summarize_video · MCP Server MCP: Risk & Policy

WHAT IT DOES

What summarize_video does on MCP Server

AI agents invoke summarize_video to trigger actions in MCP 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 summarize_video needs a policy

This tool triggers an external summarization process, which constitutes executing an external operation. It is not a simple read (it initiates processing), nor does it write/modify user data directly. It calls an external endpoint that performs computation on a video resource, fitting the Execute category.

From the tool's definition 'Initiates video summarization by calling the /summarize endpoint' — triggers an external operation (API call to /summarize endpoint)

summarize_video Rate-limited

summarize_video stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
