Maindex Smart Memory Service

A straightforward memory layer that lets Claude keep, recall, update, and forget information across conversations. It connects via streamable HTTP and gives you four core operations: store new facts, retrieve what's been saved, modify existing entries, and delete what's no longer relevant. Useful when you need session continuity without building your own persistence layer. Maindex provides the backend infrastructure with revision history, typed relationships, and a knowledge graph you can inspect through their dashboard. Works across multiple AI clients through MCP, so the same memory follows you whether you're in Claude, Cursor, or ChatGPT. The free tier gets you started, and collections can be locked behind passphrases if you're storing sensitive context.
