SWIFT EVOLUTION

WHAT I'M WORKING ON

New app: MCP Beast

Quite the surprise, probably. I didn't start on this app until the last newsletter went out. It's crazy how fast we can move these days.

This new Mac app is called MCP Beast, and it is an answer to an issue I'm having myself: adding and managing MCPs across multiple locations.

The solution is simple:

  • A centralized place to add all your MCPs
  • Connecting all your apps (Cursor, Codex, ChatGPT, Claude) to a single MCP: MCP Beast

The Mac app allows you to connect to all your MCPs via localhost and optimizes delivery to reduce context (e.g., returning only the tools you really need for the MCP).

Secondly, I've often found myself sitting on the couch during a creative moment when I needed an MCP. Sometimes it's a public MCP, but sometimes it's an MCP like Astro's for App Store Optimization that only runs locally on my Mac. MCP Beast allows you to publish your MCP on your local network, accessible via Wi-Fi, or even broadcast it to the public web so you can access it from anywhere.

The app is now available in the Mac App Store and the landing page can be checked out here.
