Overview

AI-generated overview

Cuts audio clips from YouTube, TikTok, Instagram or SoundCloud links as MP3/WAV with short-lived download links, and fetches timestamped transcripts.

What you can do
  • Cut audio from a YouTube, TikTok, Instagram or SoundCloud URL and get a short-lived download link, plus an editor link for adjusting the selection
  • Fetch timestamped captions for those links when the platform provides them, to pick a start and end time for a cut
  • Re-cut an existing clip card to a new start and end, reusing the audio already extracted
  • Send feedback to the developers about whether a task succeeded or needed a missing capability
When to use it
Useful when someone wants a short audio excerpt from a social or video link, or wants captions to choose the exact segment before cutting. It suits quick clip extraction in chat rather than bulk downloading or editing.
Requirements
A remote MCP endpoint; no package, account, API key or environment variable is declared. The source links must be publicly reachable by the service, and the returned download links expire after about an hour.
Before you install
The service downloads and processes third-party media, so check that you have the right to use the source content and that its terms allow it. Download links are short-lived and must be requested again once expired. The feedback tool reports task outcomes to the developers, and the server declares no authentication.

Installation

In SourceWeft

  1. Open Samplecut in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.samplecut%2Fsamplecut/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

cut_audio

Cut audio

Cut audio from a YouTube, TikTok, Instagram, or SoundCloud URL and return a short-lived download link. Lead with download_url for cut/download requests; offer editor_url when the user wants to tweak the selection. Links expire after about an hour — ask again in chat for a fresh cut if expired. Omit start_sec and end_sec for the full track. format defaults to mp3 (wav allowed). clip_id and peaks drive the interactive clip card some chat apps show; do not show them to the user. If the user adjusted the clip in the card, read the widget context for the current range and download link before answering follow-ups.

Parametersurlrequiredformatcontextrequiredend_secllm_modelrequiredstart_secduration_secconversation_id

get_transcript

Get transcript

Fetch timestamped captions for a YouTube, TikTok, Instagram, or SoundCloud URL when the platform provides them. Use segment start_sec/end_sec (or the flat text) to choose a cut range, then call cut_audio with the same URL and those times. When available is false there are no captions — do not invent lyrics or timestamps; tell the user to pick times another way. Optional lang is a BCP-47 code (default en). No job_id is returned.

Parametersurlrequiredlangcontextrequiredllm_modelrequiredconversation_id

retrim_clip

Adjust clip

Re-cut a clip from Samplecut's clip card to a new start/end, reusing the audio already extracted for it. Called by the interactive card; to cut something new, use cut_audio.

send_feedback

Send feedback

Tell Samplecut's developers how the user's task went. Call it once after you finish or give up on a task where you used these tools, with task_completed set to whether the user got what they wanted. Use feedback_type "missing_capability" when the goal needed something these tools do not do (for example naming a song or separating vocals), even if you finished it another way; "issue" when a tool failed, or its result was wrong or confusing; "praise" when it went well. This only records feedback. No links, names or personal details.
