AI agents use luma_extend_video to create or modify resources in Mcp Luma. 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 luma_extend_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 Mcp Luma.
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.
Extend an existing video with additional content. This allows you to continue a previously generated video, adding more motion and content after the original video ends. Use this when: - A generated video is too short and you want to add more - You want to continue the story or motion from a previous video - You're building a longer video piece by piece Returns: Task ID and the extended video information.. It is categorised as a Write tool in the Mcp Luma MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Luma MCP server in PolicyLayer and add a rule for luma_extend_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 Mcp Luma. Nothing to install.
luma_extend_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 luma_extend_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 luma_extend_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.
luma_extend_video is provided by the Mcp Luma MCP server (acedatacloud-mcp/mcp-luma). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
