WHAT IT DOES

What create_global_ruleset does on OpenRemote MCP Server

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

WHY IT NEEDS A POLICY

Why create_global_ruleset needs a policy

This tool creates a new global ruleset, which is a Write operation. The severity is high because global rulesets apply across the entire OpenRemote instance, meaning a misconfigured or malicious ruleset could affect all realms, assets, and users system-wide. It is reversible (a sibling tool 'delete_global_ruleset' exists), so it does not qualify as Destructive.

From the tool's definition "Create a new global ruleset" - creates a new resource at global scope
