WHAT IT DOES

What save_local_draft does on Ice Puzzle

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

WHY IT NEEDS A POLICY

Why save_local_draft needs a policy

This tool creates or stores data (a draft snapshot) in local memory, which is reversible—drafts can be overwritten, deleted, or replaced later. It does not execute arbitrary code, delete data, or move money. It is Write rather than Read because it modifies persistent state rather than merely querying it.

From the tool's definition save_local_draft saves a snapshot of the current draft, which modifies the state of the local MCP memory by persisting draft data.
