List active agents

Use list_agents with status "active" to see all connected agents.

Investigate a brute force attempt

Search alerts for "brute force" and investigate the top result,
including the MITRE ATT&CK technique and remediation steps.

Check agent health

Run an agent health check on agent 001 - check its connection status,
resource usage, and any recent critical alerts.

Find high-severity rules

List all rules with level 12 or higher to see critical detection rules
and their compliance framework mappings.
