Mem Os
Local-first persistent memory: store durable facts once and recall them in any session. Portable Agent Plugins v1 package (mcp.json + skills/): the @mem-os/sdk MCP server (pinned 1.6.26) over npx stdio, plus the mem-os-memory skill covering when to store and when to recall. All data stays in a local SQLite database under the user home directory; no cloud, no telemetry, no API keys. Server cwd is ${PLUGIN_DATA} so nothing is written into the install tree. Needs Node.js and npm on PATH.
How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install mem-os - Said no? Turn it on later:
hermes plugins enable mem-os - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
