McpMux

mcpmux/mcp-mux

If you're running MCP servers across multiple AI clients (Cursor, Claude Desktop, VS Code, Windsurf), you're probably tired of duplicating config files and scattering API keys across plain-text JSON. McpMux is a local gateway that consolidates everything: configure your servers once in a desktop app, then point each client to localhost:45818. It handles routing, encrypts credentials in your OS keychain, refreshes OAuth tokens automatically, and lets you create workspaces with granular per-client permissions. Ships with a built-in registry of 100+ servers (GitHub, Slack, PostgreSQL, Docker, Notion, AWS). Add a server or rotate a key once and every connected client sees it instantly without config edits or restarts.

The Problem

Cursor, Claude Desktop, VS Code, Windsurf — they all support MCP, but each one needs its own config file. None of them talk to each other.
