Antigravity connects to the Keupera MCP server over HTTP. Authorize with OAuth (browser sign-in) or an API key.

​
Add the server

1

Open MCP settings

Open the Agent panel → MCP servers → Add server — or edit the MCP config directly:
2

Authorize

Connect keupera and sign in to Keupera in the browser when prompted. To use an API key instead, add "headers": { "Authorization": "Bearer sk_live_your_key" }.
Get your key from Settings → API Keys in the dashboard.

​
Verify and use

Confirm keupera is connected in the MCP servers panel, then ask, for example: “List my tracked keywords by opportunity and draft an article for the top one.”

​
Troubleshooting

Confirm the config uses serverUrl with the exact URL https://mcp.keupera.com/mcp. Reopen the MCP servers panel to reconnect.
For OAuth, reconnect and sign in again. For an API key, confirm the sk_live_… value and that your plan includes API access.
