Google Antigravity release notes: CLI 1.1.23–1.1.24 improves the MCP panel

Google Antigravity CLI 1.1.24, published September 2, makes the /mcp panel easier to control from the keyboard. MCP (Model Context Protocol) is an open standard that connects AI applications to external systems, tools, and data sources. In Antigravity CLI, the panel covers connected MCP servers and plugins.

Google Antigravity release notes: clearer MCP panel and configuration

Version 1.1.24 gives each key a fixed job in the /mcp panel:

  • Up and down arrows move between MCP servers and plugins.
  • Left and right arrows cycle through available actions.
  • Esc leaves action mode or closes the panel.

The same release fixes parsing of mcp_config.json. The file can now contain // or /* */ comments and trailing commas.

Human step

Start an Antigravity CLI session and enter /mcp. Use the up and down arrows to select a server or plugin, left and right to select an action, and Esc to go back.

Antigravity CLI 1.1.23 shows better MCP approvals

Version 1.1.23, published September 1, fixes permission prompts for direct and MCP tool calls. The prompt now shows the tool's declared, human-readable action description instead of a generic title.

The release also fixes subagents configured with enable_mcp_tools=true, which could previously fail with unknown-tool errors. On Windows, MCP configuration files can now be parsed when the JSON file starts with a UTF-8 BOM.

Short example: use the new Antigravity feature

Open /mcp first and confirm that the intended server is connected. Then give the agent this instruction:

Review the MCP tools available in this session. Choose one read-only status or list call that fits the connected server, explain what it will read and what result I should expect, and wait for my approval before calling the tool.

A good result should:

  • Name the server, tool, and information to be read.
  • Stay within one read-only status or list call.
  • Show the tool's human-readable action description in the permission prompt when the call requires approval.
