That's a great point! And also works really well for shared context between claude instances, for example, we use that for our business model in the company, all business rules and model is stored as memories in a central redis that the mcp connects to. The way that memories are stored are specific to a folder or global (similar to CLAUDE.md home directiory), but with this approach you can have an external redis where multiple claudes read and write into as a shared almost hive like memory.
