WHAT IT DOES

What update_brand_profile does on AI-Canvas MCP Server

AI agents use update_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 update_brand_profile needs a policy

This is a Write operation because it creates or modifies data reversibly. The 'update' action changes brand profile metadata that governs design outputs. Severity is high because a compromised brand profile could affect multiple design documents, mockups, and exported materials organization-wide. While reversible (not Destructive), the blast radius is significant if an AI agent makes unauthorized brand changes.

From the tool's definition Tool description states 'Update a global brand profile: name, description, version, tags, or constraints' — this modifies brand data that is likely used across multiple design documents and outputs.

update_brand_profile Rate-limited
