The game-changer: You can do this entirely from your phone. Claude lets you connect to remote MCP servers directly from claude.ai on any device. Just open your browser, visit claide.ai, and you're ready to connect. With Claude, you can set it up while grabbing coffee.
Navigate to Settings → Connectors
Open Claude (on web, desktop, or mobile) and go to Settings, then select the Connectors tab. This is where you'll manage all your MCP connections. No technical toggles, just straightforward settings you can access from any device, including your phone.
Click "Add Custom Connector" and paste your MCP endpoint URL
Click the "Add Custom Connector" button and a dialog window will pop up. Name it as you want it to appear and be referred to, then paste your MCP endpoint URL provided with the subscription. Whether you're doing this on your laptop during work hours or on your phone while commuting, the process is identical and takes seconds.
Your connector is ready
Once added, your connector appears in your list with all its available tools displayed. There's nothing else to configure, no restart required, no additional setup. The job is done. You can immediately start using these tools in your conversations with Claude, and they'll work seamlessly across all your devices.
ChatGPT's MCP integration requires the desktop application with developer mode enabled. You'll need access to your computer to set this up as mobile configuration isn't yet supported.
Navigate to Settings → Connectors → Advanced and enable Developer Mode
Open the ChatGPT desktop application and go to Settings, then Connectors, then the Advanced section. Toggle "Developer Mode" on to unlock MCP functionality. This is a desktop-only feature and serves as the gateway to custom connector capabilities.
Click "Create" and configure your connector
Once developer mode is enabled, a "Create" button appears in the top right corner. Click it to open the connector configuration dialog. Name it as you want it to appear and be referred to, then paste your MCP endpoint URL provided with the subscription.
Your connector is ready with all tools available
After configuration, your connector appears in your list showing all available tools. The setup is complete, you can now use these tools directly in your ChatGPT conversations on desktop. No further adjustments needed.
