AI agents call check_video_status to retrieve information from MCP Kling without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though check_video_status only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Documented attack patterns abuse exactly the kind of access check_video_status gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Kling, and nothing reaches the server without passing your rules. This is the rule we recommend for check_video_status:
{
"version": "1",
"default": "deny",
"tools": {
"check_video_status": {}
}
}check_video_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check the status of a video generation task. It is categorised as a Read tool in the MCP Kling MCP Server, which means it retrieves data without modifying state.
Register the MCP Kling MCP server in PolicyLayer and add a rule for check_video_status: 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 Kling. Nothing to install.
check_video_status 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 check_video_status 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 check_video_status. 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.
check_video_status is provided by the MCP Kling MCP server (199-mcp/mcp-kling). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
