概要

What is Screenshot Server?

Screenshot Server is an MCP (Modular Communication Protocol) server that captures screenshots and saves them to a file path specified by the client, enabling AI assistants or other processes to access the screenshot via its file path.

How to use Screenshot Server?

Deploy the server on Windows (required for capturing the Windows screen), install dependencies with uv sync, and configure the MCP host to launch it (e.g., via PowerShell in WSL). Use the provided tools: save_screenshot_to_host_workspace, take_screenshot_and_return_path, or take_screenshot_path.

Key features of Screenshot Server

Captures the entire Windows screen.
Saves screenshots to a file path specified by the client.
Converts WSL paths to Windows UNC paths automatically.
Provides three tools with different save destinations.
Logs server activity to server.log.

Use cases of Screenshot Server

An AI assistant in WSL captures a screenshot and saves it directly into its workspace.
A process saves a screenshot to a fixed images/ directory and returns the absolute path.
A user saves a screenshot to an arbitrary Windows or UNC path for external processing.

よくある質問

What is the recommended workflow for WSL2?

The recommended workflow uses `save_screenshot_to_host_workspace` with WSL workspace path; the server converts it to a UNC path, saves the screenshot, and returns `"success"`.

What tools does Screenshot Server provide?

Three tools: `save_screenshot_to_host_workspace` (recommended), `take_screenshot_and_return_path`, and `take_screenshot_path`.

Where does Screenshot Server save screenshots?

It saves to a path specified by the client: either the host’s workspace (via UNC path conversion), a local `images/` directory, or an arbitrary directory given as a Windows or UNC path.

What are the runtime requirements?

Python 3.x, dependencies `mcp[cli]>=1.4.1`, `pyautogui`, and `Pillow`, installed via `uv sync`. The server must run directly on Windows to capture the screen.
