Installation

Prerequisites

• Node.js 18 or higher
• npm or yarn
• Tomba API account (Sign up here)

Option 1: Install via NPX (Recommended)

The easiest way to use the Tomba MCP server is via npx, which doesn't require cloning the repository:

macOS/Linux

Add to your claude_desktop_config.json (~/Library/Application Support/Claude/claude_desktop_config.json):

{
    "mcpServers": {
        "tomba": {
            "command": "npx",
            "args": ["-y", "tomba-mcp-server"],
            "env": {
                "TOMBA_API_KEY": "your-api-key-here",
                "TOMBA_SECRET_KEY": "your-secret-key-here"
            }
        }
    }
}

Windows

Add to your claude_desktop_config.json (%APPDATA%\Claude\claude_desktop_config.json):

{
    "mcpServers": {
        "tomba": {
            "command": "npx",
            "args": ["-y", "tomba-mcp-server"],
            "env": {
                "TOMBA_API_KEY": "your-api-key-here",
                "TOMBA_SECRET_KEY": "your-secret-key-here"
            }
        }
    }
}

Note: The -y flag automatically accepts the installation prompt, and npx will always fetch the latest version.

Option 2: Install from Source

If you want to modify the server or contribute to development:

# Clone the repository
git clone https://github.com/tomba-io/tomba-mcp-server.git
cd tomba-mcp-server

# Install dependencies
yarn install

# Build the project
yarn build

Configuration

Claude Desktop Setup

To use this server with Claude Desktop, add the configuration to your claude_desktop_config.json file.

Using NPX (Recommended)

This method automatically uses the latest published version:

macOS/Linux (~/Library/Application Support/Claude/claude_desktop_config.json):

{
    "mcpServers": {
        "tomba": {
            "command": "npx",
            "args": ["-y", "tomba-mcp-server"],
            "env": {
                "TOMBA_API_KEY": "your-api-key-here",
                "TOMBA_SECRET_KEY": "your-secret-key-here"
            }
        }
    }
}

Windows (%APPDATA%\Claude\claude_desktop_config.json):

{
    "mcpServers": {
        "tomba": {
            "command": "npx",
            "args": ["-y", "tomba-mcp-server"],
            "env": {
                "TOMBA_API_KEY": "your-api-key-here",
                "TOMBA_SECRET_KEY": "your-secret-key-here"
            }
        }
    }
}

Using Local Installation

If you've built from source, use the absolute path to your installation:

macOS/Linux:

{
    "mcpServers": {
        "tomba": {
            "command": "node",
            "args": ["/ABSOLUTE/PATH/TO/tomba-mcp-server/server/index.js"],
            "env": {
                "TOMBA_API_KEY": "your-api-key-here",
                "TOMBA_SECRET_KEY": "your-secret-key-here"
            }
        }
    }
}

Windows:

{
    "mcpServers": {
        "tomba": {
            "command": "node",
            "args": [
                "C:\\ABSOLUTE\\PATH\\TO\\tomba-mcp-server\\server\\index.js"
            ],
            "env": {
                "TOMBA_API_KEY": "your-api-key-here",
                "TOMBA_SECRET_KEY": "your-secret-key-here"
            }
        }
    }
}

Important Notes:

• Replace your-api-key-here and your-secret-key-here with your actual Tomba API credentials
• For local installation, replace /ABSOLUTE/PATH/TO/tomba-mcp-server with the full path to your installation directory
• Restart Claude Desktop after updating the configuration

Getting Tomba API Credentials

1. Visit https://tomba.io
2. Sign up for an account or log in
3. Navigate to your dashboard
4. Go to API settings
5. Copy your API Key and Secret Key

Alternative: Using HTTP Transport

For HTTP transport with npx:

{
    "mcpServers": {
        "tomba": {
            "command": "npx",
            "args": [
                "-y",
                "tomba-mcp-server",
                "--transport",
                "http",
                "--port",
                "3000"
            ],
            "env": {
                "TOMBA_API_KEY": "your-api-key-here",
                "TOMBA_SECRET_KEY": "your-secret-key-here"
            }
        }
    }
}

For HTTP transport with local installation:

{
    "mcpServers": {
        "tomba": {
            "command": "node",
            "args": [
                "/ABSOLUTE/PATH/TO/tomba-mcp-server/server/index.js",
                "--transport",
                "http",
                "--port",
                "3000"
            ],
            "env": {
                "TOMBA_API_KEY": "your-api-key-here",
                "TOMBA_SECRET_KEY": "your-secret-key-here"
            }
        }
    }
}

Usage

Command-line Options

Usage: tomba-mcp-server [options]

Options:
  --transport <type>    Transport type: 'stdio' or 'http' (default: stdio)
  --port <number>       Port number for HTTP transport (default: 3000)
  --help                Show help message

Environment Variables:
  TOMBA_API_KEY         Your Tomba API key (required)
  TOMBA_SECRET_KEY      Your Tomba secret key (required)

Examples:
  # Run with stdio transport (default)

  # Run with HTTP transport on default port (3000)
  node server/index.js --transport http

  # Run with HTTP transport on custom port
  node server/index.js --transport http --port 8080

Standalone HTTP Server

You can also run the server as a standalone HTTP service:

export TOMBA_API_KEY="your-api-key"
export TOMBA_SECRET_KEY="your-secret-key"
node server/index.js --transport http --port 3000

HTTP API Endpoints

• POST /mcp - Send JSON-RPC requests
• GET /mcp - Server-Sent Events for notifications (requires X-Session-Id header)
• DELETE /mcp - Terminate a session (requires X-Session-Id header)
• GET /health - Health check endpoint
• GET /sessions - List active sessions (requires authentication)

Example HTTP Request

curl -X POST http://localhost:3000/mcp \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/call",
    "params": {
      "name": "email_finder",
      "arguments": {
        "domain": "stripe.com",
        "firstName": "Patrick",

X-RateLimit-Remaining: 999
X-RateLimit-Reset: 1609459200

Learn more about Tomba API Rate Limits.

Handling Rate Limits

When you exceed your rate limit, the API returns a 429 Too Many Requests status with:

{
    "error": {
        "type": "rate_limit",
        "message": "Rate limit exceeded. Please try again in 60 seconds",
        "code": 429
    }
}

Best Practices

1. Monitor Usage: Check your dashboard at tomba.io/dashboard
2. Implement Backoff: Handle 429 responses with exponential backoff
3. Batch Operations: Use domain search for multiple emails from the same domain
4. Cache Results: Store results locally to avoid duplicate requests
5. Plan Accordingly: Upgrade your plan based on usage patterns

Usage Tips

• Domain search returns multiple emails per request (more efficient than individual lookups)
• Email verification consumes credits only for valid email formats
• Phone finder may return multiple numbers per request
• Enrichment provides comprehensive data in a single request

Troubleshooting

Server Not Starting in Claude Desktop

1. Check Node.js version: Ensure you have Node.js 18 or higher

   node --version

2. Using NPX:

   • Ensure you have a stable internet connection for the first run
   • The -y flag should auto-accept the installation
   • NPX will cache the package after first use

3. Using Local Installation:

   • Verify absolute path is correct in your config
   • Ensure server/index.js exists: ls -la server/index.js
   • Make sure you ran yarn build successfully

4. Verify API credentials: Ensure your Tomba API keys are correct

5. Check Claude logs:

   • macOS: ~/Library/Logs/Claude/mcp*.log
   • Windows: %APPDATA%\Claude\logs\mcp*.log

NPX-Specific Issues

"npx command not found":

• Ensure npm is installed: npm --version
• NPX comes with npm 5.2.0+, update if needed: npm install -g npm

Package not found:

• Verify the package is published: npm view tomba-mcp-server
• Try clearing npm cache: npm cache clean --force

Always downloading package:

• This is normal behavior with -y flag
• NPX caches the package after first download
• For a permanent installation, use local installation method

Authentication Errors

• Verify your API keys at https://app.tomba.io/dashboard
• Ensure environment variables are properly set in the config
• Check that your API subscription is active

Tools Not Responding

• Check your Tomba API rate limits
• Verify network connectivity
• Review server logs for error messages
