| description | 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. |
Google WebMCP
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
- 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
- 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
- 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
- Use search tools for public search results:
google-webmcp-cli search.web '{"query":"playwright browser automation","limit":10}'
google-webmcp-cli page.get
- 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}'
- 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}'
- 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.
