Get the name of an FX parameter.
AI agents call track_fx_get_param_name 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 performs a simple lookup/retrieval of parameter names from FX settings. It has no side effects, does not modify state, does not execute code or commands, and does not delete or move data. It is purely informational, making it a Read category tool with low severity since accessing metadata about audio effects poses minimal risk in a music production context.
From the tool's definition Tool name 'track_fx_get_param_name' and description 'Get the name of an FX parameter' indicate a retrieval operation that queries existing FX parameter metadata without modification or execution.

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 track_fx_get_param_name:
{
"version": "1",
"default": "deny",
"tools": {
"track_fx_get_param_name": {}
}
}track_fx_get_param_name is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the name of an FX parameter. 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 track_fx_get_param_name: 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.
track_fx_get_param_name 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 track_fx_get_param_name 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 track_fx_get_param_name. 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.
track_fx_get_param_name 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.
