AI agents call get-user-current-permissions-document to retrieve information from Mcp Dev without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves current user permission information for a document in Umbraco CMS. It performs a read-only operation that retrieves data without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal—an AI agent could only view permissions it might not normally see, which is a low-severity information disclosure risk.
From the tool's definition Tool name 'get-user-current-permissions-document' and description 'Gets the current user' indicate retrieval of user permission data with no modification or side effects.
