AI agents call list_displays to retrieve information from Agentview without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though list_displays only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access list_displays gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Returns all displays accessible to the authenticated user as an array with count and display details. Use this to discover available display IDs before reading or modifying a specific display with get_display or send_html. Requires authentication with at least content_only scope; admin is not required. Each display entry includes id (8-character alphanumeric profile ID), name, status, locked, displayUrl, setupUrl, pairingUrl and other management links plus a compact runtime summary such as screen resolution, touch support, deviceClass and deviceFamily when known. Do not use this to get full details of one display — use get_display with the display_id instead.. It is categorised as a Read tool in the Agentview MCP Server, which means it retrieves data without modifying state.
Register the Agentview MCP server in PolicyLayer and add a rule for list_displays: 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.
list_displays 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 list_displays 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 list_displays. 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.
list_displays 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.
