How to Set Up and Use Litemcp
LiteMCP is a TypeScript framework for building Model Context Protocol servers with minimal boilerplate, offering a clean API for registering tools, resources, and prompt templates alongside built-in logging and support for both stdio and SSE transport modes. Developers use it to rapidly prototype and ship custom MCP servers in TypeScript without manually implementing the MCP protocol wire format. Note that the project is deprecated in favor of the official MCP TypeScript SDK, but the patterns and existing servers built on it remain functional.
Prerequisites
- Node.js 18 or later
- npm or a compatible package manager
- TypeScript knowledge for building custom servers
- Zod library (installed alongside litemcp for schema validation)
- An MCP-compatible client such as Claude Desktop or Cursor to test the server
Install litemcp and zod
Add litemcp and zod as dependencies in your TypeScript project. Zod is required for defining tool parameter schemas.
npm install litemcp zodCreate your MCP server file
Create a server.ts (or server.js) file and define your MCP server with tools, resources, or prompts using the LiteMCP API.
import { LiteMCP } from "litemcp";
import { z } from "zod";
const server = new LiteMCP("my-server", "1.0.0");
server.addTool({
name: "greet",
description: "Greet a user by name",
parameters: z.object({ name: z.string() }),
execute: async (args) => `Hello, ${args.name}!`,
});
server.start();Test the server with the litemcp dev CLI
Use the built-in litemcp dev command to launch an interactive test session that lets you call your tools and inspect results without a full MCP client.
npx litemcp dev server.jsConfigure your MCP client to use the server
Add your LiteMCP server to your client's MCP configuration. For a compiled TypeScript server, point to the built JavaScript file.
{
"mcpServers": {
"my-litemcp-server": {
"command": "node",
"args": ["/absolute/path/to/your/server.js"]
}
}
}(Optional) Enable SSE transport mode
To expose your server over HTTP/SSE instead of stdio, configure the transport type when starting the server. The default SSE port is 8080.
server.start({
transportType: "sse",
sse: {
endpoint: "/sse",
port: 8080,
},
});Litemcp Examples
Client configuration (stdio, compiled JS server)
MCP client config for a server built with LiteMCP, compiled to JavaScript and run with Node.js.
{
"mcpServers": {
"my-litemcp-server": {
"command": "node",
"args": ["/absolute/path/to/your/dist/server.js"]
}
}
}Prompts to try
Example prompts for a server built with LiteMCP that exposes custom tools. Replace with prompts that match the tools you implement.
- "Call the greet tool with my name"
- "List all available tools on the my-litemcp-server MCP server"
- "Use the add tool to calculate 42 + 58"
- "Fetch the resource at resource://my-data/items"
- "Use the summarize prompt template with this text: [your text here]"Troubleshooting Litemcp
npx litemcp dev fails with 'Cannot find module' errors
Ensure litemcp and zod are installed in the project directory (npm install litemcp zod). If your server is TypeScript, compile it first with tsc or use ts-node: npx ts-node server.ts. Pass the compiled .js file to litemcp dev.
MCP client cannot connect to the stdio server
Verify the path to your server.js file in the MCP config is absolute and correct. Test by running node /path/to/server.js directly in a terminal — it should start without errors. Ensure Node.js is in the PATH that your MCP client uses.
LiteMCP is deprecated — should I still use it?
For new projects, use the official MCP TypeScript SDK (@modelcontextprotocol/sdk) which is actively maintained by Anthropic. LiteMCP servers continue to work but will not receive updates. Existing code can be migrated by replacing the LiteMCP API calls with equivalent SDK patterns.
