mcp-memory-service and MegaMemory
These are competitors offering overlapping persistent memory solutions for AI agents, though A targets broader agent frameworks while B specializes in coding-specific use cases with embedded semantic search.
About mcp-memory-service
doobidoo/mcp-memory-service
Open-source persistent memory for AI agent pipelines (LangGraph, CrewAI, AutoGen) and Claude. REST API + knowledge graph + autonomous consolidation.
This service provides a shared, persistent memory for AI agents, allowing them to retain information and learn across different tasks and sessions. It takes in decisions and facts from various agents, organizing them into a knowledge graph. The output is fast, relevant context that helps agents make better decisions, suitable for anyone building or managing multi-agent AI systems, like AI solution architects or AI product managers.
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.
