Description
I'm Tyler - the solo operator of Quanta Intellect based in Portland, Oregon. I recently participated in Nous Research's Hermes Agent Hackathon, which is where this project was born.I've used agents extensively in my workflows for the better part of the last year - the biggest pain point was always the browser. Every tool out there assumes a human operator with automation bolted on. I wanted to flip that - make the agent the primary driver and give the human a supervisory role.Enter: Vessel Browser - an Electron-based browser with 40+ MCP-native tools, persistent sessions that survive restarts, semantic page context (agents get structured meaning, not raw HTML), and a supervisor sidepanel where you can watch and control exactly what the agent is doing.It works as an MCP server with any compatible harness, or use the built-in assistant with integrated chat and BYOK to 8+ providers including custom OAI compatible endpoints.Install with: npm i @quanta-intellect/vessel-browser

Could you build this?
Partial A basic Chromium wrapper with an agent-accessible API/supervision UI can be vibe-coded, but robust browser automation handling anti-bot protections, state isolation, and low-latency interactive human-in-the-loop control is challenging.
What it would actually take: Likely built on Electron or Playwright/CDP (Chrome DevTools Protocol) with a custom React frontend for supervision and session recording. The hard parts are handling bot detection evasion (Cloudflare, fingerprinting), managing persistent multi-tab state and sandboxed execution, and reliably exposing actionable DOM tree snapshots to LLMs without overwhelming token contexts.
