🚀 Quick Start

Prerequisites

• Node.js 18+

• Claude Desktop application

• TypeScript (for development)

Installation

1. Clone the repository

git clone https://github.com/flyanima/open-search-mcp.git
cd open-search-mcp

2. Install dependencies

npm install

3. Run security checks (recommended)

npm run security:check

4. Build the project

npm run build

5. Configure environment variables (secure method)

# Copy the template and configure your API keys
cp .env.template .env
# Edit .env with your actual API keys (never commit this file)
nano .env

6. Configure Claude Desktop

Copy claude_desktop_config.template.json and update with your paths:

{
  "mcpServers": {
    "open-search-mcp": {
      "command": "node",
      "args": ["path/to/open-search-mcp/dist/index.js"],
      "env": {
        "NODE_ENV": "production",
        "FILTER_TO_README_33": "true",
        "GITHUB_TOKEN": "your_github_token_optional",
        "ALPHA_VANTAGE_API_KEY": "your_alpha_vantage_key_optional"
      }
    }
  }
}

5. Restart Claude Desktop

The 33 tools will be available in your Claude Desktop interface.

Configuration Locations

🔧 API Keys & Security Configuration

🔒 Secure API Key Management

IMPORTANT: Never hardcode API keys in your configuration. Use environment variables for security.

Required for Financial Tools

• Alpha Vantage: Free tier available at alphavantage.co

Optional for Enhanced Features

• GitHub Token: For higher rate limits

• Google Custom Search: For backup search functionality

🛡️ Secure Configuration Methods

Method 1: Environment Variables (Recommended)

# Set environment variables
export ALPHA_VANTAGE_API_KEY="your_key_here"
export GITHUB_TOKEN="your_token_here"

# Then use in Claude Desktop config without exposing keys
{
  "mcpServers": {
    "open-search-mcp": {
      "command": "node",
      "args": ["path/to/dist/expanded-server.js"]
    }
  }
}

Method 2: .env File (Local Development)

# Create .env file (automatically ignored by git)
echo "ALPHA_VANTAGE_API_KEY=your_key_here" >> .env
echo "GITHUB_TOKEN=your_token_here" >> .env

Method 3: Claude Desktop Environment (Less Secure)

{
  "mcpServers": {
    "open-search-mcp": {
      "command": "node",
      "args": ["path/to/dist/expanded-server.js"],
      "env": {
        "ALPHA_VANTAGE_API_KEY": "your_key_here",
        "GITHUB_TOKEN": "your_token_here"
      }
    }
  }
}
