MCP Server Experiments Rescript

🚀 Implementing a HyperIndex MCP Server in ReScript

This project is an implementation of a Model Context Protocol (MCP) server written in ReScript. It demonstrates best practices in the following areas:

• Server initialization and configuration
• Tool registration and management
• Error handling and logging
• Resource cleanup

🚀 Quick Start

Prerequisites

• Node.js version 18 or higher
• A package manager such as pnpm, npm, or yarn

Installation Steps

1. Install dependencies:

   pnpm install
   # Or
   npm install
   # Or
   yarn install
   

2. Build ReScript files:

   pnpm res:build
   # Or
   npm run res:build
   # Or
   yarn res:build
   

3. Start the server:

   pnpm start
   # Or
   npm start
   # Or
   yarn start
   

💻 Usage Examples

Development Mode

Use the development mode (with automatic building and MCP debugging tools):

pnpm dev
# Or
npm run dev
# Or
yarn dev

📚 Documentation

Project Structure

• src/MCP_SDK.res - ReScript bindings for @modelcontextprotocol/sdk
• src/Index.res - The main entry file for the server
• src/examples/ - Examples of tool implementations
  • Calculator.res - A simple calculator tool
  • RestApi.res - An example of interacting with a REST API

Adding New Tools

To add a new tool, follow the pattern in the example files:

1. Define the schema using the rescript schema.
2. Implement the tool handling function.
3. Register the tool with the server in Index.res.
