WHAT IT DOES

What fl_add_marker does on FL Studio MCP Server

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

RISK

Why fl_add_marker is rated Medium

This tool creates a new marker in the FL Studio arrangement, which is a reversible write operation. Markers are metadata artifacts in a DAW project that organize the timeline; adding them does not delete data, execute arbitrary code, or cause financial impact. A misused marker addition would have minimal blast radius—the user could simply delete the marker. This is a straightforward Write category action.

From the tool's definition Tool adds/creates a time marker at the current song position. The verb 'add' and action of creating a new marker indicates data modification.
