AI agents use send_url 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 send_url 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.

These attack patterns abuse exactly the kind of access send_url gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Loads a web page by URL on a display using a full-page iframe, immediately replacing whatever is currently shown. Use this when the user wants to show an external website, dashboard or web app on a display. Provide content_description whenever available so get_display_content can communicate intent without forcing read_display_html. The URL must be an absolute HTTP or HTTPS address. Check get_display_capabilities first to confirm connectivity and browser/runtime support before relying on a remote page. Use this only when the external page already has the desired design quality; otherwise prefer send_html and load render_premium_display_html or read agentview://public/design-system so you can generate a premium display-native experience yourself. Requires authentication with at least content_only scope. Returns id, name, duration, file and version.. 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 send_url: 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.
send_url 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 send_url 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 send_url. 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.
send_url is provided by the agentView MCP server (https://agentview.de/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
