Firefox reads its host manifests from ~/.mozilla/native-messaging-hosts (Mozilla/NativeMessagingHosts on macOS) and names the extension by its gecko id in allowed_extensions, not an origin. With the extension now asking for nativeMessaging, Firefox joins the router without a pairing code, as Chromium does. hanzo-tools-browser 0.5.14.
hanzo-tools-browser
Browser tools for Hanzo MCP: browser drives the user's own browser through
the Hanzo extension (headless Playwright when none is connected), playwright
is the same tool pinned to Playwright, and cdp sends a raw DevTools method.
Installation
pip install hanzo-tools-browser
pip install 'hanzo-tools-browser[playwright]' && playwright install chromium # headless fallback
The loop
browser(action="navigate", url="https://example.com")
browser(action="snapshot", interactive=True) # - button "Sign in" [ref=e2]
browser(action="click", selector="@e2")
browser(action="fill", selector="@e3", text="[email protected]")
browser(action="press", key="Enter")
browser(action="read", outline=True) # the page as markdown
browser(action="screenshot", annotate=True) # labels [N] = @eN, with a legend
selector takes a ref from the last snapshot or a CSS selector. A stale ref,
or a click on an element covered by a banner or modal, is refused with what to
do next.
Progressive surface
The schema carries the core actions: navigate, snapshot, click, fill, type,
press, read, screenshot, evaluate, wait, tabs, help. browser(action="help")
lists the rest by topic, and their parameters go in args:
browser(action="select", selector="@e4", args={"value": "Weekly"})
