Gemini CLI

#Connect over OAuth (recommended)

~/.gemini/settings.json:

{
  "mcpServers": {
    "marketing-os": {
      "httpUrl": "https://marketing-api.keyescode.com/mcp"
    }
  }
}

Note the key is httpUrl, not url — Gemini CLI uses that to select the Streamable HTTP transport. The first tool call opens the browser for consent.

#Connect with an API key

{
  "mcpServers": {
    "marketing-os": {
      "httpUrl": "https://marketing-api.keyescode.com/mcp",
      "headers": { "Authorization": "Bearer mos_xxxxxxxx" }
    }
  }
}

#First prompts

• "Which of my Marketing OS campaigns is losing money, and by how much?"
• "What are my current spend caps?"
