Description

This MCP server exposes a tool named `count-characters-in-text` that accepts text and returns a detailed breakdown of character composition (total chars, chars without spaces, letters, digits, symbols). It is implemented in Node.js and designed to be integrated with MCP-compatible clients like Claude Desktop and GitHub Copilot. The tool is useful for quick validation, text analytics, and model context management where character counts matter. Distributed under an MIT license, it is easy to install and run locally.
