Apply a single audio or video effect to selected clips, a specific track, or all compatible clips, with preflight checks and component-count readback to verify each target.
Instructions
Apply one audio or video effect to compatible selected clips, a compatible track, or all compatible clips. Every target is preflighted and then checked by component-count readback.

}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| target | Yes | Which clips to apply to: selected clips, all on a track, or all in sequence | |
| track_type | No | Track type (required when target is 'track') | |
| effect_name | Yes | Display name of the effect to apply (e.g., 'Gaussian Blur', 'Lumetri Color') | |
| track_index | No | Track index (required when target is 'track') | |
| 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. |
