Memory MCP Server

The Memory MCP Server gives your AI a persistent, knowledge-graph-based memory — facts, preferences, and relationships you tell it are stored and recalled across conversations.

For example, once you say "I'm building a directory site called mcpradars," the AI can remember that context in a new conversation later. This is an official MCP reference implementation.
