Changelog

You can now connect MCP servers (the standard that lets AI assistants use outside tools) to the build chat. The Hercules agent can use their tools and data while building your App, so it can pull in context and take actions in the tools you already use.

• Browse a catalog. Turn on popular connectors with a click.
• Add your own. Connect any MCP server by URL. Sign-in uses OAuth, so most connectors need no API keys.
• Control each tool. Choose which tools the agent can run, and whether it needs your approval first.

Connectors are installed per-user and visible only to you.

To get started, open the Connectors tab in the App Builder and turn on a connector.

You can now pick between four AI models from the chat input. Two new tiers, Expert - Fast and Balanced, join the existing Expert and Lite.

• Expert - Fast. Expert quality with less waiting. It is 2.5x faster than Expert at 2x the cost.
• Expert. The most powerful and most accurate model. Best for planning and complex work.
• Balanced. Strong quality at a balanced cost. A middle ground between Expert and Lite.
• Lite. The cheapest model, but less accurate. Best for low-risk tasks like content updates and translations.

Expert - Fast, Expert, and Balanced are available on Pro, Business, and Ultra plans. Lite is available on all plans.

To get started, click the model name in the chat input to switch. Learn more in the Hercules AI docs.

You can now import a CSV file directly into a table in your App's database.

Upload a spreadsheet from the Database tab, pick the table to fill, and choose how to handle data that is already there:

• Append. Add the new rows to the table's existing data.
• Replace. Overwrite all rows in the table.
• Require empty. Import only when the table has no rows yet.

To get started, open the Database tab in the App Builder and click Import CSV. Learn more in the Database docs.

You can now use Hercules from any AI assistant. The Hercules MCP server connects your account to ChatGPT, Claude, Cursor, and other assistants that support MCP (the standard that lets assistants use outside tools), so you can build Apps without leaving the chat.

Once connected, your assistant can:

• Create Apps. Describe what you want and your assistant builds and publishes it with Hercules.
• Edit Apps. Send changes to an existing App and follow the build.
• Browse your work. List and read your Apps and the chat threads behind them.
• Check your organization. See your plan, remaining credits, and recent Apps.

Sign-in uses OAuth, so there are no API keys to manage. Each connection is scoped to the one organization you pick, and Apps you create from your assistant show up in the App Builder.

To get started, add https://hercules.app/mcp to your assistant and sign in. Learn more in the Hercules MCP docs.

Drop large PDFs and other files into the chat with the Hercules Agent. PDFs over 100 pages now go through without being blocked.

• Updated file UI. Non-image files like PDFs and CSVs show as a chip with an extension badge and filename. Images still display as a square card.
• Warning badges. Uploads that exceed the Agent's size or type limits are marked with a warning. The file still saves to Hercules Files and Media, but the Agent does not see it directly.

To get started, drop any file into the chat window in the App Builder.

We have renamed the Report an Issue sidebar button to Support & feedback.

The Support & Feedback portal opens a small hub where you can

1. Submit and manage support tickets
2. Learn more about Hercules
3. Contact sales or become an affiliate

Supporting our customers no matter their size is a #1 priority for Hercules. We always plan to have humans available to help in case you need it!

You can now manage all of your chat threads in a vertical sidebar.

The new vertical chat sidebar includes the ability to create, search, pin, archive, and delete threads. Threads are automatically grouped by date.

We think this is a far easier way for you to manage multiple chats at a time. We are excited for you to try it out!

To get started, just click the expansion icon in the top left of the chat.
