Use external MCPs in app builder
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.
Users of the published app can only trigger MCP tools for which they have permission.
note
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.
