MCP

Table of contents

Connect Model Context Protocol (MCP) servers to give your agent tools for working with external services. From MCP, choose a predefined server or add a custom server by URL. Authorize access if prompted.

You can also select or connect servers from the tools control in the sandbox launcher. Select a server to use it in the sandbox, and authorize access if prompted. To connect a custom server there, enter its URL and select Connect.

Connecting an MCP server doesn't restrict or inspect the sandbox's other network traffic. To control which hosts and services the sandbox can reach, use network policies. The initial release doesn't support MCP-specific policies.

Connect a predefined server

  1. Open MCP and choose a predefined server.
  2. Connect the server.
  3. Authorize access if prompted.

Add a server by URL

To connect a server that is not predefined:

  1. Open MCP.
  2. Choose the option to add a server and enter its URL.
  3. Connect the server and authorize access if prompted.

Use tools from another client

On the MCP page, use MCP Gateway endpoint URL to connect your external MCP client to the gateway. Select Add to your client, choose your client, and follow the connection and authorization instructions. Supported options include VS Code and Codex CLI. The VS Code instructions include an install link and a manual configuration example.
