README

⭐ Featured on reddit: I made an MCP server that tells you if a number is even or not

is-even-mcp is a popular MCP library, which climbed to the all-time high of the /r/mcp for a number of months.

Essentially, it's an MCP server, a connector for AI agents, that helps them do complex math such as determining if a number is even, or if it is not even.

Introducing is-even-mcp

Helps you know whether a number is even or not.

This is a TypeScript-based MCP server that implements the evenness algorithm in a way accessible to AI agents.

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "is-even": {
      "command": "/path/to/is-even/build/index.js"
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
