What it does

McpMux is a local MCP gateway that solves the problem of duplicated configurations. Instead of managing separate config files for Cursor, Claude Desktop, VS Code, and Windsurf, you configure your servers once in McpMux and connect every AI client to a single local endpoint.

Tools

McpMux acts as a multiplexer, exposing the tools, prompts, and resources of all connected upstream MCP servers. It provides a GUI for server discovery, installation, and credential management using the OS keychain for security.

Installation

Install the McpMux desktop app from mcpmux.com, then add the following to your AI client's MCP config:

{
  "mcpServers": {
    "mcpmux": {
      "type": "http",
      "url": "http://localhost:45818/mcp"
    }
  }
}
