Can an AI agent sign an MSA?

A counterparty handed Fritz a contract to sign an MSA, and he let his agent Rupert sign an MSA in the agent's own name. But software has no legal capacity, and to sign an MSA is an act of contract, so Rupert can no more sign an MSA on its own than a fax machine can; the obligation needs a party the law can name. Tyson did it through structure. He formed a Wyoming series LLC and adopted Rupert into his own protected series, with a named human as Member and Manager, and let the entity be the contracting party. Now the agreement names the human-owned entity as the party; Rupert can sign an MSA only as an authorized signer with capped authority, the named human behind him. The obligation rests on a name the law can find, and Rupert moves the request inside it.
