Connecting to Google Antigravity

Google Antigravity supports the Model Context Protocol (MCP) natively, allowing the editor to securely connect to tools and external services defined in your HasMCP dashboard.

​
Setup Instructions

Antigravity manages connections through its built-in MCP Store.

​
1. Access the MCP Configuration

1

Open Agent Panel

Open the Antigravity Editor and locate the Agent Panel in the side panel.
2

Manage Servers

Click the ”…” (three dots) dropdown at the top of the panel and select Manage MCP Servers.

​
2. Configure Custom HasMCP Server

1

Edit Config

In the Manage MCP Servers view, click on View raw config. This will open your mcp_config.json file.
2

Add Server

Add your HasMCP server to the mcpServers object. You can use the @hasmcp/remote-mcp bridge for enhanced security, or a direct URL connection:

​
Option A: Direct URL Connection

This is the simplest way to connect if your server supports token-based URL authentication.
Uses the @hasmcp/remote-mcp bridge to keep your token in environment variables.
  • PROJECT_ID / SERVER_ID: Your unique project or server identifier from the HasMCP dashboard.
  • YOUR_TOKEN / YOUR_TOKEN_VALUE: The secure token generated for your server.

​
3. Save and Verify

Save the mcp_config.json file. The editor will automatically attempt to initialize the connection. Resources and tools from your HasMCP server will now be available to the AI agent for real-time context and action execution.

​
Troubleshooting

Authentication: Ensure your token is valid and the header is correctly prefixed with Bearer. Node.js Required: Since the connection uses npx, ensure Node.js is installed on your system. Manual Refresh: If tools do not appear immediately, try toggling the server off and on within the Manage MCP Servers list.
