Google Webmcp

Connect to Google Search and Gemini through the built-in local-mcp Google adapter and one fixed UXC link. Use when the user wants to run Google searches, chat with Gemini, or download generated Gemini images from an authenticated browser profile.

Use this skill to operate Google Search and Gemini through the built-in --site google bridge preset in @webmcp-bridge/local-mcp.

For generic bridge setup patterns or non-Google sites, switch to $webmcp-bridge.

Prerequisites

• uxc is installed and available in PATH.
• npx is installed and available in PATH.
• Network access to https://www.google.com and https://gemini.google.com.
• On a fresh machine, or under an isolated HOME, install Playwright browsers first with npx playwright install.
• Gemini is auth-sensitive. Expect bootstrap_then_attach behavior when the profile is not signed in yet.

Core Workflow

1. Ensure the fixed Google link exists:
   • command -v google-webmcp-cli
   • if missing or pointed at the wrong profile, run skills/google-webmcp/scripts/ensure-links.sh
2. Inspect the bridge and tool schema before calling tools:
   • google-webmcp-cli -h
   • google-webmcp-cli search.web -h
   • google-webmcp-cli gemini.chat -h
   • google-webmcp-cli gemini.image.download -h
3. Check authentication state first when Gemini may need sign-in:
   • google-webmcp-cli bridge.session.status
   • google-webmcp-cli auth.get
   • if the session is not ready, start bootstrap or switch to headed:
     • google-webmcp-cli bridge.session.bootstrap
     • google-webmcp-cli bridge.session.mode.set '{"mode":"headed"}'
     • google-webmcp-cli bridge.open
4. Use search tools for public search results:
   • google-webmcp-cli search.web '{"query":"playwright browser automation","limit":10}'
   • google-webmcp-cli page.get
5. Use Gemini through the same authenticated browser profile:
   • text: google-webmcp-cli gemini.chat '{"prompt":"Summarize these results","mode":"text","timeoutMs":180000}'
   • image: google-webmcp-cli gemini.chat '{"prompt":"a watercolor fox reading documentation","mode":"image","timeoutMs":300000}'
   • download current visible images: google-webmcp-cli gemini.image.download '{"limit":4,"timeoutMs":120000}'
6. Use debug and navigation helpers only when necessary:
   • google-webmcp-cli page.navigate '{"url":"https://gemini.google.com/app"}'
   • google-webmcp-cli page.inspect '{"limit":20}'
7. Parse JSON output only:
   • success path: .ok == true, consume .data
   • failure path: .ok == false, inspect .error.code and .error.message

Default Target

The built-in preset uses:

--site google

The default profile path is:

~/.uxc/webmcp-profile/google

Refresh the link with:

skills/google-webmcp/scripts/ensure-links.sh

Guardrails

• Keep the Google profile isolated from other sites.
• Google uses bootstrap_then_attach; do not expect Gemini tools to work until the managed profile is authenticated.
• Prefer explicit bridge.session.mode.set over relaunching the command to change runtime mode.
• Long Gemini generations can legitimately take minutes. Increase timeoutMs instead of spawning parallel retries.
• gemini.image.download works on visible generated images in the current or target conversation. Do not assume it can recover images that are no longer visible.
• page.navigate must stay on Google-owned hosts only.
• If the user closes the visible Google window manually, the headed owner session ends. Run google-webmcp-cli bridge.open again if you still need a visible session on the same profile.
