Add captions to a short video (up to 5 minutes). Ask the user for aspect_ratio and caption_style if they're not given. If the user says 'just pick,' default to aspect_ratio '9:16' and caption_style 'minimalist'. Jobs take 3-8 minutes; Vugola will email the user when done, and the agent can check ...

AI agents use caption_video to create or modify resources in Vugola. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call caption_video repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Vugola.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Add captions to a short video (up to 5 minutes). Ask the user for aspect_ratio and caption_style if they're not given. If the user says 'just pick,' default to aspect_ratio '9:16' and caption_style 'minimalist'. Jobs take 3-8 minutes; Vugola will email the user when done, and the agent can check status via get_clip_status.. It is categorised as a Write tool in the Vugola MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Vugola MCP server in PolicyLayer and add a rule for caption_video: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Vugola. Nothing to install.
caption_video is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the caption_video rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for caption_video. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
caption_video is provided by the Vugola MCP server (vugola-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
