Install

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).

How It Works

Claude Code / Codex CLI / Cursor / Others...
        | MCP (stdio)
   gsearch-server (Go binary)
        | OAuth2
   Google Code Assist API
        | googleSearch grounding
   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://...)

Pricing & Limits

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.

Authentication

First run requires a Google sign-in. Two options:

1. Gemini CLI (if installed) -GSearch reuses existing credentials from ~/.gemini/oauth_creds.json
2. Interactive installer -./gsearch-installer opens your browser for Google OAuth

New accounts are auto-provisioned via the Google Code Assist API (SMS verification may be required on first use).

Configuration

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.
