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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "set_narrator_voice",
    "arguments": {
      "voice_id": "<voice_id>",
      "project_id": "<project_id>"
    }
  }
}
```

## Why set_narrator_voice is rated Medium

The tool creates or modifies project metadata (the narrator voice setting) but does not execute the actual voiceover generation (that's handled by generate_voiceover). It is reversible—the voice can be changed again before voiceover is generated. This qualifies as Write rather than Execute because it merely configures a parameter; the actual execution and rendering occurs elsewhere.

From the tool's own definition: "'Set the project's narrator TTS voice' — modifies project configuration by selecting a voice parameter that will be used in subsequent voiceover generation. This is a reversible modification of project state."

## Use case

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

## Recommended policy (PolicyLayer)
