Q: What are Knowledge & Memory Model Context Protocol (MCP) servers?

Model Context Protocol (MCP) servers in the Knowledge & Memory category allow AI assistants (such as Claude Desktop, Cursor, Windsurf, and Cline) to connect directly to knowledge & memory tools, APIs, and databases without manual copy-pasting.

Persistent memory, note stores, and knowledge bases exposed over MCP, so agents can remember context across sessions and reason over your accumulated knowledge.
