From the repository
Install Node.js v17 or higher, clone the repository, run npm install, then add a server configuration to your MCP client (e.g., Claude Desktop’s claude_desktop_config.json or VS Code’s Copilot MCP settings). After restarting the client, ask the AI to analyze text, for example: “Count the characters in this paragraph” or “How many numbers are in this text: ‘123 Main St, Apt 45B’?”.

}MCP Character Counter
A lightweight Model Context Protocol (MCP) server that provides detailed character analysis for text. This tool counts total characters, characters without spaces, letters, numbers, and symbols.
Features
- Count total characters in text
- Count characters excluding spaces
- Count letters (a-z, A-Z)
- Count numbers (0-9)
- Count symbols (non-alphanumeric characters)
- Detailed breakdown of character types
Installation
Prerequisites
- Node.js v17 or higher
- Claude Desktop or GitHub Copilot or Other MCP compatible clientes
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 actual 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.
