Installation

Prerequisites

• Node.js v17 or higher

• Claude Desktop or GitHub Copilot or Other MCP supported clients

Setup

1. Clone the repository:

   git clone https://github.com/webreactiva-devs/mcp-character-counter.git
   cd mcp-character-counter

2. Install dependencies:

   npm install

Usage with Claude Desktop

1. Open your Claude Desktop configuration:

   macOS :

   code ~/Library/Application\ Support/Claude/claude_desktop_config.json

   Windows :

   code %APPDATA%\Claude\claude_desktop_config.json

2. Add the character counter to your MCP servers:

   {
     "mcpServers": {
       "character-counter": {
         "command": "node",
         "args": [
           "/ABSOLUTE/PATH/TO/webreactiva-devs/mcp-character-counter/mcp/character-counter.js"
         ]
       }
     }
   }

   Replace /ABSOLUTE/PATH/TO/ with the current path on your system.

3. Restart Claude Desktop to load the new MCP server.

4. Look for the hammer icon in the input box, which indicates available MCP tools.

5. Ask Claude to analyze text character counts, for example:

   • "Count the characters in this paragraph"

   • "How many numbers are in this text: '123 Main St, Apt 45B'?"

   • "Analyze the character composition of my email address"

Usage with GitHub Copilot

To use this MCP server with GitHub Copilot:

1. Make sure you have GitHub Copilot installed in your VS Code or other compatible IDE.

2. Open VS Code settings and search for "Copilot MCP".

3. Add a new MCP server configuration:

   "github.copilot.advanced": {
     "mcp.servers": [
       {
         "id": "character-counter",
         "name": "Character Counter",
         "transport": "stdio",
         "command": "node",
         "args": ["/path/to/webreactiva-devs/mcp-character-counter/mcp/character-counter.js"]
       }
     ]
   }

4. Restart VS Code.

5. You can now use the character counter with Copilot Chat commands like:

   • /mcp count-characters-in-text This is the text I want to analyze

Development

To modify or extend this MCP server:

1. Make your changes to character-counter.js

2. Restart the server in your MCP client

How It Works

This MCP server implements a single tool called count-characters-in-text that accepts text input and returns a detailed analysis of character composition. The server uses the Model Context Protocol to expose this functionality to compatible AI assistants.
