Ethereum Wallet Generator
Exposes Ethereum wallet operations through five focused MCP servers: wallet generation with BIP39 mnemonics and HD derivation paths, keystore encryption using Web3 Secret Storage format with scrypt/pbkdf2, message signing for EIP-191 and EIP-712 typed data, transaction building for legacy and EIP-1559 formats with RLP encoding, and validation utilities including EIP-55 checksums and keccak256 hashing. Ships with 57 tools total and 348 tests. Built on official ethereumjs libraries. Reach for this when you need Claude to generate vanity addresses, sign transactions offline, manage encrypted keystores, or validate addresses and signatures without touching the network. Everything runs locally over stdio transport.

Ethereum Wallet Toolkit
A collection of Ethereum wallet tools: Python CLI utilities (eth_toolkit.py, wallet.py, keystore.py, sign.py, transaction.py, typed_data.py, validate.py, vanity.py), five Model Context Protocol (MCP) servers exposing wallet functionality to AI assistants, a fully offline single-file HTML wallet (offline.html), and an x402 payment facilitator. See the sections below for each component.
