What you can do with it
Every example is a real prompt your AI can answer once AgentHub is installed.
Research, faster
Pull insight from any tab — articles, docs sites, search results, social profiles.
"Summarize this 60-page docs site." "Pull every job title from this LinkedIn profile into a table." "What's the pricing across all three competitor tabs I have open?"Forms, without copy-paste
Fill Salesforce, job applications, CRMs, contact forms — using data from another tab or a file.
"Fill this Salesforce lead with Jane's info from the tab next to me." "Apply to this job using my resume in tab 2." "Submit this contact form with the values from my CSV."Cross-tab orchestration
Your AI sees every tab, switches between them, and combines results into one answer.
"Find Jane's email in tab 1, her company's last funding round in tab 2, and fill them into the notes in tab 3."Drive your IDE from your browser
With MCP enabled, Claude Code or Cursor running in your terminal can ask the browser questions — and act on the answers.
"Open this URL in Chrome and fill the form with the test data from my repo." "What's on the user's screen right now?"One bridge. Every AI tool.
Add a new AI to your stack tomorrow without reinstalling anything in the browser.

Why AgentHub
Your real browser, your real data
Other "AI browsers" run inside a fresh Chromium — no cookies, no logins, no extensions. AgentHub uses your actual Chrome profile. Gmail is logged in. Slack is there. Saved passwords work.
One bridge, every tool
Most browser-for-AI extensions are locked to one AI provider. AgentHub speaks standard MCP — any MCP-compatible AI tool works without extension changes.
Your keys, your machine
Chat-tab API keys live in chrome.storage.local. They never leave your device because there is no backend.
Free, fully open source
No pro tier, no waitlist, no upsell. Read the code, audit the manifest, build it yourself.
Privacy-first defaults
Banking and email domains blocked by default. Real-time activity log shows every tool call. Per-tool permission toggles.
Multi-profile aware
Each Chrome profile gets a namespaced browser ID. Drive two profiles at once — an AI never confuses them.
Install in 60 seconds
No account. No waitlist. No backend to configure.
Install the extension
Add AgentHub from the Chrome Web Store. Edge Add-ons supported too — same build.
Open Chrome Web Store →Run the one-command setup
The installer detects your AI tools (Claude Code, Cursor, VS Code, etc.) and registers AgentHub with each automatically.
npx agenthub-setup@latest \ --extension-id <ID_FROM_SIDE_PANEL>
Ask your AI anything
Open your AI tool and ask it about the page you're on. Or open the AgentHub side panel and chat directly. That's it.
Requires Chrome 120+ or Edge 120+ · Node.js 18+ for the one-time install
FAQ
Is AgentHub free?
Yes, fully. No pro tier, no trial, no upsell. The setup installer (agenthub-setup) and the bridge binary are open source on GitHub.
Does my data go anywhere?
No. There is no AgentHub server. Browser ↔ AI communication is 100% local via Chrome's native messaging. API keys for the chat sidebar are stored in chrome.storage.local and never leave your machine. The activity log is local.
Which AI tools work with AgentHub?
Out of the box: Claude Code, Claude Desktop, Cursor, VS Code (Copilot or Continue), Windsurf, JetBrains IDEs, Zed, Continue.dev. Plus OpenAI, Anthropic, and Gemini direct from the chat sidebar. Any MCP-compatible AI tool works via the standard protocol.
Do I need an API key?
For the in-extension chat sidebar: yes, bring your own key for OpenAI, Anthropic, or Gemini. For the MCP bridge to external AI tools (Claude Code, Cursor, etc.): no — those tools handle their own auth. AgentHub just exposes the browser as a tool source for them.
Is this safe to install?
The extension code is open source. The native bridge is a small, audited binary that only talks to your local browser over Chrome's native messaging API — no network sockets, no open ports. Sensitive domains (banking, email) are blocked by default. Every tool can be disabled with a single toggle. Every AI action is logged.
What's different from other AI browser extensions?
Most AI browser extensions either (a) run a separate sandboxed Chromium without your cookies and logins, or (b) lock you to a single AI provider. AgentHub uses your real Chrome — so your Gmail, Slack, paid SaaS subscriptions all work — and is provider-agnostic. One install works with every major AI tool you use.
Does it work with multiple Chrome profiles?
Yes. Each profile gets a namespaced browser ID so an AI driving two profiles at once never confuses them. Tab IDs returned by list_tabs are scoped per profile.
What about Edge, Brave, Arc, Vivaldi?
Edge is fully supported — same build, the installer auto-detects and registers with Edge too. Brave, Arc, and Vivaldi receive the bridge's registry entries, and side-load builds work on any Chromium-based browser. The store listing ships through Chrome Web Store and Edge Add-ons.
