Codex-specific workflow

Run AI Video Head Swap as a Codex MCP task

Use the active workspace as the source of truth. Ask Codex to identify the prepared swapped-head image and driving video, with each role clearly assigned, select medux_animate_head_swap, 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_animate_head_swap through Medux MCP to create a video head swap.
First inspect and identify the prepared swapped-head image and driving video, with each role clearly assigned.
Show me the exact tool arguments before execution.
After the task completes, return the animated head-swap video and verify that the output follows the driving motion and retains the intended full-head replacement.

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 animated head-swap video. The final check is explicit: confirm that the output follows the driving motion and retains the intended full-head replacement.

Capability boundary: This page targets video head swap: it animates a prepared swapped-head image with a driving video. It is distinct from still-image head swap and from image face swap, so those keywords and workflows are documented separately.

What this tutorial does

Medux operation

Animate a swapped face image with a driving video to produce a head swap video.

Agent workflow

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

Before you start

Authentication

Authentication is required via Authorization header.

Preconditions

Upload the source file and create a file reference before calling this endpoint.
Successful requests return a Medux task record immediately. Use the task query or sync endpoints to track completion.
All file inputs must be uploaded and persisted as file references before submission.

Prompt Codex

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

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
`face_image_file_id`	string	Required	Face reference image file id used for the head swap target.
`input_video_file_id`	string	Required	Driving video file id.
`width`	integer	Optional	Target output width. Default: 480.
`height`	integer	Optional	Target output height. Default: 832.
`positive_prompt`	string	Optional	Positive prompt text for the animation workflow. Default: 一个角色在说话.
`negative_prompt`	string	Optional	Negative prompt text.
`edit_prompt`	string	Optional	Edit instruction for preserving the swapped face identity. Default: 人脸保持不变.
`model_id`	string	Optional	Animate head swap model id. Default: animate-head-swap-default.
`title`	string	Optional	Optional task title.

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_animate_head_swap 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 Video Head Swap

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_animate_head_swap 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 Video Head Swap API through MCP?

Codex can call the medux_animate_head_swap Medux MCP tool to animate a swapped face image with a driving video to produce a head swap video. This guide covers the required inputs, approval flow, result handling, and the matching API reference.

Which MCP tool does this tutorial use?

Claude-specific workflow

Run AI Video Head Swap as a Claude MCP workflow

Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the prepared swapped-head image and driving video, with each role clearly assigned before proposing medux_animate_head_swap. 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 a video head swap with Medux MCP.
Restate which input fulfills each role: the prepared swapped-head image and driving video, with each role clearly assigned.
Propose the medux_animate_head_swap call and summarize its arguments before asking for approval.
When it finishes, return the animated head-swap video with a checklist confirming that the output follows the driving motion and retains the intended full-head replacement.

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 animated head-swap video plus a concise validation checklist confirming that the output follows the driving motion and retains the intended full-head replacement.

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 video head swap

This tutorial addresses developer workflows for AI video head swap and replace a head in video with AI 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 fits a broader AI video editing pipeline alongside video watermark removal, logo removal, object cleanup, resizing, and output validation for owned or authorized media.

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.

Production, trust, and developer intent

Add consent and review controls when you create an AI video head swap

Treat this as a consent-based, auditable workflow for create an AI video head swap. Use only a voice, face, avatar, or reference asset that you own or have explicit permission to process; keep the source authorization, approved prompt, Medux task ID, and accepted output together for later review.

For production use, pair the Medux API with your own consent records, identity checks, access controls, retention rules, and human approval. These tutorials promote responsible AI media use but do not claim automatic consent verification.

What makes an AI avatar or voice workflow consent-based?

Document who authorized the source material, restrict who can submit tasks, keep the approved inputs and output together, and require review before publishing or reusing a likeness or voice.
