Copy-Paste Line Extractor MCP server

Copy-Paste MCP is a server implementation of the Model Context Protocol that provides a specialized tool for extracting specific lines from text content. It preserves exact formatting and doesn't modify the content during extraction, making it ideal for working with code snippets or specific sections of documents.

Installation

To install the Copy-Paste MCP server:

1. Clone the repository
2. Install dependencies:

npm install

Usage

Starting the MCP Server

To start the server, run:

npm start

This will launch the MCP server using the stdio transport, which can be connected to by compatible MCP clients.

Connecting to the Server

In an MCP-compatible client (such as Claude Desktop), add this server with:

• Name: Copy-Paste
• Command: node /path/to/copy-paste-mcp/dist/index.js
• Transport: stdio

Using the Extract Lines Tool

The server provides a single tool called extract-lines that can extract specific line ranges from text content.

Basic usage pattern:

Tool: extract-lines
Parameters:
  - text: "Your multi-line text content goes here\nSecond line\nThird line"
  - start_line: 1
  - end_line: 2

This will return the first two lines of the provided text.

Examples

Extract a Range of Lines

To extract lines 10-20 from a large text block:

Tool: extract-lines
Parameters:
  - text: [your text content with many lines]
  - start_line: 10
  - end_line: 20

Extract a Single Line

To extract just line 5:

Tool: extract-lines
Parameters:
  - text: [your text content]
  - start_line: 5
  - end_line: 5

Use Cases

This tool is particularly useful when you need to:

• Extract specific sections from large text blocks
• Copy exact line ranges from code or documentation
• Ensure precise content extraction without any alterations
• Integrate line extraction capabilities into AI workflows via MCP
• Work with specific portions of large documents

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "copy-paste" '{"command":"node","args":["/path/to/copy-paste-mcp/dist/index.js"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

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

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

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

3. Restart Claude Desktop for the changes to take effect
