kairos_disable · OpenClaude MCP Server MCP: Risk & Policy

WHAT IT DOES

What kairos_disable does on OpenClaude MCP Server

AI agents use kairos_disable to create or update resources in OpenClaude MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OpenClaude MCP Server environment.

WHY IT NEEDS A POLICY

Why kairos_disable needs a policy

Disabling KAIROS modifies the configuration/state of a session by turning off a feature. Since the sibling tool 'kairos_enable' exists to reverse this action, the operation is reversible and falls under Write rather than Destructive.

From the tool's definition 'Disable KAIROS on a session' — deactivates a feature/mode on an existing session, which is a reversible state change (can be re-enabled via kairos_enable sibling tool).
