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.
🚨 Disclaimer 🚨
This is just a heads-up. We haven't seen any bans from GSearch use.
Not affiliated with Google. Uses the same public OAuth client and API as the open-source Gemini CLI.
Google recently banned some OpenClaw users. OpenClaw use cases for oauth providers look abusive to me. GSearch doesn't fit that pattern. Risk still exists.
Requests carry Gemini CLI's User-Agent, ideType, and request shape, so they're probably indistinguishable from the official client on the wire (if u a googler reading this: we good ppl, plz don't hunt us 🙏). If that bothers you, use a throwaway Google account.
Give Claude Code, Codex CLI, Cursor, and other AI tools real-time web search powered by Google Search grounding. Single binary, zero runtime dependencies. Free with any Google account.
curl -fsSL https://raw.githubusercontent.com/daanielcruz/gsearch-mcp/main/install.sh | bash
Or build from source:
git clone https://github.com/daanielcruz/gsearch-mcp && cd gsearch-mcp
make build && ./gsearch-installer
The installer downloads the binary, configures Claude Code, Codex and Cursor automatically (if available).

Answer with [1][2][3] source links
When an AI tool calls google_search, GSearch returns a grounded answer with inline citations:
The current time in Sao Paulo is 08:13 AM.[1][2]
Sao Paulo observes Brasilia Time (BRT), UTC-3.[3]
Sources:
[1] Time in Sao Paulo (https://...)

GSearch uses the same Google Search grounding API as Gemini CLI. Free with any Google account. No API key, no credit card, no billing setup.
Rate limits are generous for normal usage. The server retries automatically with dynamic backoff on rapid bursts.
Three options:
~/.gemini/oauth_creds.json./gsearch-installer opens your browser for Google sign-inGEMINI_API_KEY / GSEARCH_API_KEY env varOAuth modes auto-provision new accounts via the Google Code Assist API (SMS verification may be required on first use). API key mode skips OAuth entirely and hits the Gemini API directly.
The installer configures everything automatically. For manual setup, add to your MCP client config:
{
"mcpServers": {
"gsearch": {
"command": "npx",
"args": ["-y", "@daanielcruz/gsearch-mcp"]
}
}
}
Works with Claude Code (~/.claude.json), Cursor (~/.cursor/mcp.json), and any MCP-compatible tool.
For Codex CLI (~/.codex/config.toml):
[mcp_servers.gsearch]
command = 'npx'
args = ['-y', '@daanielcruz/gsearch-mcp']
Set GSEARCH_PROJECT env var only if auto-detection fails.
