Overview

What is Ethereum RPC MPC Server?

A TypeScript MCP server that bridges AI assistants (Cursor, Claude) with EVM blockchains by exposing all standard Ethereum JSON-RPC methods. It enables AI models to query on-chain data like block numbers, balances, contract details, and transactions through natural language.

How to use Ethereum RPC MPC Server?

Install via git clone, yarn install, and yarn build. Start with yarn start [RPC_URL] [CHAIN_NAME] or run npx -y ethereum-rpc-mpc [RPC_URL] [CHAIN_NAME]. In Cursor, add a new MCP server with command: npx -y ethereum-rpc-mpc https://eth.llamarpc.com Ethereum. Optional --analytics flag enables request logging to a SQLite database.

Key features of Ethereum RPC MPC Server

Supports all standard Ethereum JSON-RPC calls.
Works with any EVM-compatible blockchain.
Automatic activation of Zircuit-specific RPC methods.
Optional analytics middleware for request monitoring.
Simple CLI invocation via npx without install.
TypeScript implementation using the MCP SDK.

Use cases of Ethereum RPC MPC Server

Query the current block number using natural language.
Check ETH balances of any address in real time.
Retrieve transaction details for a given hash.
Verify if an address is a smart contract and its type.
Monitor Zircuit transaction quarantine status.

FAQ from Ethereum RPC MPC Server

What RPC endpoint does it use by default?

The default RPC URL is https://eth.llamarpc.com if none is provided.

Which chains are supported?

Any EVM-compatible blockchain can be used by supplying a custom RPC URL and chain name (e.g., https://mainnet.zircuit.com Zircuit).

How do I enable Zircuit-specific methods?

Zircuit methods (zirc_isQuarantined, zirc_getQuarantined) are automatically activated when connecting to a Zircuit endpoint (Chain ID 48900).

What are the runtime requirements?

Node.js and TypeScript. The server is distributed as an npm package and can be run via npx without a local install.

Can I connect to multiple chains at once?

Currently the server supports a single RPC endpoint per session. Multi-chain and multi-RPC support is planned for future versions.
