create_sequence · Media-Editor- MCP: Risk & Policy

WHAT IT DOES

What create_sequence does on Media-Editor-MCP

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

WHY IT NEEDS A POLICY

Why create_sequence needs a policy

The tool creates new sequences in a video editing context (CapCut or Adobe Premiere Pro), which constitutes data creation and project modification. This falls under Write rather than Execute because it is not running arbitrary code or triggering unpredictable external effects—it is performing a well-defined creation operation within the editing application.

From the tool's definition Tool name 'create_sequence' and description indicating it creates a new sequence with settings matched to media items. This is a creation operation that modifies the editing project state reversibly.

create_sequence Rate-limited

create_sequence 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.
