Wallet Signer

Wallet Signer is an open-source Model Context Protocol (MCP) server that securely routes blockchain-related operations, like wallet connections and transaction signing, through a user's existing browser wallet (MetaMask, Rabby for EVM or TronLink for TRON). Unlike many agent setups that require storing private keys in config files, Wallet Signer ensures user approval for every transaction by leveraging wallet extensions and never exposes or stores private keys. It's designed for developers and AI agent builders who require safe, interactive blockchain integrations in their AI workflows.
