Route EVM transactions to browser wallets (MetaMask, etc.) for signing via EIP-6963

Your private keys never leave your browser. Every transaction requires explicit user approval in your wallet. Most blockchain MCPs require you to paste a private key into a config file — giving the AI agent full, unsupervised access to your funds. MCP Wallet Signer takes a different approach: it routes every transaction to your actual browser wallet — EVM wallets (MetaMask, Rabby, …) via…

About

Your private keys never leave your browser. Every transaction requires explicit user approval in your wallet. Most blockchain MCPs require you to paste a private key into a config file — giving the AI agent full, unsupervised access to your funds.
