Claude-specific workflow

Run Merge PDF Files as a Claude MCP workflow

Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the PDF file IDs in the intended merge order before proposing medux_merge_pdf. 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 merge PDF files with Medux MCP.
Restate which input fulfills each role: the PDF file IDs in the intended merge order.
Propose the medux_merge_pdf call and summarize its arguments before asking for approval.
When it finishes, return the merged PDF with a checklist confirming that all source PDFs are present once and the final page order is correct.

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 merged PDF plus a concise validation checklist confirming that all source PDFs are present once and the final page order is correct.

What this tutorial does

Medux operation

Merge multiple PDF files into a single PDF output.

Agent workflow

Claude selects medux_merge_pdf, presents the arguments for review, calls Medux, and reports the response.

Before you start

Authentication

Authentication is required via Authorization header.

Preconditions

Upload each source file and create file references 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 Claude

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

Merge multiple PDF files into a single PDF output.

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_ids`	array<string>	Required	Input PDF file id list.
`model_id`	string	Optional	Merge PDF model id. Default: merge-pdf-default.
`title`	string	Optional	Optional task title.

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_merge_pdf 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 Merge PDF

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_merge_pdf 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.
