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

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

## Why fl_chord_progression_voicer is rated Medium

The tool analyzes and transforms MIDI chord data by applying voice-leading principles, which is a modification operation. The changes are reversible (user can undo in FL Studio or revert to original pattern). This does not execute arbitrary code, delete data permanently, or trigger financial transactions.

From the tool's own definition: "Tool description states it 'automatically applies standard keyboard voice-leading principles' to MIDI chord patterns. This modifies MIDI data (voice-leading adjustments) in a reversible manner, consistent with Write category tools (update, modify)."

## Use case

AI agents use fl_chord_progression_voicer to create or update resources in FL Studio MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FL Studio MCP Server environment.
