Prerequisites

Before setting up the server, make sure you have:

Node.js installed on your system
A Gemini API key from Google AI Studio

Step-by-Step Installation

Install dependencies:
```
npm install
```
Build the project:
```
npm run build
```
Set up your environment variables by creating a .env file in the project root:
```

```

Usage

Integration with Claude Desktop

To use this MCP server with Claude Desktop:

Edit the Claude Desktop configuration file:

On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "gemini": {
      "command": "node",
      "args": ["path/to/gemini-search-server/build/index.js"],
      "env": {
        "GEMINI_API_KEY": "your_api_key_here"
      }
    }
  }
}

Replace "path/to/gemini-search-server/build/index.js" with the actual path to your built index.js file
Replace "your_api_key_here" with your actual Gemini API key

Debugging

Since MCP servers communicate via stdio, you can use MCP Inspector for debugging:

npm run inspector

This will provide a URL to access debugging tools in your browser, making it easier to troubleshoot any issues.

Development Mode

For automatic rebuilds during development:

npm run watch

This will continuously watch for changes in your source files and rebuild the project automatically.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "gemini" '{"command":"node","args":["path/to/gemini-search-server/build/index.js"],"env":{"GEMINI_API_KEY":"your_api_key_here"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "gemini": {
            "command": "node",
            "args": [
                "path/to/gemini-search-server/build/index.js"
            ],
            "env": {
                "GEMINI_API_KEY": "your_api_key_here"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "gemini": {
            "command": "node",
            "args": [
                "path/to/gemini-search-server/build/index.js"
            ],
            "env": {
                "GEMINI_API_KEY": "your_api_key_here"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
