Copy Effects Between Clips
copy_effects_between_clipsCopy all effects or one named effect from a source clip to a target clip, including parameter values and keyframes, with written values read back to verify the transfer.
Instructions
Copy all effects (or a specific effect) from one clip to another, including parameter values and keyframes, and read every written value back. A missing effect is added through the experimental legacy QE DOM; when the target already has that effect, its values are updated instead of stacking a second default-valued instance. Intrinsic components such as Motion and Opacity are skipped unless named. Uses the same component matching and per-property receipts as paste_clip_attributes.
Tool call template
Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| effect_name | No | Specific effect display name to copy (copies all non-intrinsic effects if omitted) | |
| source_node_id | Yes | Node ID of the source clip to copy effects from | |
| target_node_id | Yes | Node ID of the target clip to paste effects to | |
| idempotency_key | No | Optional client-chosen key (1-128 chars of A-Z a-z 0-9 . _ : -) for this intended edit. Pass a fresh key per edit and reuse it only when retrying that same edit, for example after a client-side timeout. A repeat with the same tool, key and arguments is not run again: while the first call is running it fails with IDEMPOTENCY_IN_PROGRESS (poll get_last_operations); after it finished it returns the original outcome marked replayed. A definite failure with nothing applied (receipt outcome not_applied) may be retried with the same key. Reusing a key with different arguments fails with IDEMPOTENCY_KEY_REUSED. Scoped to this MCP session (the stdio server process, or the HTTP server process when Streamable HTTP is stateless per request) and held in memory only (200 keys, 1 hour); it does not survive a restart or reconnect. Read-only invocations are never deduplicated. | |
| expected_cep_target | No | Optional reviewed CEP sequence/clip identity and exact tick ranges. Checked before every generated command; UXP refuses this CEP-only guard. | |
| expected_project_path | No | Optional absolute saved-project path. Every generated CEP command refuses before its body when the active project differs or is unsaved. UXP commands refuse this CEP-only guard; local-only tools do not inspect Premiere. Omit to keep existing behavior. |
Output Schema
| Name | Required | Description | Default |
|---|---|---|---|
| ok | Yes | Whether the tool completed successfully. | |
| data | No | Tool-specific result data when ok is true; on failure, diagnostic detail when the tool provides it. | |
| tool | Yes | The registered MCP tool name. | |
| error | No | Failure detail when ok is false. | |
| receipt | No | Versioned common mutation receipt; success never implies rendered verification. | |
| idempotency | No | Present when idempotency_key deduplicated this call: replayed is true when the original outcome was returned instead of running again. |
