MCP Resource Server
by cycle-sync-ai
This tutorial guides you through setting up a basic MCP (Model Context Protocol) server to expose read-only resources to Large Language Models (LLMs). It utilizes the `@modelcontextprotocol/sdk` to create a Node.js/TypeScript project.

What is MCP Resource Server?
An MCP (Model Context Protocol) server exposes read-only resources to Large Language Models (LLMs) through a standardized interface, allowing them to safely interact with external data and services like files, databases, and APIs.
How to use MCP Resource Server?
To use the server, you need to install Node.js, npm, and TypeScript. Then, initialize a project, install the @modelcontextprotocol/sdk, configure the package.json and tsconfig.json files, and create resources to expose data. The provided example demonstrates a simple greeting server.

What is Model Context Protocol (MCP)?
MCP is a standardized interface that allows LLMs to safely interact with external data and services.
What are MCP Resources?
What are MCP Resources?
Resources are read-only endpoints that expose content (text or binary) via a unique URI.
Why use MCP Resources?
Why use MCP Resources?
Resources enable LLMs to read files and databases, execute commands, access APIs, and interact with local tools with explicit user permission.
What are MCP Tools (Dynamic Actions)?
What are MCP Tools (Dynamic Actions)?
MCP Tools (also called dynamic actions) let you define custom functions that the LLM can call during a session, extending MCP’s capabilities beyond static resources.
