then add the server to your Cursor mcp.json configuration. The server exposes tools like eth_blockNumber, eth_getBalance, and eth_call that can be invoked through the MCP client.

Key features of RPC MCP Server

  • Support for any EVM-compatible RPC endpoint
  • Get current block number
  • Check account balances
  • Get transaction counts (nonces)
  • Retrieve block information
  • Get transaction details
  • Make contract calls

Use cases of RPC MCP Server

  • Query blockchain state directly from an AI coding assistant
  • Monitor account balances or nonces during development
  • Debug transactions by fetching block and transaction details
  • Call smart contract functions without leaving the IDE
