mcp-wayland-clipboard

MCP server to write to the Wayland clipboard via wl-copy.

This Model Context Protocol (MCP) server allows AI models to copy text directly to your Wayland clipboard using the wl-copy command-line tool.

Prerequisites

• Node.js (v18 or higher)
• wl-copy installed and available in PATH (usually provided by the wl-clipboard package)

Installing wl-clipboard

On Arch Linux:

sudo pacman -S wl-clipboard

On Ubuntu/Debian:

sudo apt install wl-clipboard

Installation

npm install

Building

npm run build

This compiles the TypeScript source to JavaScript in the dist/ directory.

Usage

Starting the server

After building, you can start the server using:

npx mcp-wayland-clipboard

Or directly with Node:

node dist/index.js

Tool: copy_to_clipboard

The server provides a single tool called copy_to_clipboard that accepts a text parameter and copies it to your Wayland clipboard.

Parameters:

• text (string, required): The text to copy to the clipboard

Returns:

• Success: { success: true, message: "Text copied to clipboard" }
• Error: { success: false, error: "error message" }

Example Use Case

A common use case is asking an AI to generate formulas or code snippets and have them automatically copied to your clipboard. For example:

"Generate an Excel formula to sum cells A1 to A5 and copy it to my clipboard"

The AI can then call the copy_to_clipboard tool with the formula, and you can paste it directly into Excel.

Configuration for MCP Clients

Claude Desktop

Add the following to your Claude Desktop configuration file (typically located at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or ~/.config/Claude/claude_desktop_config.json on Linux):

{
  "mcpServers": {
    "wayland-clipboard": {
      "command": "npx",
      "args": ["-y", "mcp-wayland-clipboard"]
    }
  }
}

Or if you have the project installed locally:

{
  "mcpServers": {
    "wayland-clipboard": {
      "command": "node",
      "args": ["/path/to/mcp-wayland-clipboard/dist/index.js"]
    }
  }
}

Other MCP Clients

For other MCP clients, configure them to start the server using:

• Command: npx (or node if using local installation)
• Args: ["-y", "mcp-wayland-clipboard"] (or ["/path/to/dist/index.js"] for local)

Error Handling

The server will exit with an error code if wl-copy is not found in your PATH during startup. Make sure wl-clipboard is installed before running the server.
