Show HN: Ethereum-rpc-mcp – Let Cursor Talk to Any EVM Chain

3 points by Phillip-Kemper 6 hours ago

I built a MCP server using the Typescript SDK that wraps around the JSON RPC methods for EVM Blockchains. Without any extra documentation the LLM is able to interact with the EVM blockchain even through a complex series of requests. To get going, just add the following command to your MCP client of choice (e.g. Cursor)

- npx -y ethereum-rpc-mpc [Optional: RPC_URL]

It works out of the box with any EVM chain.

Example usage with Claude: "What's the ETH balance of 0x742d35Cc6634C0532925a3b844Bc454e4438f44e?" "Is 0x6B175474E89094C44Da98b954EedeAC495271d0F a smart contract?" "Is 0x6B175474E89094C44Da98b954EedeAC495271d0F a smart contract? If yes, what kind of contract is it?"

Appreciate any feedback, this is early work!
