Connect Google Antigravity to Entalpa

Configure Entalpa in Antigravity's dedicated MCP profile with the current serverUrl key, then install the skills in the matching user or workspace scope.

before you start

Google Antigravity will ask you to log in

The MCP server serves your own projects, so it authenticates you: the first connection opens a browser and asks for your Entalpa account. Register first, otherwise that prompt has nothing to accept. Registration is free, no card, and MCP calls never spend credits.

Create a free account

requirements

Google Antigravity IDE or CLI installed.
Browser access for OAuth if the client prompts for Entalpa authorization.

install mcp server

Open the dedicated MCP profile

In Antigravity IDE, open the agent panel menu, choose MCP Servers, Manage MCP Servers, then View raw config. Use global ~/.gemini/config/mcp_config.json or workspace .agents/mcp_config.json; Antigravity CLI uses the same paths.

Configure the remote server

{
  "mcpServers": {
    "entalpa": {
      "serverUrl": "https://api.entalpa.com/mcp"
    }
  }
}

Authenticate

Open Agent Settings, Customizations, select Authenticate for entalpa, complete the browser flow, and paste the returned authorization code when prompted.

install entalpa skill

Install from entalpa/entalpa-mcp's default branch for the latest skill, or use a release tag for a reproducible install.

Install the Entalpa skills

npx skills add entalpa/entalpa-mcp --skill "*" --agent antigravity -g -y

verify

Ask Antigravity to list available Entalpa tools or projects.
Confirm the server remains enabled after restarting the IDE or CLI.

known limitations

Remote Antigravity MCP entries require serverUrl; legacy url and httpUrl keys are not supported.
Entalpa OAuth should remain marked runtime-unverified until the authorization-code handoff has been tested in the target Antigravity build.
