Prerequisites
- Antigravity installed
- A TryPost Cloud account with an active trial or subscription (start a 7-day free trial)
Setup
1
Open the MCP configuration file
From Antigravity, open MCP Servers → Manage → View raw config, then add the TryPost server without an
Authorization header so OAuth can run:2
Sign in through your browser
Restart Antigravity if needed, then trigger a TryPost tool call. Complete the browser OAuth flow (Allow). Personal Access Tokens are not accepted on the MCP endpoint.
3
Verify the connection
Ask Antigravity:
If Antigravity cannot finish OAuth (no browser callback), use the REST API with an API key from Settings → API Keys instead of MCP.
