The main agent dropdown menu not appear in 2.14.0 windows

[molavec]

Hi

In the blog, introduce the use of custom agents, but after I tried configuring a custom agent for my project, I didn’t see either GUI the main agent dropdown menu or the antigravity CLI.

Versions:
OS: Windows 11
GUI: 2.14.0
CLI: 1.2.6

Any help to active this feature or fix the mainAgent?

here is the cli image

I can make that appear as a dropdown in GUI chat and CLI, removing de mcpServers.

I tried to keep one of them like an array, but the problem persists.

@molavec

mcpServers:
  - meta-ads-queonda
  - workspices

The custom agent is still not recogniced as a command in chat.

Hi @molavec,

Could you please try these steps:

• Fix the mcpServers field in .agents/agents/meta-ads.md:

  • If meta-ads-queonda and workspices are already configured globally in your MCP settings, remove the mcpServers: block from the frontmatter and instead list specific tool names under tools: (or omit tools: to inherit all available tools):

  • Alternatively, if defining dedicated MCP servers inside the agent file, mcpServers must be a list of objects containing name and command:

    mcpServers:
      - name: meta-ads-queonda
        command: <executable>
        args: [...]
    
    

• Open the Agent Manager view (not the Editor Side Panel):

  • Once .agents/agents/meta-ads.md parses cleanly, open the Agent Manager home view in Antigravity 2.14.0—the Main Agent dropdown will automatically appear above the prompt input.
