# What is Harbor?

> Universal MCP Hub — discover, install, run, and sync MCP servers across every host.

Harbor is a desktop app and CLI that manages [MCP (Model Context Protocol)](https://modelcontextprotocol.io) servers from a single place. Instead of editing JSON and TOML configs by hand across every host, you dock servers once and Harbor syncs them everywhere.

## Why Harbor?

Every AI-powered development tool — Claude Code, Claude Desktop, Codex, VS Code, Cursor — has its own config file format for MCP servers. Adding a new server means editing multiple files, copying API keys around, and hoping nothing breaks.

Harbor fixes this. You configure your servers once, and Harbor handles the rest.
