AI agents lose all memory and preferences between sessions with no portable layer that works across runtimes

AI agents lose all memory and preferences when a session ends, and the tools that do offer memory (Mem0, Zep, Letta, LangMem) each require their own SDK integration, so memory does not follow you across runtimes. This MCP server installs once and surfaces as a standard tool call that any MCP-compatible agent can read and write against, with no per-runtime wiring. Monetized as a hosted managed tier above an open core, where the premium layer provides larger memory stores, encryption at rest, team sharing, and redaction controls.
