Connect Agent Nexus to Gemini CLI

Gemini CLI reads MCP servers from ~/.gemini/settings.json.

  1. 1. Edit settings.json

    Use httpUrl for streamable HTTP servers.

    {
  "mcpServers": {
    "agent-nexus": {
      "httpUrl": "https://agentnexus.app/mcp"
    }
  }
}

  2. 2. Check it

    Run /mcp inside Gemini CLI.

    /mcp

Test it

Ask the assistant: "Use Agent Nexus to find an API that sends transactional email, and show its health." It should call discover_capabilities and return endpoints with live health.
