WHAT IT DOES

What create_classification_rule does on Claude MCP Server Integration

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

WHY IT NEEDS A POLICY

Why create_classification_rule needs a policy

This tool creates new classification rules, which modifies system state by adding new rule definitions. This is reversible (rules can be deleted or modified), so it falls under Write rather than Destructive. The severity is medium because misconfigured classification rules could misdirect workflows or cause operational issues, but the blast radius is limited to the classification system itself.

From the tool's definition Tool name 'create_classification_rule' and description '分類ルールを作成します' (creates a classification rule) indicate data creation/modification functionality. The verb 'create' combined with 'rule' suggests writing new configuration or rule data to the system.
