Get information about a MIDI item.
AI agents call get_midi_item 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.
This tool retrieves metadata or properties about an existing MIDI item in REAPER DAW. It performs no modifications, deletions, or external operations—merely fetching and returning information. This is a standard Read operation with minimal risk; misuse would only retrieve data the user already has access to within their DAW project.
From the tool's definition Tool name 'get_midi_item' and description 'Get information about a MIDI item' indicate data retrieval with no modification. The verb 'get' and phrase 'Get information' are characteristic of Read operations that query state without side effects.
Documented attack patterns abuse exactly the kind of access get_midi_item 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 get_midi_item:
{
"version": "1",
"default": "deny",
"tools": {
"get_midi_item": {}
}
}get_midi_item is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get information about a MIDI item. 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 get_midi_item: 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.
get_midi_item 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_midi_item 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_midi_item. 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_midi_item 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.
Free to start. No card required.
