Non-custodial EVM wallet MCP — routes transactions to browser wallets (MetaMask, etc.) for signing. Private keys never leave the browser; every action requires explicit user approval via EIP-6963.

Overview

Direct install

Run the underlying MCP server directly — without Agent-CoreX routing.

npx -y mcp-wallet-signer
