MarkuprPlus MCPサーバー

The Problem

Your coding agent can't see your screen. So you stop working and start transcribing: describe the layout bug in prose, take a screenshot, crop it, drag it into the right place, explain which part matters. You speak at 150 words per minute and type at 60, and the context leaks out on the way.

The Solution

MarkuprPlus is a Windows and macOS desktop app, with a CLI, MCP server, and GitHub Action for automated workflows. The desktop app lives in the Windows system tray or macOS menu bar. It records the exact window you point at, listens while you narrate, and lets you draw on the live screen without blocking your clicks. When you stop, it transcribes on-device, aligns your words to each mark, and writes a report your agent can act on — one finding per circle, each with its own annotated frame.

Windows: Ctrl+Shift+F → talk → Ctrl-drag → Ctrl+Shift+F → paste into your agent
macOS:   Cmd+Shift+F  → talk → Cmd-drag  → Cmd+Shift+F  → paste into your agent

The Loop

1. Press the capture shortcut and pick your target

Use Ctrl+Shift+F on Windows or Cmd+Shift+F on macOS.

The picker opens above every window. Whatever is under your cursor lights up — click it and the recorder locks onto that window alone, and stays locked through moves, resizes, and app switches. Region and full-display modes are one click away when a finding needs a wider frame.

If the window's identity or native geometry ever becomes ambiguous mid-session, capture stops rather than widening to whatever is behind it. You never ship a frame you didn't mean to share.

The capture controls live in one portrait popover, accessible from the Windows system tray or macOS menu bar.

2. Talk while you work

Keep clicking through your app as usual. MarkuprPlus records the window and your microphone together, then transcribes with Whisper on-device after you stop.

The picker, the drawing canvas, and the recording HUD are all excluded from screen capture at the OS level — nothing MarkuprPlus draws ends up in your video. Only your app does, plus the strokes you meant to leave.

3. Hold Ctrl (Windows) or Cmd (macOS) and draw

Hold the modifier key and drag to paint straight onto the live screen — freehand, circle, or highlight, in a colour you choose. Let go of the key and your next normal click both reaches the app underneath and saves that mark, clearing the canvas for the next one.

Three circles means three issues, not one screenshot with three scribbles on it. Each finding carries its own PNG, timestamp, tool, and colour.

4. Press the capture shortcut again to stop

Use Ctrl+Shift+F on Windows or Cmd+Shift+F on macOS.

Whisper runs, your narration is aligned to each mark, and the report is written to disk. The markdown path lands on your clipboard the moment it's ready — paste it straight into Claude Code, Codex, Cursor, or anything else that reads a file.

Everything for the session goes in one folder: the report, the screenshots, the session video, the narration audio, and the metadata.

Quick Start

Windows and macOS desktop app (recommended)

Download from markuprplus.com or the releases page. Choose the Windows installer (.exe) or the macOS disk image (.dmg) for Apple Silicon or Intel.

macOS install note: Direct downloads from GitHub Releases are signed, notarized, and stapled. If Gatekeeper rejects an artifact, use MarkuprPlus support so the release can be investigated.

1. Press Cmd+Shift+F (macOS) or Ctrl+Shift+F (Windows) and click the window you want.
2. Narrate what you see. Hold Cmd / Ctrl and drag to mark the live screen.
3. Release the key, then click normally — that saves the mark and clears the canvas. Repeat for every finding.
4. Press the hotkey again to stop. The report path is on your clipboard.

MCP server (for AI coding agents)

npx --yes --package markuprplus markuprplus-mcp

CLI (for recordings you already have)

npx markuprplus analyze ./recording.mov

Compatibility: the public package and commands are markuprplus and markuprplus-mcp. Existing .markuprx project files, storage paths, and app identifiers remain unchanged so upgrades keep their settings and sessions.

Optional companion for Mac App Store CLI integrations

The sandboxed Mac App Store app can use AI command-line tools already installed and signed in on your Mac through the optional MarkuprPlus CLI Bridge. Local Rules, Ollama, LM Studio, and Anthropic API do not require this companion.

Install and pair it from a Terminal:

npm install -g markuprplus
markuprplus bridge install     # installs and starts a per-user LaunchAgent
markuprplus bridge token       # paste this value in Settings → Advanced
markuprplus bridge status

The public npm package contains the same versioned CLI and MCP entry points used by the source release.

The service listens only on 127.0.0.1:49647, requires its random pairing token for every provider request, and accepts a fixed structured-report protocol rather than shell text. The App Store app does not run shell commands or launch external tools; the separately installed companion invokes only the provider selected in Settings.

Lifecycle and recovery commands:

markuprplus bridge start
markuprplus bridge stop
markuprplus bridge status
markuprplus bridge token
markuprplus bridge rotate-token
markuprplus bridge uninstall

Rotating the token requires pairing again. Uninstall removes the exact LaunchAgent and bridge configuration owned by MarkuprPlus; it does not uninstall your AI CLIs.

What Lands in Your Folder

One session, one directory:

originplayer-test-iphone-20260818-104731/
├── feedback-report.md          # the file you paste
├── feedback-summary.md         # counts and duration

A real, unedited finding from that session:

### MX-001

- **Timestamp:** 00:08
- **Tools:** freehand
- **Colors:** #ff3b30

#### User Comment

> So there's a search menu and over here by default, if there's been

#### Marked Evidence

![Marked issue MX-001](./screenshots/marked-issue-001.png)

Each finding carries more than pixels:

What travels with the issue	Example
Its own annotated PNG	screenshots/marked-issue-001.png
The narration at that moment	transcript-segment-0001 … 0002
How you marked it	freehand · #ff3b30
Where it came from	window:5976:0 · OriginPlayer Test iPhone · darwin
Cursor, active app, and focus hints	captured at the instant you drew
Trigger metadata	annotation, manual, pause, or voice-command

Marked issues are numbered MX-001…; items that come from narration alone are FB-001….

Every Surface

Local Transcription

On desktop startup, MarkuprPlus downloads the multilingual Whisper tiny model (~75 MB) in the background if no local model is installed. Existing models are reused. Download progress and retryable errors appear under Settings > Advanced > Local Transcription. Interrupted downloads resume on the next startup; offline or failed downloads do not block opening the app. Once downloaded, local transcription works without an internet connection.

Interface Language

The desktop interface defaults to English, including when upgrading from an installation that previously displayed Traditional Chinese automatically. Choose Settings > General > Language > Interface language to opt into Traditional Chinese or switch back to English. The preference is saved and applies immediately across open windows without restarting or interrupting a recording. Resetting General settings restores English.

Interface language is separate from transcription language. Feedback text, recordings, and generated reports are not translated by this setting.

To add another interface language, register its identifier and display name in src/shared/uiLanguage.ts and its translation catalog in src/renderer/i18n/catalogs.ts. English labels are the source and fallback for missing translations; mark user-content regions with translate="no".

Report Providers

Pick the model that turns a capture into a structured report. MarkuprPlus checks each one before you record and shows you what it actually found.

In the Mac App Store app, CLI providers use the optional local companion described above. Direct desktop builds invoke the same adapters inside the app. Both paths preserve Local Rules as the failure-safe report.

Provider	Kind	What it uses
Codex CLI	CLI	Your installed CLI or the Codex Mac app's bundled CLI and existing ChatGPT login, in a read-only ephemeral session
Claude Code CLI	CLI	The Claude Code CLI you're already signed in to
GitHub Copilot CLI	CLI	Copilot CLI 1.0.83+ with your existing GitHub login, in an isolated tool-free session
OpenCode	CLI	Your configured OpenCode provider, with a per-run agent that denies every tool action
Cursor Agent CLI	CLI	Cursor Agent in non-interactive, read-only Ask mode
Qwen Code	CLI	Qwen Code in safe, non-interactive plan mode with mutation tools excluded
Goose	CLI	Your configured Goose provider in tool-free chat mode, without profiles or session persistence
Amp	CLI	Your Amp login with an isolated default-deny tool policy
Kiro CLI	CLI	Kiro headless mode with only read and grep trusted
Aider	CLI	Your configured Aider model in dry-run, no-git mode
Ollama	Local	A model served on 127.0.0.1:11434 — nothing leaves the machine
LM Studio	Local	An LM Studio server on 127.0.0.1:1234
Anthropic API	Cloud	Your own key, stored in the system keychain and used for nothing else
Local rules	Zero setup	Deterministic report from transcript and marks alone, no credentials

Failure is safe by design. If the provider you picked errors out, the deterministic Local rules report is written anyway, and the popover names the provider and the reason. Your recording, audio, and marks were already on disk before analysis started. An explicit CLI choice never silently becomes an Anthropic call.

Codex CLI, GitHub Copilot CLI, and OpenCode can receive captured screenshots. Transcript-only CLI adapters reject screenshot-only sessions instead of inventing visual findings.

To use GitHub Copilot CLI, install or update copilot, run copilot login in Terminal, then select GitHub Copilot CLI in Report Settings and refresh providers. Leave the model blank to use your Copilot default, or enter a Copilot model ID. Discovery verifies the installed version; authentication is verified when a report runs. The optional CLI Bridge provides the same integration for the Mac App Store app.

Copilot receives the transcript over stdin and screenshots as attachments. Each report uses a temporary Copilot configuration that reuses only your login identity (credentials remain in the OS credential store) and default model, not your plugins, hooks, MCP servers, or saved permissions. All model tools and custom instructions are disabled. Temporary context is removed after success or failure. Environment-token authentication is also supported; plaintext credential fallbacks are not copied into the temporary configuration.

processing-trace.json records exactly what happened:

{
  "requestedProvider": "codex-cli",
  "actualProvider": "rules",
  "aiFallbackReason": "Codex analysis exited with status 1.",
  "aiEnhanced": false,
  "totalMs": 4220
}

Why MarkuprPlus

Evidence, not footage. A screen recording leaves your agent a video it can't watch and you a file you have to narrate twice. This gives you separate findings, one annotated frame each, the words you said at that timestamp, and the window and cursor context.

Local-first. Whisper runs on your device and Local rules needs no credentials. Cloud transcription and cloud models only run when you explicitly pick them. No account, no telemetry, no analytics.

It doesn't film itself. The picker, the drawing canvas, and the recording HUD are content-protected at the OS level. Your marks reach the report; the app's own chrome never reaches the video.

Fits your workflow. Windows and macOS desktop apps for daily capture, a CLI for scripts and CI, an MCP server for agents, and a GitHub Action for pull requests.

Open source. MIT licensed. Read it, fork it, ship it.

MCP Server

Give your agent eyes and ears. It can capture screenshots, record your screen with voice, and receive structured reports mid-conversation.

Connect GitHub Copilot CLI, the Claude Mac app, or Codex with the setup command:

npm install -g markuprplus
markuprplus integrate copilot
markuprplus integrate claude-desktop
markuprplus integrate codex

Run the command for each client you use, then restart that client. Claude setup covers both Chat and Code. Codex shares its configuration with its CLI. Add --dry-run to preview; existing settings and other servers are preserved, and changed files are backed up. An existing conflicting markuprplus entry requires --force. See client setup and capabilities for details.

For manual setup, Claude Code (~/.claude.json or project .mcp.json), Cursor, and Windsurf take the same shape:

{
  "mcpServers": {
    "MarkuprPlus": {
      "command": "npx",
      "args": ["--yes", "--package", "markuprplus", "markuprplus-mcp"]
    }
  }
}
