🪨 why use many token when few token do trick — Claude Code skill that cuts 65% of tokens by talking like caveman
macOS app for MCP servers and agent skills
MCP Bundler gives you a native macOS interface for managing local MCP servers, remote endpoints, and skill sources. It also runs in headless stdio mode so you can wire it into CLI and automation workflows.
Builders who manage MCP servers and agent skills across a macOS app and CLI workflows.
You can keep agent skills and MCP servers organized in one tool and run them from the desktop or automation scripts.
What it does
Manage local and remote MCP servers
The app provides a native macOS UI for adding, viewing, and operating local MCP servers and remote endpoints.
Headless stdio runner
It can run without the UI so CLI tools and automation workflows can talk to it over stdio.
Skill marketplace sources
It includes curated sources for browsing and installing skills.
OAuth and remote auth support
The codebase includes OAuth flows and remote authentication work for secured endpoints.
README
MCP Bundler (macOS)

Status
I decided to move the project from Paid software to open source thanks to Bags platform I need some time to prepare the code for open sourcing it and for allowing to download builds straight from the site and remove license gate. Bear with me, I need some hours for this.
Until then you can download app here: TEMP DOWNLOAD LINK
