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

Sets or clears the default idle content for a display. Idle content is shown whenever the display has no active live content. Provide html to set idle content, or omit it to clear idle content. Provide content_description to make later state reads easier for agents. Requires admin scope.. It is categorised as a Write tool in the Agentview MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agentview MCP server in PolicyLayer and add a rule for set_idle_content: 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 Agentview. Nothing to install.
set_idle_content 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 set_idle_content 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 set_idle_content. 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.
set_idle_content is provided by the Agentview MCP server (rafaelkocurek-nvob/agentview). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
