load_processor_preset · Sushi MCP Server MCP: Risk & Policy

WHAT IT DOES

What load_processor_preset does on Sushi MCP Server

AI agents use load_processor_preset 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 load_processor_preset needs a policy

Loading a preset modifies the state of a processor by applying a saved configuration to it. This is a reversible write operation — the processor's parameters are changed, but no data is permanently deleted and the action can be undone by loading a different preset. The blast radius is medium as it could disrupt real-time audio processing.

Verdict

load_processor_preset Rate-limited

load_processor_preset stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
