Get notes in a MIDI item (capped at max_results to limit context size).
AI agents call midi_get_notes to retrieve information from ReaperMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries MIDI note data from a project without modifying, deleting, or executing any operations. It has no side effects and poses minimal risk if called inappropriately by an AI agent—the worst outcome would be retrieving unwanted MIDI information from the project.
From the tool's definition Tool name 'midi_get_notes' and description 'Get notes in a MIDI item' indicate retrieval of data with no modification. The note about 'capped at max_results to limit context size' reinforces that this is a read-only query operation.
Documented attack patterns abuse exactly the kind of access midi_get_notes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ReaperMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for midi_get_notes:
{
"version": "1",
"default": "deny",
"tools": {
"midi_get_notes": {}
}
}midi_get_notes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get notes in a MIDI item (capped at max_results to limit context size). It is categorised as a Read tool in the ReaperMCP MCP Server, which means it retrieves data without modifying state.
Register the Reaper MCP server in PolicyLayer and add a rule for midi_get_notes: 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 ReaperMCP. Nothing to install.
midi_get_notes 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 midi_get_notes 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 midi_get_notes. 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.
midi_get_notes is provided by the Reaper MCP server (xdarkzx/reaper-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ReaperMCP, 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.
