View All TagsYou can now prompt the app building agent to create REST API or PostgreSQL resources directly from the app builder.
Describe the resource that you want to create, and the agent initiates the resource creation process. You'll be asked to provide credentials or more details where applicable.
Retool encrypts all resource credentials and never exposes them to the agent.
Retool now supports the following new AI models for AI resource queries:
Organizations on the Team plan can now use Retool-provided AI models for app building, in addition to the full catalog of supported models. These models, prefixed with Retool, have been tuned by Retool for enhanced performance and speed for app building.
If the organization has not set a preferred resource for AI app building, the app building agent will use a Retool-provided model.
The following Retool-provided models are supported:
Claude Opus 5.5 is now available in Retool through Anthropic for all paid plans and through Amazon Bedrock for Enterprise plans. It can be used in the following ways:
Organizations on the Free plan now use Retool-provided AI models for app building. These models, prefixed with Retool, have been tuned by Retool for enhanced performance and speed for app building. Access to models from other providers is now only available on paid plans.
Builders using these models will notice comparable quality and faster speeds when compared with other models previously available on the Free plan.
The following Retool-provided models are supported:
Retool now supports using external MCPs as resources in the app builder. The app building agent creates function calls to utilize tools from your connected MCP servers, which can be used while building or at app runtime. For example:
Users of the published app can only trigger MCP tools for which they have permission.
This functionality enables you to use MCP servers from other companies or services in your app. Retool also provides an MCP server with which you can manage your organization and build apps.
Retool now supports the following new AI models:
Retool introduced several features to help Enterprise organizations manage AI usage.
Use the new centralized settings page, AI visibility, to view AI credit usage and BYOK AI token usage. Navigate to Settings, and select Retool managed keys or Bring your own key from the dropdown at the top of the page. You can filter AI usage by instance, model, user, and feature.
This page is available on Enterprise plans. Admins can access it, and other users can access it with delegated Manage billing and Manage usage analytics permissions. Available views depend on the user’s permissions.
Enterprise organizations can also use the new Get AI credit usage endpoint to measure the number of credits consumed for each AI resource that uses a Retool-managed key. You can view the number of credits consumed by resource, user, and surface area.
Learn more about credit and token monitoring.
Retool introduced finer controls on branches in the app builder. You can now rename branches from the Change History panel by hovering over a branch name and clicking the icon.
You can also copy the branch name, which enables builders using Source Control to transition between development in the app builder and development locally. Learn more about switching development environments.
Retool made signficant improvements to the efficiency and performance of the app building agent. Builders will notice faster agent responses and lower AI credit consumption, especially on long-running building sessions. These improvements can result in up to 50% fewer credits consumed.
