Claude-specific workflow

Run Create a Medux Asset as a Claude MCP workflow

Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the uploaded file reference, asset type, and asset metadata before proposing medux_create_asset. 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 create a Medux asset with Medux MCP.
Restate which input fulfills each role: the uploaded file reference, asset type, and asset metadata.
Propose the medux_create_asset call and summarize its arguments before asking for approval.
When it finishes, return the new Medux asset record with a checklist confirming that the asset points to the intended uploaded file and has the correct type and metadata.

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 new Medux asset record plus a concise validation checklist confirming that the asset points to the intended uploaded file and has the correct type and metadata.

What this tutorial does

Medux operation

Create an asset record from a file that was uploaded through a direct upload URL.

Agent workflow

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

Before you start

Authentication

Authentication is required via Authorization header.

Preconditions

Requires reusable asset metadata.
Uploaded MEDIA files use file id directly and do not need this endpoint.

Prompt Claude

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

Use Medux to run Create Asset. Review the required inputs, call medux_create_asset, wait for the result if a task is returned, and report the output clearly.

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
`category`	string	Optional	Asset category, used for validation and later rendering. Allowed values: - CATEGORY UNDEFINED - Not specified. - MEDIA - Uploaded source media. - AVATAR - Reusable avatar asset. - VOICE - Reusable voice asset.
`file_size_bytes`	int64	Optional	Original file size, in bytes.
`name`	string	Optional	Display name provided by the user. This value may be empty.
`storage_object.key`	string	Optional	Provide the value described in the API reference.
`storage_object.url`	string	Optional	Provide the value described in the API reference.

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_create_asset 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 Create Asset

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_create_asset 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.
