AI agents use quiz_video_update_quiz to create or modify resources in Api. 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 quiz_video_update_quiz 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 Api.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

quiz_video_update_quiz 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 quiz_video_update_quiz 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 quiz_video_update_quiz. 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.
quiz_video_update_quiz is provided by the Api MCP server (https://www.quiz.video/mcp/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
