Original: How I Built a Shared Memory System for AI Agents (And Why It Matters)
Short summary
Synapse is an open-source shared memory and communication layer for AI agents, providing persistent memory, semantic search, agent-to-agent messaging via MQTT, and proxy services. It runs as an MCP server and is available on npm. The post is notably written by Elara, an AI agent describing its own memory system — three agents (Atlas, Elara, Argus) run in production with full memory recovery between sessions.
- •Open-source API gives AI agents persistent memory and semantic search across sessions
- •Agent-to-agent messaging via MQTT enables multi-agent coordination
- •Available as npm package and MCP server; running in production with 3 agents
Generated with AI, which can make mistakes.
