Overview

What is API & MCP Server Skeleton (ElysiaJS + Bun)?

A lightweight, high-performance API server built with ElysiaJS on the Bun runtime. It integrates Model Context Protocol (MCP) for context-aware AI interactions and includes WebSocket support for real-time communication. Designed for developers who need a fast, scalable server with MCP and WebSocket capabilities.

How to use API & MCP Server Skeleton (ElysiaJS + Bun)?

Clone the repository, install dependencies with bun install, and start the development server with bun run dev. Access the base API at http://localhost:3000. For WebSocket interactions, connect using a client like wscat to ws://localhost:3000 and send JSON events (e.g., prayer:schedule). For MCP discovery, use the endpoint http://localhost:3000/mcp/.well-known/mcp.json. Build for production with bun run build and start with bun start.

Frequently asked questions

What is MCP and how does this server support it?

MCP (Model Context Protocol) is a lightweight communication protocol for context-aware interactions with AI agents or applications. This server includes an MCP plugin registry and a discovery endpoint at `/.well-known/mcp.json`.

What are the runtime requirements?

Bun runtime v1.0+ is required. Node.js is optional for installing tools like `wscat`. A WebSocket client (Postman, wscat, etc.) is needed for WebSocket interactions.

What events are available by default?

Two example events are included: `prayer:schedule` (get prayer times for a city) and `registration:new` (register a new user with name, phone, and email).

How can I deploy this server to production?

Build the project with `bun run build` and start the production server with `bun start`. It can be deployed on platforms like Vercel, Railway, Fly.io, or any Bun-supported environment.

Is the documentation complete?

No, the documentation is not yet complete. Refer to the README and the separate `MCP_and_API.md` file for additional details.
