Three ways to build
Cartridge, Layer 2 app or MCP server. Pick the surface first, they are not interchangeable.
Your first cartridge
Open the app, connect your coding agent, paste two prompts. Your cartridge runs inside Mnemosyne OS the same afternoon.
Connect Claude to Mnemosyne OS (MCP)
Give Claude, Cursor, Hermes or any MCP agent access to your local memory. Thirty seconds of config, zero cloud.
Connect your coding agent's memory
Point a vault at what Claude Code, Cursor, Aider or Continue writes down, from version 1.4.3.
Share your app
You do not need the store to hand someone your cartridge. A public repo link installs straight into Mnemosyne OS.
Support the project
Star the repo, post about it, join the Discord. Mnemosyne OS travels by word of mouth.
