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

```json

  "jsonrpc": "2.0",

## Why add_clip_marker is rated Medium

Adding a marker is a reversible modification operation that creates metadata within a DaVinci Resolve project. While markers can organize and annotate clips, they do not execute external code, delete data, or cause financial impact. This aligns with Write category—creating or modifying data that can be undone.

From the tool's own definition: "Tool name 'add_clip_marker' indicates creation of marker metadata on a video clip. Sibling tools like 'add_clip_flag', 'add_keyframe', and 'add_render_job' are all Write operations that create or modify timeline/project state reversibly."

## Use case

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

## Recommended policy (PolicyLayer)
