WHAT IT DOES

What setup_authentication does on MCP Software Engineer

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

WHY IT NEEDS A POLICY

Why setup_authentication needs a policy

This tool creates or modifies authentication systems, which is a reversible Write operation. While authentication setup is security-critical and has high blast radius (misconfiguration could expose systems), the action itself creates/configures data structures rather than executing arbitrary code (Execute) or deleting data (Destructive).

From the tool's definition Tool name 'setup_authentication' and description 'Setup authentication system (JWT, OAuth, etc.)' indicate creation and configuration of authentication infrastructure.
