Why this server?
Connectors capture tacit fragments from workplace systems and deliver whisper prompts to experts in Slack, so they can confirm their practice in context.
AlicenseAqualityAmaintenanceMetis gives AI agents expert know-how that named reviewers have approved, and only where its recorded conditions match the situation. High-risk situations go to a person. When an agent sees practice depart from procedure, it can send the expert one short question. Every retrieval is recorded on a hash-linked evidence chain.610359 PyPI2Apache 2.0Why this server?
