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
- Status: Gated preview — no general-availability date announced yet
- Access: Sign up free to create an API key
Free tier limits
| Limit | Value |
|---|---|
| Memories held | 1,000 at once |
| Memories created | 1,000 per calendar month |
| Retention | 90 days |
| API rate limit | Shared (not per-plan yet) |
These are two separate limits, not one. You can hold up to 1,000 memories at once, and create up to 1,000 new memories per calendar month.
Billing is simulated, and upgrading is not self-serve
Billing runs in Stripe test mode during the preview. No real charges will occur, and invoices and payment history are simulated.
There is no self-serve upgrade. On the Billing page, the Pro plan shows a Contact Sales link that opens an email to [email protected] — there is no checkout button to click. Enterprise works the same way. We have not announced a date for self-serve upgrade.
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
- Bulk operations — Multi-select delete and bulk actions in the dashboard are not available
Data expectations
Export important data regularly 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
These items are actively in development and may become available during the preview:
- Full account deletion with data cascade
- Rate limiting by plan tier
- MCP server stability improvements
