Cognee

Knowledge-graph memory for Hermes, shared with Cognee's Claude Code, Codex and OpenClaw plugins: automatic recall, remember, forget, recaps and code search, on a local cognee server or Cognee Cloud.

Good to know before installing

Runs a local cognee server (uvicorn on 127.0.0.1:8011) and a session-close watcher in the background; each turn plus its tool calls and results (redacted, capped) go to that server and on to your configured LLM provider (OpenAI by default), or to Cognee Cloud / COGNEE_BASE_URL in remote mode; turns the server could not take are queued in ~/.cognee-plugin; the store lives in ~/.cognee, outside HERMES_HOME and shared across profiles and with Cognee's Claude Code, Codex and OpenClaw plugins; cognee sends anonymous telemetry unless TELEMETRY_DISABLED=1.

How to install

Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install cognee
Said no? Turn it on later:
hermes plugins enable cognee
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).
