Is memory the same as RAG?

Related but not identical. Memory MCPs store agent-writable facts; RAG usually retrieves from your docs corpus. Many setups use both.

Where is data stored?

Depends on the server — local files, a graph store, or a hosted backend. Read the server page before putting secrets in memory.
