Gsearch

daanielcruz/gsearch-mcp

Wraps Google Search grounding in an MCP server so Claude and other AI tools can pull live web results with inline citations. Uses the same OAuth flow and public API as the official Gemini CLI, meaning it's free with any Google account and doesn't need API keys or billing setup. Exposes a single google_search tool that returns grounded answers with numbered source links. The Go binary handles auth automatically, either reusing existing Gemini CLI credentials or walking you through browser OAuth. Useful when you want your AI to answer from current web data instead of training cutoff knowledge, though the disclaimer notes Google recently banned some users of similar unofficial tools.
