create-user · HR Solx MCP Server MCP: Risk & Policy

WHAT IT DOES

What create-user does on HR Solx MCP Server

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

WHY IT NEEDS A POLICY

Why create-user needs a policy

Creating user accounts is a reversible write operation that modifies system state by adding new data. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. Severity is medium due to the potential for unauthorized user creation affecting access control and system integrity, but the operation itself is reversible through standard user deletion/deactivation procedures.

From the tool's definition Tool name is 'create-user' and description states 'Create user'. The server description confirms it enables 'creating or listing user accounts'. This creates new records in the HR system.
