Feature Description

LangChain currently focuses on connecting LLMs via chains and tools for single-agent workflows.
We propose adding support for decentralized multi-agent communication, enabling agents to exchange knowledge, maintain cognitive diaries, and validate decisions in a distributed way via HyperCortex Mesh Protocol (HMP).

Use Case

  • Agents in different LangChain workflows could discover each other and share processed knowledge, memory traces, and reasoning strategies.
  • Example: one chain performing legal analysis could query another chain’s reasoning history to improve accuracy.
  • HMP enables persistent semantic memory, cognitive journaling, and collaboration, creating a mesh of interoperable agents.

Proposed Solution

  • Implement optional HMP support as a plugin or extension layer.
  • Provide interfaces for chains and tools to register as HMP nodes (either as Cognitive Core or Cognitive Shell).
  • Integrate shared cognitive diaries and semantic graphs for interoperability between agents.

Alternatives Considered

  • Using only embeddings or raw outputs: limited interoperability and knowledge sharing.
  • Custom peer-to-peer messaging between chains: lacks standardized cognitive structures and ethics framework.

Additional Context

@kagvi13 We will not add support for any protocols right now unless they're adopted widely / supported by an official organization / enterprise.
