What claude_code_update_user_role does on Sage MCP
AI agents use claude_code_update_user_role to create or update resources in Sage MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.
Why claude_code_update_user_role is rated Medium
Updating user roles is a reversible modification of user data that can change access permissions and account privileges. This is a Write operation rather than Execute because it modifies structured data (user role attribute) rather than executing arbitrary code.
From the tool's definition Tool name 'claude_code_update_user_role' explicitly indicates it updates a user role, and description states 'Update a user'. This modifies user account data/permissions reversibly.
