update_video · Reka Vision MCP Server MCP: Risk & Policy

WHAT IT DOES

What update_video does on Reka Vision MCP Server

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

WHY IT NEEDS A POLICY

Why update_video needs a policy

The 'update_' prefix conventionally indicates a Write operation that modifies existing data. Without an explicit description, we infer from context: the server manages video data, and update_video likely modifies video properties, metadata, or associated information (tags, groups, etc.) without deleting it. This is reversible (opposite of Destructive) and does not execute external code (unlike Execute).

From the tool's definition Tool name is 'update_video' which indicates modification of video data. The description is empty, but based on the sibling tools on this server (upload, index, delete, get operations on videos), this tool modifies existing video records or metadata reversibly.
