Connect Antigravity to Relay

1. Get your connection link

1. Sign in to Relay with Google. It's free during the beta.
2. Open Integrations, click Set up on Antigravity, then Generate connection URL. Copy it straight away: it's shown only once.
3. Below, YOUR-KEY stands for your link. The dashboard shows the same steps with your link already filled in.

2. Add Relay to Antigravity

1. Antigravity app: open Settings → Customizations, and under Installed MCP Servers click Add MCP. Add Relay with this URL:

   https://mcp.relaymemory.app/mcp/YOUR-KEY

   Copy
2. Antigravity IDE or CLI: add Relay to ~/.gemini/config/mcp_config.json (or .agents/mcp_config.json in a project). Antigravity uses serverUrl:

   {
     "mcpServers": {
       "relay": {
         "serverUrl": "https://mcp.relaymemory.app/mcp/YOUR-KEY"
       }
     }
   }

   Copy
3. Open the agent and check that Relay's tools are listed.

3. Test it

Send this in Antigravity. It should answer from your Relay memory:

Pick up my latest plan from Relay.

Make it save on its own

1. In a Antigravity session, send this once:

   In every conversation, store our work in Relay: save new plans, add progress updates as we go, and keep it up to date.

   Copy
2. Antigravity asks permission to use Relay. Choose Allow always, so it saves as you work. Deleting always asks you first.
3. To keep it on in new sessions, add the same sentence to your project's AGENTS.md.

Using Relay in Antigravity every day

• Relay loads in every Antigravity session. There's nothing to switch on.
• Approve Relay's tools when the agent asks; choose to always allow them where it offers.
• Make it automatic: add this line to your project's AGENTS.md, and it checks Relay on its own.

  At the start of a task, check Relay for the latest plan for this project. When you finish, add a progress update to Relay.

  Copy
