MCP Memory Server: What It Is & How to Choose (2026)
Originally published on m-i-n-d.ai . I write and maintain MIND, an MCP memory server — this piece tries to be straight about where MIND fits and where it doesn't. What Is an MCP Memory Server? The definition, the architecture, how to choose one, and an honest comparison of every option — including the GitHub repos that outrank us on this term today.

MIND is an MCP memory server maintained by Anthony Conti. It enables AI agents to store and retrieve memories, such as facts, preferences and past conversations, so that knowledge learned in one session persists for future use. MCP is an open standard for connecting AI applications to external tools and data. MCP memory servers offer a standard interface for agents to call as tools, regardless of the underlying retrieval technique.
They consist of three MCP primitives: tools (store_memory, search_memory), resources (read-only URI-addressable context), and transport (local stdio or remote HTTP). When choosing an MCP memory server, one must consider factors like storage (local file or real storage), transport (local-only or remote), self-hosting or cloud hosting, scope (single agent or shared memory), and whether the server offers additional products on top of memory.
The six real, maintained options discussed are MIND, Mem0 (via coleam00/mcp-mem0 and mem0), Letta, Zep (now cloud-only), and JamesANZ/memory-mcp.
