Universal AI Agent Connector — by Corsen AI

Your signed-in web chats become a local OpenAI/Anthropic API; tabs you choose become MCP tools for AI agents. Local only.

Universal AI Agent Connector links the Chrome tabs you choose to the AI agents running on your own computer, through a small open-source companion app. Nothing goes through Corsen AI. TWO ROLES, CHOSEN BY YOU Each tab starts as Ignored: private, never read, never touched. From the toolbar button or the side panel, you give it one of two roles: • MCP — your agents can read the page as clean Markdown or as an accessibility tree with short element handles; click, type, select, scroll and navigate with real browser input; see console errors and failed requests; read the page's own JSON and GraphQL calls; and take a screenshot. • LLM — a chat site you are signed in to answers the requests of tools on your computer: each prompt is typed into the page and the answer read back as text, one request at a time. ONE-CLICK SETUP The companion app detects the MCP clients installed on your computer and writes their configuration for you, after a timestamped backup, with Unlink and Restore. The list of supported clients is in the README. PRIVATE BY DEFAULT, VISIBLE, REVERSIBLE • Chrome shows its "started debugging this browser" bar while a tab is controlled; cancel it and the tab is private again. • Panic stop detaches the extension from every page in one click. • Roles change only from your own interface, never by an agent. A request without the matching role fails; there is no fallback. • Passwords, one-time codes, card fields, hidden inputs, secret address parameters and credential headers are masked in the browser before anything leaves it. Screenshots are pixels and are not masked. • The extension talks only to the companion on 127.0.0.1, after a mutual HMAC pairing. No analytics, no telemetry, no remote code. REQUIREMENTS The companion app, free and open source (Apache-2.0), runs from its GitHub repository: Node.js 22 or newer and pnpm, then clone https://github.com/CorsenAI/universal-ai-agent-chrome-connector and run pnpm install, pnpm build and pnpm connector.
