What each does
MemPalace: Free, open-source long-term memory system for AI assistants, with an MCP server so agents can save and recall what they learned.
Everything (reference): Reference test server from the MCP maintainers that exercises every protocol feature (tools, prompts, resources). Useful for checking a client, not for daily work.
