# Limitations

## Archive-only data source

MCP runs queries only against [archive storage](https://coralogix.com/docs/user-guides/account-management/tco-optimizer.md#low-compliance). It does not support environments that use only high-tier storage (Frequent Search).

This can lead to the following scenarios:

* Time-based log queries, such as show logs in last 10 minutes, return zero results even though you see logs in Frequent Search.

* Any natural language query that targets recent logs appears empty because MCP cannot access non-archived data.

To avoid these issues, configure archive storage for your account and ensure relevant logs are being archived. For setup steps, see [Connect S3 archive](https://coralogix.com/docs/user-guides/data-flow/s3-archive/connect-s3-archive.md).
