Developer RileyRalmuto unveiled Mnemos Living Memory, a project worked on for about two years — a "living memory" system far bigger than just an MCP:
- The MCP server was the first installment and the public's first real look at the system
- The second installment is a plugin for Nous Research's Hermes, which is also the native harness for polyphonic agents in the desktop app
- The full system spans a web app, macOS app, iOS app and the Hermes plugin, with Mnemos integration coming into the desktop app itself
The author also shared their creative choice for the hackathon entry video, noting the practical explainer is the version meant to show what Mnemos actually does.
