What demo_vid_generate does on Demo Vid
AI agents invoke demo_vid_generate to trigger actions in Demo Vid. 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 demo_vid_generate is rated High
The tool name strongly implies it triggers the actual video generation pipeline, which would involve running Playwright (browser automation), TTS (text-to-speech synthesis), and FFmpeg (media processing) — all external process executions with significant resource usage.
From the tool's definition Tool name 'demo_vid_generate' on a server described as a 'Fleet demo video pipeline — narrated walkthroughs via Playwright, TTS, and FFmpeg'; sibling tools include script drafting, validation, and refinement steps suggesting this is the execution/generation…

The rule that runs demo_vid_generate safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Demo Vid, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For demo_vid_generate, this is the rule to start with:
demo_vid_generate 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Demo Vid, apply this rule, and every demo_vid_generate call is checked against it from then on.
