## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why fl_set_plugin_param is rated High

Setting a plugin parameter triggers real-time changes in a VST/plugin within the DAW, which is an external operation affecting audio processing, synthesis, or effects. This falls under Execute as it modifies the runtime state of an external process. Severity is high because misuse could disrupt an active session or production. Confidence is reduced due to empty description.

From the tool's own definition: "Tool name 'fl_set_plugin_param' suggests setting a parameter on a plugin within FL Studio. Description is empty and uninformative."

## Use case

AI agents invoke fl_set_plugin_param to trigger actions in FL Studio MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches FL Studio MCP Server:
