Elysia MCP Starter
A starter template for building MCP (Model Context Protocol) servers using Elysia and Bun runtime.
This starter template is based on the elysia-mcp plugin, which provides comprehensive ElysiaJS integration for the Model Context Protocol with HTTP transport support.
Purpose
This repository provides a foundation for creating MCP servers that can be used with LLM clients like Claude Desktop, Cody, or other MCP-compatible applications. It demonstrates how to implement:
- Tools: Functions that can be called by LLMs (e.g., calculator)
- Prompts: Reusable prompt templates
- Resources: Dynamic data sources that can be accessed by LLMs

Getting Started
Option 1: Using Bun Create (Recommended)
# Create a new project from the starter template
bun create https://github.com/kerlos/elysia-mcp-starter my-mcp-project
# Navigate to the project
cd my-mcp-project
# Install dependencies
bun install
# Start development server
bun run dev
Option 2: Clone Repository
-
Clone or use this template:
git clone https://github.com/kerlos/elysia-mcp-starter.git cd elysia-mcp-starter -
Install dependencies:
bun install -
Start the development server:
bun run dev
The MCP server will be available at:
- Server:
http://localhost:3000 - MCP endpoint:
http://localhost:3000/mcp
Development
- Development server:
bun run dev(with auto-reload) - Production server:
bun run start - Inspect MCP server:
bun run inspect(opens MCP inspector)
Adding New Components
Tools
Add new tools in src/tools/ and register them in src/index.ts:
import { registerYourTool } from './tools/your-tool';
// ... in setupServer:
registerYourTool(server);
Prompts
Add new prompts in src/prompts/ and register them in src/index.ts:
import { registerYourPrompt } from './prompts/your-prompt';
// ... in setupServer:
registerYourPrompt(server);
Resources
Add new resources in src/resources/ and register them in src/index.ts:
import { registerYourResource } from './resources/your-resource';
// ... in setupServer:
registerYourResource(server);
Using with LLM Clients
Configure your MCP-compatible client to connect to http://localhost:3000/mcp to access the tools, prompts, and resources provided by this server.
MCP Client Configuration
Add the following configuration to your MCP client's configuration file:
For Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json):
{
"mcpServers": {
"elysia-mcp-starter": {
"type": "http",
"url": "http://localhost:3000/mcp"
}
}
}
For Cursor (~/.cursor/mcp.json):
{
"mcpServers": {
"elysia-mcp-starter": {
"type": "http",
"url": "http://localhost:3000/mcp"
}
}
}
For Cody (VS Code settings):
{
"cody.experimental.mcp.servers": {
"elysia-mcp-starter": {
"type": "http",
"url": "http://localhost:3000/mcp"
}
}
}
Replace "elysia-mcp-starter" with your preferred server name and update the URL if you're running on a different port.
