Objects and creatures
List and read your saved objects and creatures, generate images and variants, approve main images, and animate turntable and idle clips from an AI assistant.
The object and creature tools let an assistant use the props, products and creatures in your library: items and beings with a locked look that stay the same in every shot. The assistant lists and reads them, generates images and variants, approves main images, and animates short motion clips. Objects and creatures work the same way; creatures add a free-text species. Read Objects and Creatures for the same work in the app.
Objects and creatures are created in the app. There is no MCP tool that creates one.
Object tools
list_objects
Lists your objects: props, accessories and physical items you reuse across shots. Each row has the name, description, main image and the number of variants. Newest first.
Permission: assets:read. Credits: free.
| Parameter | Type | Notes |
|---|---|---|
search | string | Up to 5 words, up to 200 characters. Every word must appear in the object's name or description, in any case. A blank value means no search. Use it when the user names one. |
limit | integer | From 1 to 100. Default 50. |
Returns: the objects. Call get_object for the variant URLs.
get_object
Returns one object in full: every variant with its name and URL, and the reference photos.
Permission: assets:read. Credits: free.
| Parameter | Type | Notes |
|---|---|---|
id | string | Required. The object id from list_objects. |
Returns: the object. An error when it does not exist or is not yours.
generate_object
Generates an image of an object (kind: "main") or a variant (kind: "asset"). The result is not saved on an object.
Permission: workflows:execute. Credits: the price of the image model.
| Parameter | Type | Notes |
|---|---|---|
name | string | Required. The object's name. |
kind | string | main (default) or asset. |
description, style | string | What the object looks like. |
category | string | furniture, vehicle, weapon, food, clothing, electronics, nature, tool, animal or other. |
asset_type | string | For asset: angles, materials, variations or custom. |
variant | string | For asset: for example front, wood or weathered. |
model | string | The image model. Default gpt-image-2. |
source_image_url | string | A source picture. |
Returns: a job id.
approve_object_main_image
Makes a finished candidate the object's main image, and has a vision model describe its form, material, condition and purpose in the canonical description.
Permission: assets:write. Credits: one Claude Sonnet 4.6 vision call for the description, charged for the tokens it used (how LLM calls are charged). The approval is never refused for credits. When your balance is too low for the description, the image is still approved and the description is skipped. Run recaption_object later to write it.
| Parameter | Type | Notes |
|---|---|---|
object_id | string | Required. The object. |
candidate_job_id | string | Required. A completed image job of yours, such as a generate_object result. A job made for another object returns candidate_object_mismatch. |
expected_updated_at | string | The object's updatedAt. When the object changed since, the call returns concurrent_modification with the new value. |
Returns: the main image URL and the description. When the description fails, the image is still set and the description is empty; run recaption_object.
recaption_object
Has the vision model describe the current main image again, in about 80 to 120 words, and saves it as the canonical description.
Permission: assets:write. Credits: one Claude Sonnet 4.6 vision call, charged for the tokens it used, like the approval's description.
| Parameter | Type | Notes |
|---|---|---|
object_id | string | Required. The object. |
Returns: the new description. main_image_required when the object has no main image, and caption_failed when the description fails.
generate_object_motion
Animates an object into a short clip, such as "slow 360-degree rotation", "object hovering with subtle bob" or "parallax pan from left to right".
Permission: workflows:execute. Credits: the price of the video model. The default, Kling 2.5 Turbo Pro, makes a 5-second clip for 138 credits.
| Parameter | Type | Notes |
|---|---|---|
motion_prompt | string | Required. The object's or the camera's movement, up to 2,000 characters. |
source_image_url | string | Required. The first frame, usually the object's approved main image. |
name | string | Required. The object's name, used as context in the prompt. |
provider | string | kling-turbo (default), kling, kling-3.0, minimax, hailuo-2.3, wan-i2v, seedance-2-mini or bytedance-lite. |
aspect_ratio | string | 1:1 (default, for product framing), 3:4, 16:9, 9:16 or 4:3. |
attach_to_object_id | string | Saves the clip in the object's motion clips. The ownership is checked before any credits are reserved. |
attach_name | string | The name of the saved clip. |
refine_from_video_url | string | Refines an existing clip with a new prompt, as video to video, for example "same shot but faster rotation". |
canonical_description, category, style | string | Extra context for the prompt. |
Returns: a job id. The card plays the clip when it is ready.

Frequently asked questions
Can an assistant create a new object or creature?
Not as a saved row. There is no create tool for objects or creatures; create them in the app. The assistant can then list them, read them, generate images and clips for them, and approve main images made for them.
Why does approving a main image fail with a mismatch error?
A candidate job made for another object or creature returns candidate_object_mismatch or candidate_creature_mismatch. A candidate not linked to any row, such as a generate_object result, can be approved.
What motion clips can I make of a product?
Short clips such as a slow 360-degree rotation, a hover with a subtle bob, or a parallax pan. generate_object_motion uses square framing and Kling 2.5 Turbo Pro by default.
What is the difference between an object and a creature?
An object is a prop, product, vehicle or other physical item. A creature is an animal or a non-human being, with a free-text species such as dragon or wolf, and pose variants instead of material variants.
