Codex-specific workflow

Run Create a Text-Driven Avatar Video as a Codex MCP task

Use the active workspace as the source of truth. Ask Codex to identify the script, avatar ID, voice ID, and supported video settings, select medux_video_create_text_driven, 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_video_create_text_driven through Medux MCP to create a text-driven avatar video.
First inspect and identify the script, avatar ID, voice ID, and supported video settings.
Show me the exact tool arguments before execution.
After the task completes, return the generated talking-avatar video and verify that the avatar, voice, and spoken script match the request and the full video plays correctly.

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 generated talking-avatar video. The final check is explicit: confirm that the avatar, voice, and spoken script match the request and the full video plays correctly.

What this tutorial does

Medux operation

Generate an avatar video from text using a reusable avatar and voice.

Agent workflow

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

Before you start

Authentication

  • Authentication is required via Authorization header.

Preconditions

  • Prepare avatar and voice assets before calling this endpoint.
  • Requires avatar asset id, voice asset id, and non-empty text.
  • Avatar and voice IDs can come from your Media Assets or official public assets.
  • Also accepts optional duration seconds, links, clarity, aspect ratio, and model.

Prompt Codex

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

Create a 7 second 1080P 16:9 talking video from this script using avatar asset id {avatar asset id}, voice asset id {voice asset id}, and model id talking-video-text-standard.

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.

Step-by-step workflow

01

Connect Medux MCP to Codex

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

02

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.

03

Ask Codex to run Create Text Driven Video

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

04

Review and approve the tool call

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

05

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 Text Driven Video API through MCP?

Codex can call the medux_video_create_text_driven Medux MCP tool to generate an avatar video from text using a reusable avatar and voice. 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_video_create_text_driven. Review its arguments before approval and consult the API reference for the current contract.

Claude-specific workflow

Run Create a Text-Driven Avatar Video as a Claude MCP workflow

Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the script, avatar ID, voice ID, and supported video settings before proposing medux_video_create_text_driven. 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 text-driven avatar video with Medux MCP.
Restate which input fulfills each role: the script, avatar ID, voice ID, and supported video settings.
Propose the medux_video_create_text_driven call and summarize its arguments before asking for approval.
When it finishes, return the generated talking-avatar video with a checklist confirming that the avatar, voice, and spoken script match the request and the full video plays correctly.

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 generated talking-avatar video plus a concise validation checklist confirming that the avatar, voice, and spoken script match the request and the full video plays correctly.

Quick answer

How do I create a text-driven avatar video with Medux MCP?

Connect either Codex or Claude to Medux MCP, prepare the required inputs, review the proposed medux_video_create_text_driven 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 a text-driven avatar video

This tutorial addresses developer workflows for text-to-avatar video API and AI talking avatar from text 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 a text-driven avatar 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.

Production, trust, and developer intent

Add consent and review controls when you create a text-driven avatar video

Treat this as a consent-based, auditable workflow for create a text-driven avatar video. 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.
