PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

Common questions

Is Screencast MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.48.0) reached the registry 6 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Screencast MCP

An MCP server that lets an agent record the screen, _watch_ the footage, and make minimal ffmpeg edits — over stdio, on Windows.

Capture the desktop, a monitor, a window, or a region; sample a recording into frames the agent can actually look at; trim, crop, redact, annotate, zoom toward clicks, and export for GitHub or social. No cloud service, no telemetry: ffmpeg and ffprobe behind 58 typed tools.

For developers who want their coding agent to see and prove UI changes on Windows: bug repros, UI verification, and demo clips the agent records, checks, and edits itself. Capture is Windows-only; the watch and edit tools work on any OS with ffmpeg. Free for non-commercial use (CC BY-NC-ND 4.0); why not OBS, Playwright, or a screenshot MCP?

Made with the tool: start_recording with events: true , one click, then zoom { highlightClicks: true } and export_gif . How it was made · more workflows

Quick start

The fastest path: npx -y @tmhs/screencast-mcp setup checks FFmpeg 8, OCR, and speech, offers winget install Gyan.FFmpeg when FFmpeg is missing, and adds the server to Claude Desktop, Claude Code, Cursor, and VS Code (backing up each config). --dry-run shows the changes first; --test records a 3-second GIF to prove it works. Or set it up by hand:

You need Windows 10 or 11, Node.js 22+, and FFmpeg 8 or newer on PATH (winget install Gyan.FFmpeg, the full build). Older builds run most tools, but transcribe (the whisper filter) and backend: "wgc" (gfxcapture) need FFmpeg 8, and essentials or distro builds can lack them (Ubuntu LTS apt install ffmpeg gives 6.x). Capture is Windows-only; the watch, edit, and produce tools work anywhere ffmpeg runs. After connecting, ask the agent to run doctor: it reports the ffmpeg version, the filters and devices it has, OCR, and anything missing.

Add it to your client:

ClientHow
Claude Codeclaude mcp add screencast -- cmd /c npx -y @tmhs/screencast-mcp, or the plugin (the server plus bug-repro, README-demo, and UI-verify skills): /plugin install screencast --marketplace TMHSDigital/screencast-mcp (older Claude Code: /plugin marketplace add TMHSDigital/screencast-mcp, then /plugin install screencast@screencast-mcp)
Claude DesktopDownload screencast-mcp.mcpb from the latest release and open it (one click)
Cursor, VS Code, othersThe JSON config below, or step-by-step on Connect your client
{ "mcpServers": { "screencast": { "command": "npx", "args": ["-y", "@tmhs/screencast-mcp"] } } }

Then ask your agent:

Record my VS Code window for five seconds while I reproduce the bug, then show me the frames where something changed.

More in the workflows: a bug-repro GIF for a PR, a README demo, a UI verification loop, a social clip, a cheap review of a long recording, zoom toward clicks, and the whole edit in one call.

Why not just...

The core is the watch loop: the agent records, samples the footage into frames it can see, and checks what actually happened on screen. Capture only ever happens on an explicit tool call, and output lands under SCREENCAST_HOME, never in your checkout.

Instead ofThe difference
OBS, ShareX, Game BarBuilt for a person at the controls. Here the agent starts and stops the recording, looks at the frames, and makes the edits through typed tools, with no GUI step.
Playwright or Puppeteer videoBrowser pages only, and the video is a file the model never sees. Here: any window or monitor, frames returned to the model, plus wait_for_change, find_text, and screen_diff for checking what happened.
A screenshot-only MCP serverSingle stills. Here: video over time, an input event log, scene-change sampling, redaction, and export, so the agent can show a sequence, not one moment.

Tools

58 tools in 6 toolsets, generated from the server's own schemas by npm run docs (do not edit between the markers). Each name links to its reference page with every parameter, an example call, and what it returns; mcp-tools.json is the same list as JSON, and llms-full.txt all of it in one file.

Core

Always loaded, whatever SCREENCAST_TOOLSETS selects.

ToolWhat it does
get_media_infoProbe a media file with ffprobe and return duration, resolution, frame rate, codecs, container format, and size.
doctorCheck the setup: ffmpeg/ffprobe (FFmpeg 8+?), optional filters, capture devices, Windows OCR, settings, and enabled toolsets; problems says what is missing and how to fix it. Call on first use or when a tool reports a missing feature.
Capture

Record or screenshot the desktop, a monitor, a window, or a region. Every capture is an explicit tool call: nothing records on its own.

ToolWhat it does
start_recordingStart a background screen recording. Returns a session id; finalize it with stop_recording. Never auto-starts.
stop_recordingStop a recording gracefully so the file is finalized; returns the path and duration.
pause_recordingPause a recording; until resume_recording nothing is captured, and the gap is left out of the file, events, and markers.
resume_recordingResume a paused recording (same target and settings).
save_replaySave the last N seconds of a replay buffer (start_recording replayBufferSec) to an mp4; the buffer keeps running.
list_sessionsList all recording sessions (active and finished) with their status, target, output path, and whether the process is still alive.
get_sessionInspect a single recording session by id, including live status and whether its output file exists on disk.
read_eventsRead the input events (clicks, scroll, cursor, shortcuts, typing bursts) of a recording made with events: true, in video seconds and pixels; e.g. types: ['down'], then sample_frames there.
add_markerMark a labelled moment on a recording, live or at a second. Kept in the session and a sidecar; chapters and pipeline turn markers into chapters.
screenshotCapture one PNG of the screen, a monitor, a window, or a region, returned inline and by path.
list_audio_devicesList DirectShow audio devices and flag a likely loopback (Stereo Mix or a virtual-audio driver), for start_recording's audio.device.
list_video_devicesList DirectShow cameras for start_recording's webcam.device.
list_targetsList the desktop, monitors, and visible windows (topmost first, with capturability per backend). Each entry has a target string to pass as-is to capture tools; use it instead of guessing a title.
Watch

Turn footage into something a model can read: frames, contact sheets, diffs, OCR, and a searchable text timeline.

ToolWhat it does
review_recordingOpen a recording for a person to review: in MCP Apps clients an inline player to scrub, trim, and redact, then export; elsewhere just the video's details.
player_framesPreview frames for the review player: JPEGs on an even grid over the video plus frames at scene changes, with their real times. Used by the inline player; agents should use sample_frames or contact_sheet instead. *(app-only: called by the review player, not the agent)*
sample_framesSample PNG frames from a video (by fps, timestamps, or scene changes) and return the first few inline so the model can see what happened.
contact_sheetTile timestamped frames of a video into one image to see a whole recording at a glance (the cheapest first look).
screen_diffCompare two screenshots or frames: SSIM score, changed share, and changed boxes in b's pixels, to check a UI change happened only where expected.
wait_for_changeWait until part of the screen changes or settles, instead of guessing a sleep. Returns the elapsed time, changed regions (screenshot pixels; add origin for desktop), and the final state.
