How do I install AgentHub?
Install the AgentHub extension from the Chrome Web Store, then run npx agenthub-setup@latest --extension-id <ID> in a terminal. The extension ID is shown in AgentHub's side panel after install. The installer auto-detects your AI tools (Claude Code, Cursor, VS Code, etc.) and registers AgentHub with each.
The MCP bridge says "disconnected" in the side panel.
Run npx agenthub-setup@latest --extension-id <ID> again — it re-registers the native messaging host. Then reload the extension in chrome://extensions. The bridge auto-reconnects within a few seconds. If it still won't connect, restart Chrome.
My AI tool doesn't see the AgentHub tools.
Make sure the AI tool was running when you ran agenthub-setup, then restart it. Each AI client (Claude Code, Cursor, VS Code, etc.) loads MCP servers at startup — a restart picks up the new registration.
Where is my OpenAI / Anthropic / Gemini API key stored?
In chrome.storage.local on your device. It never leaves your browser. There is no AgentHub backend to receive it. See the Privacy Policy for details.
Can I use AgentHub on banking or email sites?
Banking and email domains are blocked by default for safety. You can remove a site from the blocklist in Settings if you understand the risk — the AI will then have full read/write access to that domain.
My API key is rejected even though it works in OpenAI's playground.
Three usual causes: (1) the key was created on a different OpenAI organization than the one with billing, (2) the model you selected isn't available on your tier, (3) you exceeded the rate limit. Try a different model from the dropdown, then check your OpenAI usage dashboard.
Form filling didn't work on a specific page.
AgentHub handles React, Vue, Lit, plain HTML, and shadow DOM via the debugger permission. If a form still won't fill, the page is likely using a custom widget AgentHub doesn't recognize yet — please use the contact form above with the URL (or a public test page) and we'll add support.
Does AgentHub work in Edge, Brave, or Arc?
Edge: 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.
Where can I read the source code?
GitHub: github.com/irmasemma/AIBrowserCopilot. Issues and feature requests: github.com/irmasemma/AIBrowserCopilot/issues.
Before contacting support, try these steps:
chrome://extensions and make sure AgentHub is enabled and up to datenpx agenthub-setup@latest --extension-id <ID> to refresh the native messaging registration
