Codex-specific workflow

Run Convert PDF Tables to Excel as a Codex MCP task

Use the active workspace as the source of truth. Ask Codex to identify the source PDF file ID, select medux_pdf_to_excel, 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_pdf_to_excel through Medux MCP to convert PDF tables to Excel.
First inspect and identify the source PDF file ID.
Show me the exact tool arguments before execution.
After the task completes, return the converted Excel workbook and verify that the workbook opens and table rows, columns, and values align with the source PDF.

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 Excel workbook. The final check is explicit: confirm that the workbook opens and table rows, columns, and values align with the source PDF.

What this tutorial does

Medux operation

Before you start

Authentication

Authentication is required via Authorization header.

Preconditions

Upload the source file and create a file reference before calling this endpoint.
Successful requests return a Medux task record immediately. Use the task query or sync endpoints to track completion.
All file inputs must be uploaded and persisted as file references before submission.

Prompt Codex

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

Extract tables from a PDF into an Excel (.xlsx) file.

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
`input_file_id`	string	Required	Input PDF file id.
`pages`	string	Optional	Pages to extract, default all. Default: all.
`flavor`	string	Optional	Extraction method. Default: stream.

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_pdf_to_excel 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 PDF to Excel

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_pdf_to_excel 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.
