Known Limitations
Current limitations and expectations for the MemNexus gated preview.
This page documents what's in scope, what's not, and what to expect during the preview period.
Preview scope
- Duration: 4 weeks
- Users: 10-15 invited developers
- Access: Invite code required — no public signup
Free tier limits
| Limit | Value |
|---|---|
| Memories | 200 |
| Retention | 60 days |
| API rate limit | Shared (not per-plan yet) |
Quota enforcement is being finalized. You may temporarily exceed the 200-memory limit during the preview. This will be enforced before public launch.
Billing is simulated
Billing runs in Stripe test mode during the preview. No real charges will occur. Use the test card 4242 4242 4242 4242 to try the upgrade flow. Invoices and payment history are simulated.
MCP server
The MCP server is functional but under active development. You may encounter connection issues when using it with Claude Desktop, Cursor, or other MCP clients. If MCP isn't working for you, the CLI and SDK provide the same functionality.
Known MCP issues:
- Occasional connection drops requiring client restart
- Some tools may return incomplete error messages
- Configuration varies by AI client — check the integration guides for your specific platform
Not included in the preview
- Mobile-optimized experience — The dashboard works on mobile browsers but isn't optimized for small screens
- Enterprise features — No SSO directory sync, audit logs, or SLAs
- Rate limiting by plan — Rate limits are shared across all tiers during the preview
- Retention enforcement — The 60-day cleanup for free-tier memories is not yet active
- Bulk operations — Multi-select delete and bulk actions in the dashboard are not available
Data expectations
Data created during the preview may be reset before public launch. Do not store anything irreplaceable in MemNexus during the preview period. Export important data with mx memories list --format json --limit 10000 > backup.json.
Known issues
| Issue | Workaround |
|---|---|
| Dashboard may show stale data after creating memories via CLI | Refresh the page |
| Search relevance may vary for very short queries (1-2 words) | Use more descriptive queries |
| Account deletion is not yet fully implemented | Contact us directly if you need your account deleted |
What we're working on
