WHAT IT DOES

What setup_routing does on MCP Software Engineer

AI agents use setup_routing 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

This tool modifies application routing configuration, which is a Write operation—it creates or updates configuration that determines how requests are directed in an application. While routing misconfigurations could have high operational impact, the action itself is reversible (routing can be reconfigured or reverted).
