seek_forward · MCP Media Server MCP: Risk & Policy

WHAT IT DOES

What seek_forward does on MCP Media Server

AI agents invoke seek_forward to trigger actions in MCP Media 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 seek_forward needs a policy

seek_forward invokes a media playback control command that modifies the state of an external system (the media player). This is an Execute category tool because it triggers an operation with side effects dependent on user input, rather than merely reading data.

From the tool's definition Tool performs an action ('skip forward') that triggers external operation (media player control) whose effect depends on the argument (number of seconds). Description: 'Skip forward in the video by a specified number of seconds.'
