List all available aspect ratios for Luma video generation. Shows all available aspect ratio options with their use cases. Use this to understand which aspect ratio to choose for your video. Returns: Table of all aspect ratios with their descriptions and use cases.
Part of the Mcp Luma MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call luma_list_aspect_ratios 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_list_aspect_ratios 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.

Returns: Table of all aspect ratios with their descriptions and use cases. . It is categorised as a Read tool in the Mcp Luma MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for luma_list_aspect_ratios. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mcp Luma MCP server.
luma_list_aspect_ratios 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_list_aspect_ratios 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.
Set action: deny in the Intercept policy for luma_list_aspect_ratios. 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_list_aspect_ratios is provided by the Mcp Luma MCP server (acedatacloud-mcp/mcp-luma). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
