概要

What is MCP Character Counter?

MCP Character Counter is a lightweight Model Context Protocol (MCP) server that provides detailed character analysis for text. It counts total characters, characters without spaces, letters, numbers, and symbols. It is intended for developers using MCP‑compatible AI assistants such as Claude Desktop or GitHub Copilot.

How to use MCP Character Counter?

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’?”.
