WHAT IT DOES

What strudel_transform_pattern does on Strudel MCP Server

AI agents invoke strudel_transform_pattern to trigger actions in Strudel MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why strudel_transform_pattern needs a policy

This tool executes code-like operations (pattern transformations) whose side effects depend on the arguments—transformed patterns will alter the audio output. It is not merely reading data (would be Read), nor is it creating new patterns from scratch (would be Write). It transforms existing patterns, which is a form of code execution. It does not destroy data (not Destructive) or move money (not Financial).

From the tool's definition Tool applies transformations to patterns in a live coding music system. The verb 'apply' combined with 'transformations' to 'existing patterns' indicates the tool executes operations that modify state and produce effects dependent on the transformation…
