WHAT IT DOES

What create_objective does on Hammerspace Storage Management MCP Server

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

WHY IT NEEDS A POLICY

Why create_objective needs a policy

Creating an objective in a storage management system is a write operation that modifies configuration state but is reversible (objectives can be updated or deleted by other tools). It does not directly execute arbitrary commands, delete data irreversibly, or move funds.

From the tool's definition Tool description indicates 'Create an objective' which is a reversible write operation. Context shows this is part of a storage management system where objectives likely define policies (tier management, tagging rules, ingestion workflows).
