Antigravity IDE

Connect Antigravity IDE to agentgateway

Configure Antigravity IDE to use agentgateway as an MCP server.

Before you begin

1. Install and run agentgateway.
2. Confirm agentgateway is up by opening the agentgateway UI.
3. Use the same MCP endpoint and port that your local config exposes. Common examples include:
   • http://localhost:15000/mcp/sse
   • http://localhost:15000/mcp/http
   • If you run agentgateway on a different host or port, replace localhost:15000 in the examples accordingly.

Configuration

Add agentgateway to your Antigravity IDE MCP configuration. Set the serverUrl to your agentgateway proxy address, which defaults to http://localhost:15000/mcp/sse for local deployments:

{
  "mcpServers": {
    "agentgateway": {
      "serverUrl": "http://localhost:15000/mcp/sse"
    }
  }
}

Verify the Connection

1. Restart Antigravity IDE by closing the application and reopening it.
2. Check that agentgateway tools are in the MCP tools list (usually found in the MCP or Tools panel).
3. Click a tool, then click Run (or equivalent button). The tool execution verifies the connectivity with agentgateway.
