Your favorite agent.
Your custom number.

Add NYMobile to ChatGPT

1. Open ChatGPT on the web and go to Plugins.
2. Select +, then Add custom MCP server.
3. Name it NYMobile.si. Under Connection, paste https://nymobile.si/mcp as the Server URL.
4. Choose No authentication. There is no API key, client ID, or OAuth sign-in to complete.
5. Review ChatGPT’s connection notice and select Create as a plugin. Install the resulting plugin if prompted.
6. Start a conversation, type @, and select NYMobile.si. Try one of the prompts below.

Menus can vary. If your account shows Apps or Connectors instead of Plugins, use its custom MCP connection flow. Some accounts require developer mode or workspace administrator approval. If the option is missing, check your platform permissions or use the NYMobile.si.

Add NYMobile to Claude

1. Open Claude and go to Customize → Connectors.
2. Select + Add → Add custom connector.
3. Name it NYMobile.si and paste https://nymobile.si/mcp as the remote MCP server URL. Select Continue.
4. Choose No sign in for authentication. Leave request headers and OAuth credentials empty.
5. Finish with Add. In a conversation, use + → Connectors to enable NYMobile if needed.
6. Ask Claude to use NYMobile and describe the number you want.

On Team or Enterprise, an authorized owner first adds the connector in Organization settings → Connectors → Add → Custom → Web. Members can then enable it. Menu labels and availability can vary by account.

Use another MCP-compatible agent

Look for Add MCP server, Custom connector, or Integrations in your agent’s settings. It must support a remote Streamable HTTP server.
