AI agents call luma_extend_video_from_url to retrieve information from Mcp Luma without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though luma_extend_video_from_url only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Extend an existing video using its URL. Similar to luma_extend_video, but uses the video URL instead of video ID. This is useful when you have the video URL but not the original video ID. Use this when: - You have the video URL from a previous generation - You want to extend a video but don't have the video_id Returns: Task ID and the extended video information.. It is categorised as a Read tool in the Mcp Luma MCP Server, which means it retrieves data without modifying state.
Register the Mcp Luma MCP server in PolicyLayer and add a rule for luma_extend_video_from_url: 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_from_url is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the luma_extend_video_from_url 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_from_url. 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_from_url 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.
