## Nauti's Take

MCP arriving in enterprise architectures with clean account separation is real progress: teams keep ownership of their data while agents still get one consistent way in. The risk lies in complexity, because every extra cross-account permission is a potential gap. Platform teams in larger AWS estates should evaluate the pattern; smaller companies are usually better off with a single account.
