Trim, join, resize and caption videos from a link, and pull out frames, GIFs or MP3s.
Connects to hosted video tools. Muse can check a video's length and resolution, cut clips, join up to 10 videos, reframe to 9:16 for Shorts or Reels, burn in captions, change speed, convert to GIF or MP3, grab still frames, and add a soundtrack. No API key needed.
Try asking Muse: "Take this video link, trim the first 30 seconds, and resize it to 9:16 for a Reel."

What Muse can see: It does not ask you to sign in, so it cannot see your accounts. It only sees what Muse sends it from your request.
Before it acts: Read what Muse plans to do before you approve it, and remove the app from Muse when you stop using it.

Gragg Agent Tools is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
video_infoInspect a video or audio file: duration, resolution, frame rate, codecs, and whether it has audio. url: public http(s) URL of the file (or an output_url from another tool here).video_trimCut a clip out of a video (frame-accurate). start_s / end_s are seconds from the beginning. Returns an MP4 (H.264/AAC) output_url.video_concatJoin 2-10 videos end to end into one MP4. Clips are scaled/letterboxed to one size: the first clip's size unless width/height are given. Clips without audio get silence so the result always has a track.video_resizeResize or reframe a video. Either aspect = "9:16" (Shorts/Reels/TikTok), "16:9", "1:1", "4:5", "4:3", or an explicit width and height. mode = "crop" (fill the frame, trim edges) or "pad" (fit inside, black bars).video_captionBurn a text caption/title into a video (white text on a translucent dark box). position = "top", "center" or "bottom". font_size 0 = auto (about 1/18 of the frame height). start_s/end_s (optional) limit when the text shows; default is the whole video. Up to 300 characters; use \nvideo_speedSpeed a video up or slow it down. factor 2.0 = twice as fast, 0.5 = half speed (0.25-4.0). Audio pitch is preserved.video_convertConvert media to another format. format = "mp4", "webm", "gif" (first 30 s, 480 px wide), "mp3", "m4a" or "wav" (the audio formats extract the soundtrack).video_extract_framesGrab still frames as PNG images. Either times_s = [seconds, ...] (up to 20) or count = N evenly spaced frames (1-20). Returns a list of image URLs, useful for thumbnails or for looking at a video.video_add_audioPut a soundtrack on a video. mode = "replace" (new audio only) or "mix" (blend with the original). The audio is cut to the video's length. audio_volume 0.0-2.0 scales the added track.hire_for_taskHire Gragg Robotics (a small US AI-automation company: an AI agent team plus its founder) to do a one-off job you or your user need done.

At the last check (November 15, 2026, 21:21 UTC) the endpoint was working, answering in 51ms. It is checked every 15 minutes.
It was screened on November 15, 2026 with the result "screened, no issues found". Screening checks the domain against threat feeds and reads the tools for hidden instructions and requests for passwords or card numbers. It cannot see the server's code, so grant only the access you need.
It exposes 11 tools, including video_info, video_trim, video_concat, video_resize. For example, you could ask Muse: "Take this video link, trim the first 30 seconds, and resize it to 9:16 for a Reel."
