add_notes · Flai MCP: Risk & Policy

WHAT IT DOES

What add_notes does on Flai

AI agents use add_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 add_notes needs a policy

This tool creates or modifies notes within a music pattern in FL Studio. While reversible (notes can be deleted/edited afterward), it has write semantics. The severity is medium because misuse by an AI agent could produce unintended music compositions or overwrite creative work, but the impact is limited to a single pattern's note data and poses no financial, destructive system, or code-execution risk.

From the tool's definition Tool name 'add_notes' and description 'Add notes to a pattern without clearing existing notes' indicate creation/modification of music pattern data. The key phrase is 'add notes' which is a reversible write operation that modifies pattern state.

Verdict

add_notes Rate-limited

add_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.
