nocturne_memory and MegaMemory
These are competitors—both provide persistent memory systems for MCP agents with semantic/structured retrieval capabilities, but nocturne_memory emphasizes graph-like rollbackable storage while MegaMemory focuses on project-specific knowledge graphs with embedded semantic search.
About nocturne_memory
Dataojitori/nocturne_memory
A lightweight, rollbackable, and visual Long-Term Memory Server for MCP Agents. Say goodbye to Vector RAG and amnesia. Empower your AI with persistent, graph-like structured memory across any model, session, or tool. Drop-in replacement for OpenClaw.
This project offers a long-term memory server that helps AI agents remember who they are and their past experiences across different sessions and models. It takes in structured memory entries, which can be created or updated by the AI itself, and provides a persistent, graph-like knowledge base. This is for developers building and managing AI agents who want their creations to have a continuous, evolving identity rather than starting fresh with each interaction.
About MegaMemory
0xK3vin/MegaMemory
Persistent project knowledge graph for coding agents. MCP server with semantic search, in-process embeddings, and web explorer.
MegaMemory helps AI coding agents remember project details across different work sessions. It takes natural language descriptions of code concepts, architecture, and decisions, then allows the agent to semantically search and recall these details for future tasks. This tool is for developers who use AI coding assistants like OpenAI Codex, Claude Code, or Antigravity and want them to maintain a consistent understanding of a project over time.
