About
Ethereum Address Validator is an MCP server that validates Ethereum primitives on demand: addresses and their EIP-55 checksums, private and public keys, keccak256 hashes, 4-byte function selectors, and ENS names. A solo builder working on a wallet, dapp, or on-chain agent reaches for it to sanity-check user input and computed values before signing or submitting anything. It ships as a pypi package run via uvx over stdio.
