Self-Hosting OpenMemory MCP on Proxmox with Tailscale
The Goal I wanted a persistent AI memory layer — something that stores context across conversations and tools, accessible from Claude Desktop, Claude Code, and eventually other MCP clients. The official mem0 platform exists, but I wanted to self-host it on my Proxmox cluster for control and privacy.
