## Nauti's Take

The idea is solid and the pain point is real – anyone working seriously across multiple agent clients knows the key-management chaos. That said, Danube solves a security problem by creating a new one: all credentials now sit with a single, unproven vendor. That is not a dealbreaker, but it is the first question any reasonable user will ask. The business model – tool monetization via a central marketplace – follows App Store logic for agents, which conceptually makes sense. The real question is whether a critical mass of tool developers shows up before the major players (Anthropic, OpenAI, Microsoft) solve this themselves.
