# HyperIndex MCP Server in ReScript This is a Model Context Protocol (MCP) server implementation written in ReScript. It demonstrates best practices for: - Server initialization and configuration - Tool registration and management - Error handling and logging - Resource cleanup ## Prerequisites - Node.js 18+ - pnpm, npm, or yarn ## Getting Started 1. Install dependencies: ```bash pnpm install # or npm install # or yarn install ``` 2. Build the ReScript files: ```bash pnpm res:build # or npm run res:build # or yarn res:build ``` 3. Start the server: ```bash pnpm start # or npm start # or yarn start ``` ## Development For development with automatic rebuilding and the MCP inspector: ```bash pnpm dev # or npm run dev # or yarn dev ``` ## Project Structure - `src/MCP_SDK.res` - ReScript bindings for @modelcontextprotocol/sdk - `src/Index.res` - Main server entry point - `src/examples/` - Example tool implementations - `Calculator.res` - Simple calculator tool - `RestApi.res` - REST API interaction example ## Adding New Tools To add a new tool, follow the pattern in the example files: 1. Define a schema using rescript schema 2. Implement the tool handler function 3. Register the tool with the server in `Index.res`
