AI and memory servers store what an agent learns, retrieve from vector indexes, or call other models. Note where embeddings are computed and where memories are stored before you connect one. 3575 published MCP servers match this ranking. The highest trust scores right now are Vitkilabs Anvil at 55, Agent Cowork Memory at 55, VelesDB Memory at 55. The order is the published trust score: registry record, license, maintenance, popularity, documentation, and security signals. Featured slots, when an editor sets them, are labeled and do not change the score. Best AI and memory MCP servers is not a paid placement.
