▽ Add DC Hub to Antigravity

Live data-center, power, grid and fiber intelligence, cited and machine-readable, inside Antigravity. It is one paste — the URL below is the whole install.

Paste this as your Antigravity MCP server URL
https://dchub.cloud/mcp?via=antigravity

An email is optional: it ties the key to you, so we can re-send it if you lose it, and we email a weekly summary of what your key looked up (only in weeks it is used; unsubscribe anytime).
Or copy the URL as it is: it works with no account, at the free daily limit.
Why bother: A key raises your daily limit and gives you a consistent identity across sessions, so DC Hub can tell you what changed in the markets you have been watching instead of meeting you fresh each time.

Where it goes in Antigravity

~/.gemini/antigravity/mcp_config.json

  1. In the agent side panel open … → MCP Servers → Manage MCP Servers → View raw config, or edit ~/.gemini/antigravity/mcp_config.json directly (%USERPROFILE%\.gemini\antigravity\mcp_config.json on Windows).
  2. Add the block below. A workspace-local .agents/mcp_config.json is read too, if you want DC Hub on one project rather than everywhere.
  3. Refresh the MCP server list. DC Hub appears in the agent’s tools.

Config-file route

~/.gemini/antigravity/mcp_config.json

{
  "mcpServers": {
    "dchub": {
      "serverUrl": "https://dchub.cloud/mcp?via=antigravity"
    }
  }
}
Worth knowing. Antigravity spells the field serverUrl and does not accept url or httpUrl — a block copied from Gemini CLI or Cursor is valid JSON and registers nothing at all. Windsurf spells it the same way for the same reason. Antigravity and Gemini CLI are separate clients with separate config files: installing one does not install the other, though both live under ~/.gemini/.
Another client?
