mTarsier Open-source platform for managing MCP servers and clients.

Desktop app that auto-detects every AI client on your machine — Claude Desktop, Cursor, Windsurf, VS Code and more.

Manage all your MCP server configs in one place, install from the marketplace, and back up with one click. macOS, Windows & Linux.


The problem we kept hitting: Every AI client — Claude Desktop, Cursor, Windsurf, VS Code — has its own config file. Adding, removing, or enabling an MCP server means hunting down JSON files, switching between apps, and praying nothing breaks. It's chaos, and it kills momentum.

The problem isn't new — the community has been screaming about it:

Garry Tan (YC President): "MCP sucks honestly. Toggling it on and off, the auth sucks." A dev on X: "why does every AI client handle MCP config differently?? I just want ONE place." Hacker News has a 145-point thread: "MCP is a fad."

But here's the other side:

OpenAI, Google DeepMind, AWS, Microsoft, and Cloudflare all backed MCP. Downloads went from 100K to 8 million in 6 months. Fortune 500s are deploying it. The Linux Foundation now governs it. Jensen Huang called it something that "completely revolutionized the AI landscape."

MCP isn't a fad. The protocol won. The tooling just hasn't caught up — yet. That's what mTarsier is here to fix.
