Codex-specific workflow

Run Create an AI Avatar from an Image as a Codex MCP task

Use the active workspace as the source of truth. Ask Codex to identify the portrait image file ID and a recognizable asset title, select medux_avatar_clone_by_image, and keep the Medux task ID and returned output with the rest of the project. Naming the input roles and the expected result prevents an agent from guessing which file should be used where.

Codex prompt pattern

In this workspace, use medux_avatar_clone_by_image through Medux MCP to create an AI avatar from an image.
First inspect and identify the portrait image file ID and a recognizable asset title.
Show me the exact tool arguments before execution.
After the task completes, return the reusable avatar asset ID and verify that the avatar task completes and the returned asset belongs to the intended portrait.

Approval gate

Before approving the call, compare the selected tool, file or asset IDs, ordering, timing, and output settings with the request. If a local filename was mapped to an uploaded Medux file ID, keep that mapping visible so it can be audited later.

Result verification

Let Codex monitor an asynchronous task until it reaches a terminal state, then save or report the reusable avatar asset ID. The final check is explicit: confirm that the avatar task completes and the returned asset belongs to the intended portrait.

What this tutorial does

Medux operation

Create a reusable avatar asset from an uploaded image file.

Agent workflow

Codex selects medux_avatar_clone_by_image, presents the arguments for review, calls Medux, and reports the response.

Before you start

Authentication

Authentication is required via Authorization header.

Preconditions

Requires a valid image file id.
Use a clear portrait-style image for best results.

Prompt Codex

Start with a clear instruction that names the Medux operation and the intended inputs.

Clone a reusable avatar from the uploaded portrait image {file id}. Title it Official avatar image clone sample.

Request fields to review

Confirm these values before approving the MCP tool call. The linked API page remains the source of truth for current limits and response semantics.

Field	Type	Requirement	Purpose
`file_id`	string	Required	Provide the value described in the API reference.
`title`	string	Optional	Provide the value described in the API reference.

Step-by-step workflow

Connect Medux MCP to Codex

Add the Medux remote MCP endpoint to Codex, provide an authorized credential, and confirm that the medux_avatar_clone_by_image tool is available.

Prepare the required inputs

Prepare the source files, asset IDs, text, or settings required by the operation. Upload local media first when the tool requests file IDs.

Ask Codex to run Create Avatar by Image

Use one direct instruction with the intended values. Codex should select the Medux tool and show the proposed arguments before execution.

Review and approve the tool call

Check that the tool is medux_avatar_clone_by_image and that each file ID, task ID, option, and output setting matches your request before approving it.

Check the Medux response

If Medux returns an asynchronous task, let the agent monitor it until completion; otherwise review the immediate response and save any result identifiers or output URLs.
