Builds an unsigned Solana transaction with the Vybe Solana API (see https://docs.vybenetwork.com) for a token swap, a token-account close, or an MEV withdrawal, and returns it as base64 for the user to review and sign in their own wallet. This tool never signs, submits, or broadcasts a transaction, never moves funds on its own, and never accepts private keys. Use query-vybe-api with /v4/trading/swap-quote first when the user only wants a price quote.
