Implementation Reference
- The `set_caption` tool handler is decorated with `@mcp.tool()` and executes a call to the Lightroom metadata API via `_call("metadata.set_caption", payload)`.
@mcp.tool() async def set_caption(caption: str, local_ids: list[int] | None = None) -> dict[str, Any]: """Set Lightroom caption metadata for selected photos or local_ids.""" payload: dict[str, Any] = {"caption": str(caption)} ids = validate_local_ids(local_ids) if ids: payload["local_ids"] = ids return await _call("metadata.set_caption", payload)
