a light weight version of mcp sdk inspired by official model context protocol sdk, NOW focus on sse only no stdio
a light weight version of mcp sdk inspired by official model context protocol sdk, NOW focus on sse only no stdio. That is what the lite mcp sdk mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
This repo now includes 2 parts: 1. Lite mcp sdk for javascript 2. Lite mcp for javascript
Installation goes through your MCP client rather than a global install: point it at litemcpjs on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
The server publishes 10 tools. What each one is for:
Feature — mcp-official-sdkValidation — zodTransport — stdio or SSELanguage — typescriptAuth — includedDocumentation — vagueArchitecture — complexInstallation — The Installation tool exposed by this serverServer — //or module import import { Server, SSEServerTransport } from "lite-mcp-sdk";Client — // 1. Define the client let client = new Client( { name: "fastmcp-client", version: "0.1.0" }, { capabilities: { sampling: {}, roots: { listChangedPlenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Lite MCP Sdk's toolset — Feature, Validation, Transport and 7 more — is a fair guide to whether it matches your workflow. It is maintained by S2thend; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
