Character Counter MCP server

The MCP Character Counter is a lightweight Model Context Protocol server that provides detailed text analysis, counting total characters, characters without spaces, letters, numbers, and symbols with a detailed breakdown of character types.

Installation Requirements

Prerequisites

• Node.js v17 or higher
• An MCP compatible client such as Claude Desktop or GitHub Copilot

Setup Process

1. Clone the repository and navigate to the project directory:

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

2. Install the required dependencies:

   npm install
   

Using with Claude Desktop

Configuration

1. Open your Claude Desktop configuration file:

   On macOS:

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

   On Windows:

   code %APPDATA%\Claude\claude_desktop_config.json
   

2. Add the character counter to your MCP servers configuration:

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

   Make sure to replace /ABSOLUTE/PATH/TO/ with the actual path on your system.

3. Restart Claude Desktop for the new MCP server to be loaded.

Using the Tool

1. Look for the hammer icon in the Claude Desktop input box, indicating available MCP tools.

2. You can ask Claude to analyze text with prompts like:

   • "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"

Using with GitHub Copilot

Configuration

1. Ensure GitHub Copilot is 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 for the changes to take effect.

Using the Tool

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

Tool Functionality

The MCP server provides detailed analysis of text including:

• Total character count
• Character count excluding spaces
• Letter count (a-z, A-Z)
• Number count (0-9)
• Symbol count (non-alphanumeric characters)
• Detailed breakdown of character types

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

3. Restart Claude Desktop for the changes to take effect
