Codex-specific workflow

Run Generate Video from a Medux Project as a Codex MCP task

Use the active workspace as the source of truth. Ask Codex to identify the project ID and supported generation options, select medux_create_video_by_project, 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_create_video_by_project through Medux MCP to generate video from a Medux project.
First inspect and identify the project ID and supported generation options.
Show me the exact tool arguments before execution.
After the task completes, return the new video-generation task and verify that the task references the intended project and reaches the expected state.

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 new video-generation task. The final check is explicit: confirm that the task references the intended project and reaches the expected state.

What this tutorial does

Medux operation

Start video generation from an existing Flyworks provider project.

Agent workflow

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

Before you start

Authentication

Authentication is required via Authorization header.

Preconditions

Requires an existing project id.
Useful when the provider project already exists upstream.

Prompt Codex

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

Use Medux to run Create Video by Project. Review the required inputs, call medux_create_video_by_project, wait for the result if a task is returned, and report the output clearly.

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
`project_id`	string	Optional	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_create_video_by_project 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 Video by Project

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_create_video_by_project 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.
