Clairwave
Ocean acoustics: propagation models, bathymetry, sound speed, vessel noise, live AIS. Open.The vendor's description, from its MCP Registry listing.
Every public check ran and passed. Public audit: we connect as an AI client would, list the tools and check what they say. We do not run them. How we audit
- Does it work?
- YesConnected in 217 ms.
- Sign-up?
- None neededIt answered without any account or key.
- Can it change things?
- YesSome tools say they can change things. Your AI client should ask you first.
