WHAT IT DOES

What megaeth_unsubscribe does on Chain Debugger MCP Server

WHY IT NEEDS A POLICY

Why megaeth_unsubscribe needs a policy

Based on the naming pattern and the presence of a sibling 'megaeth_subscribe' tool, this tool likely cancels or removes an active blockchain event subscription. Canceling a subscription is an external operation with side effects (stopping data flow), placing it in Execute. The description is empty, so confidence is reduced.

From the tool's definition Tool name 'megaeth_unsubscribe' and empty description; sibling tool 'megaeth_subscribe' exists, implying this cancels an active subscription or event stream.
