Hermes memory: a provider swap, not a rebuild
Hermes treats memory as a provider: a component you select in configuration. That design makes the upgrade a config line instead of a migration project.

How Hermes handles memory today
Hermes ships with a local memory provider, so recall depends on what is stored on the machine running the agent. Move the agent, rebuild the container, or clear state, and the memory goes with it.
The provider is configurable, and the published hermes-memoryrouter package registers MemoryRouter as a provider with the current Hermes release.
What Hermes Agent forgets
Local state is fast until it is gone.
- Everything on a machine change or container rebuild.
- Recall quality as the local store grows, because local providers rarely do relevance ranking well.
- Cross-runtime continuity with your editors and CLIs.
- History for long runs that exceed what the local store retains.
The fix with MemoryRouter
Install the provider package, register it, and switch the active memory provider. Hermes keeps working the same way, with a durable store behind it.
- 1
Install and register the provider
Install and activate
pip install hermes-memoryrouter hermes-memoryrouter install hermes config set memory.provider memoryrouter - 2
Provide the key
Export MEMORYROUTER_API_KEY or place a memoryrouter.key file in your Hermes home with mode 0600. The package reads either.

Verify recall
Run a task that states a unique fact, then start a fresh session and ask for it. The provider answers from the vault rather than local state.
