Demonstrates building an MCP server in Node.js with custom tools for seamless integration with AI-assisted environments.
This project demonstrates an MCP server implemented in JavaScript using Node.js. It defines two tools: add, which takes two numeric inputs and returns their sum, and getApiKey, which retrieves the API key from the API_KEY environment variable. It also provides a predefined prompt add_numbers that allows AI models to infer the usage of the addition tool.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
