Configuration

Getting API Keys

1. Create a Google Cloud project at Google Cloud Console
2. Activate the Custom Search JSON API for your project via the API dashboard
3. Generate an API key either through the Credentials section or following the Custom Search API guide
4. Obtain a Search Engine ID by setting up a custom search engine in Google's Programmable Search

Environment Variables

Set these before running the server:

export GOOGLE_API_KEY="your-api-key"
export GOOGLE_SEARCH_ENGINE_ID="your-search-engine-id"

Running from Local Repository

To run the server directly from source:

1. Clone the repository

    git clone https://github.com/ayush-rudani/google-search-mcp-server.git
    cd google-search-mcp-server
   

2. Install dependencies

    pnpm install
    # or
    npm install
   

3. Build the project

    pnpm run build
    # or
    npm run build
   

4. Configure Claude Desktop Update your claude_desktop_config.json:

   {
     "mcpServers": {
       "google-search": {
         "command": "/path/to/node", // <--- Important to add the following, run in your terminal `echo "$(which node)"` to get the path
         "args": ["/full/path/to/google-search-mcp/index.js"],
         "env": {
           "GOOGLE_API_KEY": "your-api-key",
           "GOOGLE_SEARCH_ENGINE_ID": "your-search-engine-id"
         }
       }
     }
   }
   

   • Replace /path/to/node with the complete path to your Node.js executable (you can locate this by running the command which node in your terminal)

5. Test the server

    export GOOGLE_API_KEY=your_api_key_here
    export GOOGLE_SEARCH_ENGINE_ID=your_engine_id_here
    node dist/index.js
   

Rate Limits

The server enforces a rate limit of 10 requests per minute by default to prevent exceeding Google's API quotas. You can adjust this in the code if needed.
