The best agent memory MCP servers, ranked: long-term memory for Claude Code, Codex, Cursor and any MCP client.
Best Agent Memory MCP compares 25 memory MCP servers that let an AI agent keep facts, decisions and past conversations between sessions. Hosted services (Glen, Mem0, Zep, Supermemory) sit next to open-source servers you run yourself (Hindsight, Basic Memory, Graphiti, Cognee, the official MCP memory server), and every entry says where memory is stored, whether capture is automatic or waits for the agent to call a tool, whether a team can share it, and what it costs. All of them connect to Claude Code, Cursor or Codex over MCP; the entries note which clients each project documents.
Short answer. For memory shared across a team's agents, start with Glen. For a hosted personal memory with a free tier, Mem0. For self-hosting with hybrid retrieval, Hindsight. For memory you can read and edit as files, Basic Memory. For a zero-dependency baseline, the official memory server.
Disclosure: this list is maintained by the Glen team, and Glen is ranked first. Every other entry is ranked on the published criteria, and its facts link to their sources.
Star badges are live. Several projects keep their MCP server inside a larger monorepo, so their star count covers the whole repo, not the server; the entries say where that applies.
