Researchers have developed Minimum-Necessary Communication (MNC), a protocol designed to enhance privacy in multi-agent large language model (LLM) systems. MNC addresses the issue of LLMs potentially exposing sensitive information through internal messages and data, even when their external outputs seem harmless. The protocol allows for task-sufficient disclosure of information, bound by explicit scopes for recipients, purpose, forwarding, and lifetime, with a reference monitor enforcing these boundaries. Experiments demonstrate that MNC can maintain authorized communication while preventing unauthorized forwarding, logging, or storage, even when mediated disclosures propagate through subsequent agent actions.
