set_notes · Flai MCP: Risk & Policy

WHAT IT DOES

What set_notes does on Flai

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

WHY IT NEEDS A POLICY

Why set_notes needs a policy

This tool creates or modifies note data in FL Studio, which is reversible (notes can be edited, deleted, or undone within the DAW). It does not execute arbitrary code, delete data irreversibly, or move funds. The medium severity reflects that misuse could corrupt a music project, but changes are typically undoable in a DAW context and the blast radius is limited to the project state.

From the tool's definition Tool name 'set_notes' combined with sibling tools 'add_notes' and 'get_notes' pattern indicates data creation/modification. Server description states it 'write[s] notes' and 'manipulate[s]' FL Studio parameters.

Verdict

set_notes Rate-limited

set_notes 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.
