In just two minutes, you can connect Swallow to ChatGPT and start searching trusted, cited information across thousands of SERFF filings. This quick tutorial walks you through the setup, giving you a faster way to find answers, investigate filings and uncover insights that could otherwise take days of manual research.

Info

ChatGPT plugins and connections to the Swallow SERFF MCP server should work across all ChatGPT account types, including Free accounts. If you’re unable to connect on a Free account, you may need to upgrade your plan. However, as of 20 August 2026, this functionality is available across all account types.

Step 1: Get your Swallow API credentials

Log into SERFF.ai and in your account section you will find both your Client ID and Secret ID.

If you’re new to Swallow, you can register for an account and we’ll provide your credentials during onboarding.

Step 2: Toggle on Developer mode

Click your profile picture and navigate to Settings. Then click on the Plugins menu item and in there click Developer mode.

Toggle Developer mode to ON and then return to Plugins.

Info

Developer Mode is safe to enable when connecting to Swallow. Swallow does not capture, store or retain your ChatGPT conversations or personal data, and any temporary data required to process a request is automatically discarded.

Step 3: Browse Plugins and add a custom plugin

Back in Plugins, scroll down and select Browse Plugins. From here click the Plus icon which will pop up a modal to add a custom plugin.

Step 4: Connect to Swallow's MCP server

ChatGPT will prompt you for connection details and configuration values.

Enter the following as seen below:

SERFF MCP & https://api.serff.ai/mcp - Then check the box and then click Create.

Step 5: Connect your API credentials from earlier

ChatGPT will prompt you to enter your Swallow API credentials , which we discussed in Step 1.

Pasting them in will securely and privately connect ChatGPT to your SERFF.ai Account.

You can find your MCP credentials in Settings → Account Copy the User Keys

Step 6: Start using Swallow with ChatGPT

Once authenticated, you should now have access to SERFF search and filing tools directly within ChatGPT. With the integration active, ChatGPT can securely search, analyse and interact with insurance filings using natural language prompts.

Close the settings modal and begin a new chat to start exploring SERFF filings, rate changes, competitor activity and rating logic through conversation.

With Swallow connected to ChatGPT, you can turn hours or even days of manual filing research into a simple conversation, with answers grounded in trusted SERFF data and linked back to the source.
