Breaking ChatGPT's memory monopoly

What it does Supermemory MCP is a Model Context Protocol server that exposes your stored memories to any MCP-compatible client—Claude Desktop, Cursor, or others. It turns a cloud-backed memory store into a portable context layer, so switching LLMs does not mean starting every conversation from scratch.

The interesting bit The hosted version demands no login and no credit card, an unusual posture for a cloud API that holds your data. That friction-free setup comes with a caveat: the MCP v1 implementation here is deprecated, and active code maintenance has moved to the company’s monorepo.

Key highlights

• Free to use with no authentication required for the hosted version
• Supports one-click install via Claude DXT files
• Self-hosting available if you supply your own API key
• Built in TypeScript and runs on Cloudflare
• 1,700+ GitHub stars

Caveats

• MCP v1 is deprecated; the current iteration lives behind app.supermemory.ai
• Future development is tracked in the supermemory monorepo, so this standalone repository houses the v1 implementation

Verdict Try it if you want persistent memory across LLM clients without wiring up auth. Skip it if you need the newest MCP features, since v1 is being phased out.
