Copy selected items to clipboard.
AI agents call copy_selected_items to retrieve information from Reaper without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Copying items to the clipboard is a read-like operation that captures data without modifying or deleting the source items. It has no destructive side effects and does not write/execute anything in the project. The clipboard state is transient and easily overwritten, so blast radius is low.
From the tool's definition Copy selected items to clipboard
Documented attack patterns abuse exactly the kind of access copy_selected_items gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Reaper, and nothing reaches the server without passing your rules. This is the rule we recommend for copy_selected_items:
{
"version": "1",
"default": "deny",
"tools": {
"copy_selected_items": {}
}
}copy_selected_items is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Copy selected items to clipboard. It is categorised as a Read tool in the Reaper MCP Server, which means it retrieves data without modifying state.
Register the Reaper MCP server in PolicyLayer and add a rule for copy_selected_items: 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 Reaper. Nothing to install.
copy_selected_items 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 copy_selected_items 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 copy_selected_items. 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.
copy_selected_items is provided by the Reaper MCP server (twelvetake-studios/reaper-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Reaper, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
