unfreeze_baseling · Baselings MCP: Risk & Policy

WHAT IT DOES

What unfreeze_baseling does on Baselings

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

WHY IT NEEDS A POLICY

Why unfreeze_baseling needs a policy

Unfreezing a baseling changes its state from frozen to active, which is a reversible write operation on-chain. While it interacts with a blockchain (making it potentially irreversible in some sense), it is restoring/activating an asset rather than destroying or deleting it. It does not directly move funds or execute arbitrary code.

From the tool's definition 'Wake baseling from cryo' — this reverses a frozen/cryo state, modifying the state of an in-game asset on the Base chain

Verdict

unfreeze_baseling Rate-limited

unfreeze_baseling 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.
