AI agents call get_video_options to retrieve information from Posterly without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns metadata about video generation options—durations, resolutions, aspect ratios, credit costs—without creating, modifying, executing, or consuming resources. It is a pure data retrieval operation with no side effects, fitting the Read category for low severity.
From the tool's definition Tool is explicitly described as "List read-only" and "does not generate video or spend credits." It retrieves configuration options and estimates without side effects.
Attacks that exploit this kind of access
List read-only Veo video generation options, input modes, durations, resolutions, aspect ratios, and credit-cost estimates. This does not generate video or spend credits. It is categorised as a Read tool in the Posterly MCP Server, which means it retrieves data without modifying state.
Register the Posterly MCP server in PolicyLayer and add a rule for get_video_options: 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 Posterly. Nothing to install.
get_video_options 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 get_video_options 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 get_video_options. 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.
get_video_options is provided by the Posterly MCP server (posterly-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
