create_level · Ice Puzzle MCP: Risk & Policy

WHAT IT DOES

What create_level does on Ice Puzzle

AI agents use create_level 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 create_level needs a policy

This is a Write operation because it creates new data (a level object) with reversible side effects—the created level can be modified, deleted, or discarded without permanent consequence. It does not execute arbitrary code, trigger external systems, or have financial impact. The 'empty' nature and game design context indicate low severity: creating a blank level carries minimal blast radius if called by an AI agent.

From the tool's definition Tool is described as creating 'a new empty ice puzzle level', which generates new data in a game design context.

Verdict

create_level Rate-limited

create_level stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
