Codex-specific workflow

Run Convert Excel to PDF as a Codex MCP task

Use the active workspace as the source of truth. Ask Codex to identify the Excel file ID and any output naming requirements, select medux_excel_to_pdf, 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_excel_to_pdf through Medux MCP to convert Excel to PDF.
First inspect and identify the Excel file ID and any output naming requirements.
Show me the exact tool arguments before execution.
After the task completes, return the converted PDF and verify that the PDF opens and the expected worksheets, tables, and page order are present.

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 converted PDF. The final check is explicit: confirm that the PDF opens and the expected worksheets, tables, and page order are present.

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_excel_to_pdf 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 Excel to PDF

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_excel_to_pdf 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.
