Medium Risk

caption_video

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 ...

vugola-mcp Write Risk 2/5

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. Intercept'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.

What does the caption_video tool do? +

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.

How do I enforce a policy on caption_video? +

Add a rule in your Intercept YAML policy under the tools section for caption_video. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Vugola MCP server.

What risk level is caption_video? +

caption_video is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit caption_video? +

Yes. Add a rate_limit block to the caption_video rule in your Intercept 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.

How do I block caption_video completely? +

Set action: deny in the Intercept 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.

What MCP server provides caption_video? +

caption_video is provided by the Vugola MCP server (vugola-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
