Hi, I'm Brian 👋

Product @ you.com. I build AI-agent infrastructure, MCP tools, and sharp macOS utilities for people who want their software to feel faster, cheaper, and more useful.

Right now my focus is split between YouAgent, AI-agent tooling for useful workflows with models, tools, memory, and context, and Superpaste, a macOS clipboard utility for faster paste workflows.

My work clusters around two ideas: making AI agents more capable and portable, and removing everyday friction from the software people use all day.

🔭 Current Focus

Project What I'm building
YouAgent AI-agent tooling for workflows that combine LLMs, tools, memory, and user context
Superpaste A macOS productivity app for smarter clipboard history, paste workflows, and text automation

📦 More open source

Project What it does
frugal Cost-optimized MCP server + proxy router that picks the cheapest model and toolchain for each task
MCP-Profiles Reusable, model-independent identity for AI agents via an MCP gateway
you.md Open protocol for portable user preferences and context across AI-assisted dev tools
PromptLens Lightweight prompt & agent evaluation tool
free-mail-merge Upload a CSV → get a mail-merged PDF
skills GTM skills for product builders — positioning, messaging & narrative
