What is the Ethereum RPC MPC Server?

This is a server based on the Model Context Protocol (MCP), specifically designed to provide AI assistants (such as Cursor or Claude) with the ability to access Ethereum blockchain data. Through a standardized JSON-RPC interface, AI models can easily query blockchain information, account balances, smart contract data, etc.

How to use the Ethereum RPC MPC Server?

You can start the service via a simple command line, and then add the service to the settings of an AI assistant (such as Cursor) to start using it. When starting the service, you need to specify an Ethereum RPC node address.

Use cases

This service is very useful when you need to query blockchain data, analyze transactions, check the status of smart contracts, or obtain real-time on-chain information through an AI assistant. It is particularly suitable for developers, blockchain analysts, and cryptocurrency enthusiasts.

Main features

Full JSON-RPC supportSupports all standard Ethereum JSON-RPC methods, including eth_blockNumber, eth_getBalance, etc.

Multi-chain supportCan connect to different Ethereum-compatible chains (EVM chains), just specify different RPC endpoints

Special support for Zircuit SLSAutomatically detects the Zircuit chain and enables special Sequencer Level Security methods

Analysis functionOptionally enable the analysis function to track the number of requests, duration, and error reports

Advantages and limitations

Advantages

Easy to use - Start the service with just one command

🚀 Ethereum RPC MPC Server

A TypeScript MPC server that uses the MCP SDK to support all Ethereum JSON-RPC calls, enabling AI models to interact with blockchain data.

🚀 Quick Start

This project provides a Model Context Protocol (MCP) server that allows AI assistants like Cursor or Claude (or any MCP client implementation) to interact with Ethereum blockchain data through a standardized JSON-RPC interface. It serves as a bridge between AI models and EVM blockchains, enabling seamless access to on-chain data and functions.

📦 Installation

# Clone the repository
git clone git@github.com:Phillip-Kemper/ethereum-rpc-mpc.git
cd ethereum-rpc-mpc

# Install dependencies
yarn install

# Build the project
yarn build

# Start the inspector with the default Ethereum RPC (can be changed in inspector settings)
yarn inspector

💻 Usage Examples

Basic Usage with Cursor

To use this MPC server with Cursor:

In Cursor, go to Settings > Cursor Settings > MCP.
Add a new MCP server with the following configuration:
- Name: Ethereum RPC
- Type: Command
- Command: npx -y ethereum-rpc-mpc https://eth.llamarpc.com Ethereum Or
- Command: node /path/to/ethereum-rpc-mpc/dist/server/index.js https://eth.llamarpc.com Ethereum

Advanced Usage - Analytics

You can also use the MCP Analytics Middleware to enable analytics for tracking usage, popular RPC methods, and performance metrics. Here's an example command to enable analytics:

# Enable analytics (optional)
npm install --save mcp-analytics-middleware

Future Steps

Support Index API Access in Addition to RPC: We plan to expand the functionality to support access to blockchain data indexing APIs in addition to basic RPC calls. This will make querying historical data and complex on-chain analysis more efficient.
Support Multiple Chains and RPC Endpoints: Future versions will support connecting to multiple chains and RPC endpoints simultaneously, allowing AI models to access data from different blockchains in a single session.
Client Implementation: We plan to develop a client implementation to make it easier for various applications to interact with this MPC server.
Server Analytics: We plan to add analytics to track usage patterns, popular RPC methods, and performance metrics. This will help optimize the server and provide insights into how AI models interact with blockchain data.
