There are now dozens of MCP memory servers. I've tried most of them. They almost all solve the same problem: your AI forgets everything between sessions, so you need something to make it remember.
That problem is basically solved. Pick any of the popular options — mem0, Basic Memory, claude-mem, MemPalace — and your Claude Code or Cursor session will remember what happened last time.
But there's a different problem that none of them solve, and it's the one that actually matters if you work on a team: your AI remembers your context, but your teammate's AI doesn't.
Two engineers on the same project. Two separate AI brains. Each one learning the codebase independently. Every architecture decision, every convention, every "we tried X and it didn't work because Y" — trapped in individual sessions that never talk to each other.
I've been building Context Cloud specifically around this problem. This is an honest comparison of where things stand.
