# McpMux

McpMux runs a local gateway so several AI clients can use the same MCP servers. It helps keep server settings and credentials in one place.

## What it does

McpMux is a desktop app for Windows, macOS, and Linux. It runs a local MCP gateway that Claude Code and other clients can connect to. Add servers from its built-in registry or configure your own; the app displays their tools, prompts, resources, and connection status.

Clients connect at `http://localhost:45818/mcp`. Credentials are encrypted in the operating system’s keychain, and OAuth tokens refresh automatically. Spaces keep servers, credentials, and permissions separate. You can map a folder to a Space and a Feature Set, but matching uses the exact path, so opening the project from a different path won’t match that mapping.

Feature Sets control which tools, prompts, and resources a client can access. Server changes sync to connected clients without a manual refresh. The app is built with Rust and Tauri 2.

## Install
