Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
RPC MCP ServerCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
- Node.js (v16 or higher)
- npm (Node Package Manager)
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

Features
- Support for any EVM-compatible RPC endpoint
- Get current block number
- Check account balances
- Get transaction counts (nonces)

- 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
