AI agents call get_selected_items to retrieve information from Reaper Reapy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves the currently selected items in REAPER without modifying, creating, or deleting anything. It is a pure data retrieval operation with no side effects or irreversible consequences. Confidence is slightly reduced due to the empty description, but the semantic meaning of 'get_selected' is unambiguous.
From the tool's definition Tool name 'get_selected_items' indicates a retrieval operation with no side effects. The empty description limits direct confirmation, but the naming convention and context as part of a DAW control interface clearly suggest a query operation.

PolicyLayer is an MCP gateway — it sits between your AI agents and Reaper Reapy, and nothing reaches the server without passing your rules. This is the rule we recommend for get_selected_items:
{
"version": "1",
"default": "deny",
"tools": {
"get_selected_items": {}
}
}get_selected_items is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_selected_items. It is categorised as a Read tool in the Reaper Reapy MCP Server, which means it retrieves data without modifying state.
Register the Reaper Reapy MCP server in PolicyLayer and add a rule for get_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 Reapy. Nothing to install.
get_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 get_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 get_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.
get_selected_items is provided by the Reaper Reapy MCP server (wegitor/reaper-reapy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
