Node.js MCP Server

Example Use Cases

• 1

  Perform simple numeric calculations via an exposed tool (e.g., add two numbers) without implementing custom parsing or validation.

• 2

  Retrieve local configuration or secrets (like an API key) through a controlled MCP tool rather than embedding them in prompts.

• 3

  Integrate custom tooling into Cursor AI or other LLM-based IDEs using MCP and a Stdio transport for local development workflows.

Description

This repository provides a minimal Model Context Protocol (MCP) server implemented in Node.js that exposes two example tools: an 'add' tool that sums two numbers and a 'getApiKey' tool that returns an API key from the environment. It demonstrates input validation with Zod and uses a Stdio transport for integration with development environments and Cursor AI. The project is intended as a boilerplate to show how to integrate custom tools into LLM-driven editors and agent workflows.
