Add Zoya's server URL, https://mcp.zoya.finance/mcp, to Antigravity's MCP config, then sign in with your Zoya account. You'll need an active Zoya Pro subscription to use it. If your assistant says a Zoya tool requires Zoya Pro, see Why does my AI assistant say a Zoya tool requires Zoya Pro?
Adding Zoya
Open Antigravity's MCP config file. In the Antigravity app, click Customizations in the sidebar, then Installed, and use Copy Config File Path in the MCP Servers section. In the Antigravity IDE, click … at the top of the agent side panel, select MCP Servers, click Manage MCP Servers, then View raw config
Add Zoya under
mcpServers:{
"mcpServers": {
"zoya": {
"serverUrl": "https://mcp.zoya.finance/mcp"
}
}
}Save the file. If it already lists other servers, add the
zoyaentry alongside themGo to Customizations, then Installed. Under MCP Servers, click Authenticate next to zoya. If zoya isn't listed yet, click Refresh
On Zoya's sign-in page, choose Zoya app account, sign in with the same login you use in the Zoya app, and click Allow access
Antigravity shows a code in your browser. Copy it, paste it into the Enter authorization code field in Antigravity, and click Submit
Antigravity CLI
The CLI uses the same config file, at ~/.gemini/config/mcp_config.json. After adding Zoya, run /mcp, select zoya, and choose Authenticate. Open the link it shows, sign in with your Zoya app account, then paste the code into the terminal. The CLI keeps its own sign-in, so you may need to authenticate there even if you already did in the app.
Using Zoya
Ask the agent a question that needs Zoya, for example "Check my watchlist and tell me which stocks aren't Compliant." Antigravity asks for your approval before it runs a Zoya tool. Approve it to continue.
Staying signed in
Expect to sign in to Zoya again about once a week. When that happens, click Authenticate next to zoya again.
Troubleshooting
Check that the server URL is exactly
https://mcp.zoya.finance/mcp, including/mcpat the endIf Zoya shows an error, open More actions (⋮) next to zoya and select Restart, then sign in again. This fixes most problems
If the agent answers without using Zoya, ask it to, for example "Use Zoya to check Apple"
