About
Ethereum Transaction Builder is an MCP server that constructs and signs Ethereum transactions: EIP-1559 fee fields, gas estimation, RLP encoding, and ERC-20 token transfers. A solo builder making a wallet, bot, or on-chain agent reaches for it to assemble correctly-formed, signed transactions without hand-rolling the encoding. It ships as a pypi package run via uvx over stdio.
