WHAT IT DOES

What fizzy_create_comment does on Fizzy MCP Server

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

WHY IT NEEDS A POLICY

Why fizzy_create_comment needs a policy

Creating a comment is a write operation that adds data to a card. The severity is low because comments are typically non-critical metadata in task management systems, have minimal blast radius, and can be deleted. This is less severe than destructive operations (delete_comment, delete_card) or financial operations, making it a standard Write classification.

From the tool's definition Tool name 'fizzy_create_comment' and description 'Add a comment to a Fizzy card' indicate creation of new data (a comment). The action is reversible via fizzy_delete_comment (evidenced by sibling tools).
