{
  "mcpServers": {
    "financenews-mcp": {
      "type": "streamableHttp",
      "url": "http://localhost:3000/mcp",
      "timeout": 600
    }
  }
}

3. Start Using

🔑 Finnhub API Configuration

Getting Your Finnhub API Key

To fetch real financial news, you need to configure a Finnhub API key:

1. Finnhub (finnhub.io)
   • Free tier: 60 requests/minute
   • Sign up at: https://finnhub.io/register
   • Get your API key from the dashboard after registration

Configuration Options

You have two ways to configure your Finnhub API key:

Option 1: Environment Variable (Recommended for personal use)

1. Copy the environment template:

cp env-example.txt .env

2. Edit the .env file and add your Finnhub API key:

FINNHUB_API_KEY=your_actual_finnhub_key

Option 2: MCP Headers (Recommended for shared/team use)

Add headers directly to your MCP client configuration. This is useful when you want different API keys for different clients or when you can't modify environment variables.

Claude Desktop Configuration:

{
  "mcpServers": {
    "financenews-mcp": {
      "type": "streamableHttp",
      "url": "http://localhost:3000/mcp",
      "headers": {
        "X-Finnhub-API-Key": "your_actual_finnhub_key"
      }
    }
  }
}

Supported Header Names:

• X-Finnhub-API-Key (recommended)
• X-API-Key
• Authorization: Bearer your_key (standard Bearer token format)

Error Handling

• API Key Missing: If no Finnhub API key is configured, the tool will display clear instructions on how to obtain and configure the API key
• No Results: If Finnhub API doesn't return any results for your query, the tool will suggest alternative search terms
• Network Errors: Any network or API errors will be clearly communicated with helpful troubleshooting information

The tool does not use sample or fake data - it only returns real news from Finnhub or clear error messages.
