Antigravity

Antigravity is Google’s agentic IDE and supports MCP via a JSON config, similar to other clients.

Config location

Open the command palette and search for MCP: Open Configuration, or edit the config file directly at:

OS	Path
macOS	`~/Library/Application Support/Antigravity/mcp.json`
Windows	`%APPDATA%\Antigravity\mcp.json`
Linux	`~/.config/antigravity/mcp.json`

Config

{
  "mcpServers": {
    "versuno": {
      "command": "npx",
      "args": ["-y", "versuno-mcp"],
      "env": {
        "VERSUNO_API_KEY": "uk_live_xxx"
      }
    }
  }
}

Remote (hosted HTTP)

To use Versuno’s hosted server instead of npx, point Antigravity at the URL with your key as a bearer token:

{
  "mcpServers": {
    "versuno": {
      "url": "https://mcp.versuno.ai/mcp",
      "headers": {
        "Authorization": "Bearer uk_live_xxx"
      }
    }
  }
}

The hosted server provides the read/query tools only — pull_asset and push_asset need local disk access, so use the npx config above for those.

Reloading

Use MCP: Reload Servers from the command palette after saving the config, or restart the IDE.

Using it

In the Antigravity agent chat, reference Versuno directly:

“Load the ‘bug triage skill’ asset from Versuno.”

Antigravity asks for approval on each tool call. Keep this on. See Security.

Troubleshooting

The MCP status panel (accessible from the command palette) shows which servers are connected and any recent errors. See Troubleshooting for common causes.
