Claude-specific workflow

Run Resize a Video as a Claude MCP workflow

Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the source video and exact target width and height before proposing medux_resize_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 resize a video with Medux MCP.
Restate which input fulfills each role: the source video and exact target width and height.
Propose the medux_resize_video call and summarize its arguments before asking for approval.
When it finishes, return the resized video with a checklist confirming that the output dimensions 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 resized video plus a concise validation checklist confirming that the output dimensions match the request and the full video plays correctly.

Step-by-step workflow

Connect Medux MCP to Claude

Add the Medux remote MCP endpoint to Claude, provide an authorized credential, and confirm that the medux_resize_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 Claude to run Resize Video

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

Review and approve the tool call

Check that the tool is medux_resize_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.
