Memento Protocol
Dashboard →Your agent forgets everything. Fix that.
Memory that works like memory — not a log file. Store what matters, recall by meaning, skip the rest. Free tier, no credit card.

Next step: clone the repo and connect it to Claude Desktop, Claude Code, or any MCP client. The README walks you through it in under 5 minutes.
Stay in the loop
Early access updates, new features, and the occasional deep dive. No spam.
Free Tier (Beta)
Every signup starts free — no trial expiration, no surprise bills. 100 memories, 20 active items, semantic search included.
| Resource | Free | Full Coming soon |
|---|---|---|
| Stored memories | 100 | TBD |
| Working memory items | 20 active | TBD |
| Workspaces | 1 | TBD |
| Semantic search | Included | TBD |
| Consolidation | Included | TBD |
| Identity crystals | Included | TBD |
| Dashboard | Included | TBD |
| Hooks | Included | TBD |
Archived items don't count toward the item limit. All features are available on the free tier — semantic search, consolidation, identity crystals, hooks, the dashboard. Limits are just on volume.
The memento_health tool shows your current usage and remaining quota. When you hit a limit, the API returns a clear quota_exceeded error with your current count and the limit.
