Bulk discovery

Muster can automatically discover agents you didn’t know about via:
  • Git scan — finds agent code patterns in your repositories
  • DNS query — detects LLM API calls from your infrastructure
  • Cost Explorer — spots unexpected LLM spend in AWS
  • n8n / Flowise / Dify connectors — lists all active workflows
Discovered agents appear in the Discovery Queue for your review before being added to the registry.
