get_user
AI agents call get_user to retrieve information from Mattcoatsworth Canva without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix combined with read-only sibling tools strongly suggests this retrieves user data without modification. No evidence of side effects, data destruction, code execution, or financial operations. Low severity because user retrieval typically has limited blast radius unless it exposes sensitive personal information; confidence is moderate due to the empty description.
From the tool's definition Tool name 'get_user' indicates a retrieval operation; sibling tools on this server include 'get_asset', 'get_brand', 'get_design', 'list_assets', 'list_brands', 'list_designs', and 'list_users', all read-only operations.
