What data does the server store and where?

To Do items are stored in memory only. They are not persisted to disk; all data is lost when the server process stops.

Does the server support authentication or encryption?

The server communicates over stdio (standard input/output), making it suitable for local integration with MCP clients that spawn subprocesses.
