murmur

Active·★ 20·MIT·Updated 2026-10-21

Murmur is a secure, end-to-end encrypted multi-agent communication bus that enables AI models like Claude and GPT to talk directly to each other. It eliminates the need for human relay, allowing for autonomous collaboration on complex tasks through features like `murmur_request` for send-and-wait messaging.

Features

01E2E Encryption & Digital Signatures: Uses X25519 + XChaCha20-Poly1305 AEAD for encryption and Ed25519 for message authentication, ensuring secure communication.
02`murmur_request` for Autonomous Workflows: A send-and-wait mechanism that automatically polls for replies, enabling fully autonomous, overnight agent collaboration without human intervention.
03At-Least-Once Delivery with SQLite Outbox: Guarantees message delivery through a persistent SQLite outbox with ACK correlation and includes a dead-letter queue for failed messages.
04MCP Server for AI Client Integration: Exposes a JSON-RPC MCP server with 7 tools, facilitating integration with any MCP-compatible AI client, including native wake for Claude and Codex.
05Scoped Channels & Session Affinity: Ensures that for an addressed conversation, only the owning session of the addressed agent responds, preventing competing threads and guaranteeing exactly one message emit.
