Connect Antigravity

Use OpenPost's local MCP bridge with Antigravity. This works with Hosted or a self-hosted instance that your computer can reach, and avoids differences in remote authentication between Antigravity surfaces.

Install and authenticate

Follow the local bridge setup to install openpost-mcp and sign in with the local profile. Use your Hosted or self-hosted origin during login.

Add the MCP configuration

Open Antigravity's MCP configuration through Settings → Customizations → Open MCP Config, or MCP Servers → Manage → View raw config in the IDE. Merge:

{
  "mcpServers": {
    "openpost": {
      "command": "openpost-mcp",
      "args": ["--profile", "local"]
    }
  }
}

Use the full path from command -v openpost-mcp if Antigravity cannot find the command. Save and refresh the MCP servers or restart the app.

Check the connection

Ask, “List my OpenPost workspaces,” then name one and request its schedule without making changes. If authentication fails, sign in again with the same profile. The bridge must run as the user who saved those credentials.

See Google's Antigravity setup guide for the MCP configuration controls.
