Provides the runtime environment for the MCP server, enabling server-side execution of the tools and communication via standard I/O.
Supports package management for the MCP server, allowing easy installation of dependencies and execution of build scripts.
Serves as the foundation for building custom MCP tools, providing type safety and structure for implementing tools that can be integrated with AI systems.
Alternative package manager for the MCP server, offering another option for dependency management and script execution.
Used for schema validation to define and validate tool inputs, ensuring properly formatted data is provided to the MCP tools.
MCP TypeScript Simple Template
A simple TypeScript template for building Model Context Protocol (MCP) servers. This project provides a foundation for creating custom MCP tools that can be integrated with AI systems.
Overview
This template implements a basic MCP server with a sample BMI calculator tool. It demonstrates how to:
Set up an MCP server in TypeScript
Define and implement MCP tools with input validation using Zod
Connect the server to standard I/O for communication
