# knowledge_bases

> Knowledge bases (contract 1.14):

Knowledge bases (contract 1.14): each index your agents search, with its health score (freshness, ingestion, duplicates, retrieval quality), size, last refresh, searches per day, zero-result rate and the agents using it. Counts only; documents stay in your account.

**Role:** viewer and above (any person, AAL staff, machine key).

**Acts:** no. It only reads; nothing an AI agent calls through MCP approves, pays, or changes a limit.
