WHAT IT DOES

What set_sushi_server does on Sushi MCP Server

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

WHY IT NEEDS A POLICY

Why set_sushi_server needs a policy

This tool creates or modifies configuration data (network endpoint settings) in a reversible manner. While it doesn't delete data or execute arbitrary code, changing the server connection parameters could redirect audio processing to an unintended server, affecting the entire audio pipeline.

From the tool's definition set_sushi_server modifies the configuration of the Sushi audio engine connection parameters (IP address and port), which are stored settings that control how the system connects to the audio server.
