Import Ae Comps
import_ae_compsImports After Effects compositions from an .aep file as Dynamic Link clips, verifies requested compositions or target-bin additions, and returns new item nodeIds and names for timeline placement.
Instructions
Import After Effects compositions from an .aep file as Dynamic Link clips, failing closed when the file does not exist or when the target bin gains no items. Returns each new item's nodeId and name for placement (add_to_timeline, replace_clip). With comp_names the result is verified only when every requested composition is read back by name and source .aep. Importing all comps verifies the target-bin item-count increase only, because the expected set is unknown; its items list is informational and is omitted when the bin's items cannot be read.

}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| comp_names | No | Array of composition names to import. If omitted, imports all comps. | |
| target_bin | No | Target bin name or node ID (optional) | |
| ae_project_path | Yes | Full path to the .aep file | |
| 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. |
