How to trim an audio file with Claude MCP and Medux
Use Claude and Medux through MCP to cut an audio file to a specified time range. This guide keeps file roles and constraints in context, reviews the proposed call, and validates the returned result.

Run Trim an Audio File as a Claude MCP workflow
Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the source audio and exact start and end times before proposing medux_trim_audio. 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 trim an audio file with Medux MCP.
Restate which input fulfills each role: the source audio and exact start and end times.
Propose the medux_trim_audio call and summarize its arguments before asking for approval.
When it finishes, return the trimmed audio with a checklist confirming that the output begins and ends at the requested times and remains playable.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 trimmed audio plus a concise validation checklist confirming that the output begins and ends at the requested times and remains playable.
What this tutorial does
Medux operation
Cut an audio file to a specified time range.
Agent workflow

- 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.
Cut an audio file to a specified time range.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 audio file id. |
start_time | string | Optional | e.g. 00:00:05 |
end_time | string | Optional | e.g. 00:01:00 |
duration | string | Optional | e.g. 00:00:55. At least one of start time/end time/duration required. |

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 Claude to run Trim Audio
Use one direct instruction with the intended values. Claude 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_trim_audio 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.
