Installation

Installing via Smithery

To install MarineTraffic Vessel Tracking Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @Cyreslab-AI/marinetraffic-mcp-server --client claude

Prerequisites

• Node.js 18 or higher
• A MarineTraffic API key (available from MarineTraffic API Services)

      "command": "node",
      "args": ["/path/to/marinetraffic-server/build/index.js"],
      "env": {
        "MARINETRAFFIC_API_KEY": "your-api-key-here"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

For Claude VSCode Extension

Edit ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json:

API Key Limitations

The MarineTraffic API has usage limits based on your subscription plan. Be aware of these limits when using the server to avoid exceeding your quota.

Troubleshooting

• API Key Errors: Ensure your MarineTraffic API key is valid and correctly set in the environment variables.
• Rate Limiting: If you encounter rate limiting errors, the server will automatically retry with exponential backoff, but you may need to wait before making additional requests. Example of detailed vessel information available through the API
