Add Persistent Memory To Claude Code With Mem0 (5-Minute Setup)

Mem0’s guide describes adding a cloud-hosted persistent memory layer to Claude Code through its Model Context Protocol integration, positioning it as a complement to Claude Code’s built-in Auto Memory feature, which stores a limited project-specific MEMORY.md file without semantic retrieval or cross-tool sharing. The proposed Mem0 Platform MCP setup works with both the Claude Code CLI and Claude Cowork desktop app, either through a recommended plugin marketplace installation or manual MCP configuration using a Mem0 API key, while an alternative OpenMemory MCP option offers local, self-hosted storage. The full plugin provides memory tools, lifecycle hooks that capture or retrieve context at session events, and SDK guidance, enabling Claude to semantically search, add, update, and delete memories across users, agents, applications, and sessions. The guide argues that this can reduce repeated project explanation, preserve technical decisions and conventions across repositories and tools, and support teams sharing context, while noting that users can combine Mem0 with CLAUDE.md and Auto Memory. It also outlines available free-tier limits, debugging options, compliance and self-hosting capabilities, and the need to restart Claude Code after plugin updates to refresh the MCP connection.
