RPC MCP Server

RPC MCP Server

This is a Model Context Protocol (MCP) 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.

Features

• 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

Prerequisites

• Node.js (v16 or higher)
• npm (Node Package Manager)

Installation

1. Clone the repository:

git clone <repository-url>
cd rpc-mcp

2. Install dependencies:

npm install

3. Build the project:

npm run build

4. Install globally:

npm install -g .

This global installation makes the rpc-mcp command available system-wide, which is required for Cursor to find and execute the MCP server.

Configuration

The server uses the following environment variable:

• RPC_URL: The RPC endpoint URL to connect to (e.g., 'https://mainnet-rpc.game7.io' or 'https://testnet-rpc.game7.io')
• API_URL: The API endpoint URL to connect to (e.g., 'https://mainnet.game7.io/api/v2' or 'https://testnet.game7.io/api/v2')

Cursor MCP Configuration

Add the following to your mcp.json file in your Cursor (Settings > MCP > Add New Global Server):

{
  "mcpServers": {
    "rpc-mcp": {
      "command": "npx",
      "args": ["-y", "rpc-mcp"],
      "env": {
        "RPC_URL": "YOUR_RPC_ENDPOINT",
        "API_URL": "YOUR_API_ENDPOINT"
      }
    }
  } 
}

This configuration will make the following tools available in Cursor:

• eth_blockNumber
• eth_getBalance
• eth_getTransactionCount
• eth_getBlockByNumber
• eth_getTransactionByHash
• eth_call
• trace_transaction
