The Medux operation and request fields are shared. Switch tabs for the client-specific prompt, approval pattern, screenshots, and walkthrough.
Codex-specific workflow
Run Remove an Image Background as a Codex MCP task
Use the active workspace as the source of truth. Ask Codex to identify the source image file ID and supported output settings, select medux_image_remove_background, 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_image_remove_background through Medux MCP to remove an image background.
First inspect and identify the source image file ID and supported output settings.
Show me the exact tool arguments before execution.
After the task completes, return the background-removed image and verify that the main subject is retained cleanly and the background is transparent or removed as requested.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 background-removed image. The final check is explicit: confirm that the main subject is retained cleanly and the background is transparent or removed as requested.
What this tutorial does
Medux operation
Create an image processing task that removes the background from an uploaded image.
Agent workflow
Codex selects medux_image_remove_background, 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 image and create an asset before calling this endpoint.
- Requires an existing image file id.
Prompt Codex
Start with a clear instruction that names the Medux operation and the intended inputs.
Remove the background from the uploaded image {file id}.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. |
region.height | int32 | Optional | Provide the value described in the API reference. |
region.width | int32 | Optional | Provide the value described in the API reference. |
region.x | int32 | Optional | X coordinate of the region's top-left corner in pixels. |
region.y | int32 | Optional | Y coordinate of the region's top-left corner in pixels. |
title | string | Optional | Provide the value described in the API reference. |
Step-by-step workflow
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 Image Background Removal
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_image_remove_background 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.

Can Codex use the Medux Create Image Background Removal API through MCP?
Codex can call the medux_image_remove_background Medux MCP tool to create an image processing task that removes the background from an uploaded image. 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_image_remove_background. Review its arguments before approval and consult the API reference for the current contract.
Claude-specific workflow
Run Remove an Image Background as a Claude MCP workflow
Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the source image file ID and supported output settings before proposing medux_image_remove_background. 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 remove an image background with Medux MCP.
Restate which input fulfills each role: the source image file ID and supported output settings.
Propose the medux_image_remove_background call and summarize its arguments before asking for approval.
When it finishes, return the background-removed image with a checklist confirming that the main subject is retained cleanly and the background is transparent or removed as requested.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 background-removed image plus a concise validation checklist confirming that the main subject is retained cleanly and the background is transparent or removed as requested.
