When you configure an OAuth application in a third-party service (for example, Asana, HubSpot, or Zoom), the service asks for a Redirect URL — the endpoint where it sends users after they authorize the application. For Agen for Work connectors, this URL points to your Frontegg MCP gateway.
Your Redirect URL is built from your MCP Gateway URL and a fixed path:
https://YOUR_MCP_GATEWAY_URL/integration-callback- Open the Settings page in the Agen for Work portal (gear icon in the left sidebar).
- In the Basic configuration panel, copy the value from the MCP Gateway URL field.
- Append
/integration-callbackto the copied value.
See Settings for a full description of the Basic configuration panel.
If you have configured a custom domain in Settings, use the custom domain instead of the default MCP Gateway URL:
https://YOUR_CUSTOM_DOMAIN/integration-callbackBoth the default MCP Gateway URL and a configured custom domain resolve to the same callback endpoint, so either form works.
If your MCP Gateway URL is your-tenant.mcp-gw.frontegg.com, your Redirect URL is:
https://your-tenant.mcp-gw.frontegg.com/integration-callbackPaste this value into the Redirect URL (or Callback URL) field when configuring an OAuth application in the third-party service.
