kairos_enable · OpenClaude MCP Server MCP: Risk & Policy

WHAT IT DOES

What kairos_enable does on OpenClaude MCP Server

AI agents invoke kairos_enable to trigger actions in OpenClaude MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why kairos_enable needs a policy

This tool triggers an external daemon process (the KAIROS autoDream memory consolidation daemon) on a session, which constitutes executing/starting an ongoing background operation. It is not a simple read or write — it activates a running process with side effects (memory consolidation).
