Overview

Description from the maker (original English)

Windows screen capture MCP server with display, region, and active-window capture tools.

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

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: CAPTURE_SCREEN_DEFAULT_DISPLAY, CAPTURE_SCREEN_OUTPUT_DIR, CAPTURE_SCREEN_HIDE_FOREGROUND_WINDOWS_TERMINAL

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "capture-screen": {
      "command": "dnx",
      "args": [
        "CaptureScreenMcp",
        "--yes"
      ],
      "env": {
        "CAPTURE_SCREEN_DEFAULT_DISPLAY": "your-value",
        "CAPTURE_SCREEN_OUTPUT_DIR": "your-value",
        "CAPTURE_SCREEN_HIDE_FOREGROUND_WINDOWS_TERMINAL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add capture-screen --env CAPTURE_SCREEN_DEFAULT_DISPLAY=your-value --env CAPTURE_SCREEN_OUTPUT_DIR=your-value --env CAPTURE_SCREEN_HIDE_FOREGROUND_WINDOWS_TERMINAL=your-value -- dnx CaptureScreenMcp --yes

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "capture-screen": {
      "command": "dnx",
      "args": [
        "CaptureScreenMcp",
        "--yes"
      ],
      "env": {
        "CAPTURE_SCREEN_DEFAULT_DISPLAY": "your-value",
        "CAPTURE_SCREEN_OUTPUT_DIR": "your-value",
        "CAPTURE_SCREEN_HIDE_FOREGROUND_WINDOWS_TERMINAL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "capture-screen": {
      "type": "stdio",
      "command": "dnx",
      "args": [
        "CaptureScreenMcp",
        "--yes"
      ],
      "env": {
        "CAPTURE_SCREEN_DEFAULT_DISPLAY": "your-value",
        "CAPTURE_SCREEN_OUTPUT_DIR": "your-value",
        "CAPTURE_SCREEN_HIDE_FOREGROUND_WINDOWS_TERMINAL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • CAPTURE_SCREEN_DEFAULT_DISPLAY env
    Default display selector when capture_display display argument is omitted.
  • CAPTURE_SCREEN_OUTPUT_DIR env
    Default output directory for PNG captures. Default is C:\capture_screen.
  • CAPTURE_SCREEN_HIDE_FOREGROUND_WINDOWS_TERMINAL env
    Set 0/false/off to disable temporary hiding of overlapping Windows Terminal windows during capture.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Capture Screen 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 (1.0.5) reached the registry 7 months ago.

Which apps can use it?

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

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, sync. labs

CaptureScreenMCP

Windows 向けのローカル実行型 MCP サーバーです(stdio transport)。 C# / .NET 10 の .NET tool として NuGet.org に公開しており、画面キャプチャとキャプチャ画像削除ツールを提供します。

  • NuGet: CaptureScreenMcp
  • MCP Registry name: io.github.ochtum/capture-screen
  • NuGet package ID: CaptureScreenMcp
  • Tool command: capture-screen-mcp

何ができるか

  • 接続ディスプレイ情報の取得
  • デスクトップ全体、指定ディスプレイ、指定領域、アクティブウィンドウの PNG キャプチャ
  • 出力先ディレクトリ内のキャプチャ画像一括削除
  • 日付/日時範囲でのキャプチャ画像削除
  • capture_screen / capture_display / capture_region 実行時に、撮影領域に重なった Windows Terminal を一時的に非表示化(既定で有効)

利用可能な Tools

  • list_displays()
  • capture_screen(outputPath?: string)
  • capture_display(display?: int | string, outputPath?: string)
  • capture_region(x: int, y: int, width: int, height: int, outputPath?: string)
  • capture_active_window(outputPath?: string)
  • delete_all_capture_images()
  • delete_capture_images_by_datetime(targetDate?: string, startDatetime?: string, endDatetime?: string)

必要環境

  • Windows
  • .NET 10 SDK
  • NuGet から MCP サーバーとして起動する場合は dnx を使用します。
  • 開発中にソースから起動する場合は dotnet run を使用します。

環境変数

  • CAPTURE_SCREEN_DEFAULT_DISPLAY
  • capture_display で display 省略時の既定値
  • 例: primary, left, right, プライマリ, 左, 右, 2
  • CAPTURE_SCREEN_OUTPUT_DIR
  • 保存先ディレクトリ(既定: C:\capture_screen)
  • CAPTURE_SCREEN_HIDE_FOREGROUND_WINDOWS_TERMINAL
  • 1/true/on で有効、0/false/off で無効
  • 既定は有効

NuGet から利用する

NuGet.org の公開済みパッケージを MCP クライアントから起動する場合は、dnx で CaptureScreenMcp を実行します。

{

"servers": { "capture-screen": { "type": "stdio", "command": "dnx", "args": ["CaptureScreenMcp@1.0.5", "--yes"], "env": { "CAPTURE_SCREEN_OUTPUT_DIR": "C:\\capture_screen", "CAPTURE_SCREEN_DEFAULT_DISPLAY": "primary", "CAPTURE_SCREEN_HIDE_FOREGROUND_WINDOWS_TERMINAL": "1" } } } }

通常の .NET tool としてインストールして起動することもできます。

dotnet tool install --global CaptureScreenMcp --version 1.0.5

capture-screen-mcp

ソースから開発実行する

ビルド
dotnet restore

dotnet build

MCP サーバー起動(stdio)
dotnet run --project src

開発中にソースツリーを直接参照する場合の接続設定例です。

{

"servers": { "capture-screen": { "type": "stdio", "command": "dotnet", "args": ["run", "--project", "src"], "env": { "CAPTURE_SCREEN_OUTPUT_DIR": "C:\\capture_screen", "CAPTURE_SCREEN_DEFAULT_DISPLAY": "primary", "CAPTURE_SCREEN_HIDE_FOREGROUND_WINDOWS_TERMINAL": "1" } } } }

公開手順

NuGet.org へ公開する
  1. src/CaptureScreenMcp.csproj の を更新します。
  2. .mcp/server.json のトップレベル version と packages[0].version を同じバージョンに更新します。
  3. dotnet pack src/CaptureScreenMcp.csproj -c Release
  4. dotnet nuget push src/bin/Release/*.nupkg --api-key --source https://api.nuget.org/v3/index.json

このパッケージは NuGet MCP サーバーとして認識されるため、以下を含めています。

  • .mcp/server.json
  • README.md の コメント
  • PackageIcon に指定した icon.png
  • McpServer package type
  • .NET tool 設定(PackAsTool / ToolCommandName)
MCP Registry へ公開する

NuGet.org への公開だけでは、registry.modelcontextprotocol.io には自動掲載されません。 NuGet.org のパッケージ検証が完了してから、MCP Publisher で .mcp/server.json を公開します。

mcp-publisher login github

mcp-publisher publish .mcp/server.json

server.json の name と、NuGet パッケージに含まれる README.md の mcp-name は一致している必要があります。 また、packages[0].version は mcp-name が一致する NuGet パッケージのバージョンを指している必要があります。

権限と注意点

  • 本サーバーはローカル実行型です。MCP クライアントと同じユーザー権限で動作します。
  • 画面キャプチャ結果はローカルファイルとして保存されます。機密情報が映り込む可能性に注意してください。
  • 画像削除ツールは CAPTURE_SCREEN_OUTPUT_DIR 直下の画像ファイルを削除します。
  • Windows 専用実装です。Windows 以外で実行するとエラーになります。

マニフェスト

  • 開発実行用: server.json
  • NuGet MCP 公開用: .mcp/server.json
