description: Use when the user wants Oracle beside a logged-in Chrome profile. Use the per-tab Oracle Sidecar grant, never CDP.

# Chrome profile browser

Use Oracle Sidecar for authenticated browser context. The native-host installer currently supports Chrome, Brave, Chromium, and Edge profiles on macOS and Linux. It is loaded separately into whichever supported browser profile the user chooses. Do not claim Windows native-host support.

## Boundary

- The user clicks the grant chip for one exact tab ID and origin.
- The grant lives in `chrome.storage.session` and disappears on browser restart or tab close.
- A navigation to another origin requires a new grant.
- The extension returns a bounded read-only tab context: title, URL, description, selection, and visible text.
- It does not export cookies, credentials, browser storage, or a CDP endpoint.
- Extension chat is prepare-only. Signing and broadcast are structurally absent.

Do not claim the companion can click, type, submit, or automate the granted page. The user remains the browser operator. Use `browser_exec` for isolated public-page interaction.

Install from Oracle's Browser and web tools documentation. On macOS or Linux, run `npm run install:host` from the extracted bundle, load the unpacked `extension/` directory in the chosen browser profile, restart the browser, and verify the Sidecar connection indicator. The release bundle does not include a doctor command.
