Codex-specific workflow

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

Use the active workspace as the source of truth. Ask Codex to identify the source video file ID and a recognizable asset title, select medux_avatar_clone_by_video, 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_video through Medux MCP to create an AI avatar from video.
First inspect and identify the source video 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 source video.

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 source video.

What this tutorial does

Medux operation

Create a reusable avatar asset from an uploaded video file.

Agent workflow

Codex selects medux_avatar_clone_by_video, 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 file id created from an uploaded source file.
Upload and create the source asset first.

Prompt Codex

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

Clone a reusable avatar from the uploaded source video {file id}. Title it Official avatar 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_video 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 Video

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_video 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.

Frequently asked questions

Can Codex use the Medux Create Avatar by Video API through MCP?

Codex can call the medux_avatar_clone_by_video Medux MCP tool to create a reusable avatar asset from an uploaded video file. This guide covers the required inputs, approval flow, result handling, and the matching API reference.

Which MCP tool does this tutorial use?

This workflow uses medux_avatar_clone_by_video. Review its arguments before approval and consult the API reference for the current contract.

Claude-specific workflow

Run Create an AI Avatar from Video as a Claude MCP workflow

Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the source video file ID and a recognizable asset title before proposing medux_avatar_clone_by_video. That context checkpoint makes the file roles and desired outcome easy to correct before any Medux call is approved.

Claude prompt pattern

Using the assets and requirements in this conversation, help me create an AI avatar from video with Medux MCP.
Restate which input fulfills each role: the source video file ID and a recognizable asset title.
Propose the medux_avatar_clone_by_video call and summarize its arguments before asking for approval.
When it finishes, return the reusable avatar asset ID with a checklist confirming that the avatar task completes and the returned asset belongs to the intended source video.

Context checkpoint

Have Claude summarize the intended transformation, identify every source asset by role, and list the important constraints. Review that summary together with the proposed tool arguments; correct the conversation first if a file, order, time range, or setting is ambiguous.

Result verification

Keep the Medux task ID in the conversation while Claude checks progress. When processing ends, ask for the reusable avatar asset ID plus a concise validation checklist confirming that the avatar task completes and the returned asset belongs to the intended source video.

Quick answer

How do I create an AI avatar from video with Medux MCP?

Connect either Codex or Claude to Medux MCP, prepare the required inputs, review the proposed medux_avatar_clone_by_video call, and verify the returned result. The tabs above keep client-specific prompting on one canonical page.

Can I use the same Medux tool in Codex and Claude?

Yes. The client interaction differs, but both use the same Medux MCP tool and API request contract shown in this tutorial.

Related developer intent

Use AI agents to create an AI avatar from video

This tutorial addresses developer workflows for AI avatar API from video and create a reusable video avatar by making the task repeatable through the Medux API. Codex or Claude can prepare inputs, show the MCP tool arguments for approval, monitor processing, and return an output that can be checked against the original request.

This capability also fits a broader AI lip sync and talking-avatar pipeline: prepare an approved voice or avatar asset, run audio-to-video lip sync, then verify timing, mouth motion, and final playback.

Can Codex or Claude create an AI avatar from video through Medux MCP?

Yes. Use the client-specific tab above to prepare the inputs, review the Medux tool call, run the operation, and verify the returned result. The linked API reference remains the source of truth for supported fields and limits.

Consent-based avatar creation

Build a consent-based AI avatar API workflow

Create an avatar only from an image or video you own or have explicit permission to use. Keep the authorization record, approved source asset, Medux task ID, and accepted avatar together so developers can audit how the reusable digital likeness was created.

For production use, add identity and consent checks, role-based access, retention rules, and human approval in the integrating application. This tutorial does not claim automatic consent verification.

What should an AI avatar API with consent checks record?

Record who authorized the likeness, which source file was approved, the intended use, the Medux task ID, the returned avatar asset, and who approved it for reuse.
