# @three-ws/naming-mcp > Resolve Solana .sol names and check *.threews.sol agent-identity availability from any AI agent. sns_resolve maps a .sol name to its owner wallet, sns_reverse maps a wallet to its primary name, and threews_availability checks whether a three.ws agent handle is free to claim. No key, no signer, no payment. @three-ws/naming-mcp is a Model Context Protocol server from three.ws.
