WHAT IT DOES

What save_brand_profile does on AI-Canvas MCP Server

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

WHY IT NEEDS A POLICY

Why save_brand_profile needs a policy

The tool persists brand configuration data (colors, typography, spacing) to a global/shared repository, making it a Write operation. Severity is medium because misuse could corrupt or pollute the organization's reusable brand assets, affecting downstream design projects, but the changes are reversible (profiles can be updated or deleted).

From the tool's definition Tool description explicitly states 'Save a brand profile...to the global library' — this is a create/store operation that modifies shared library state.
