Enhanced Custom Tool Scripts for NetSuite 2026.1

Starting in NetSuite, significant enhancements have been made to custom tool scripts, primarily focusing on increased monitoring and management capabilities. This update introduces a new centralized Custom Tools page and updates to the SuiteCloud Development Framework (SDF) object that improve the visibility and accessibility of script execution logs.

What Are Custom Tool Scripts?

Custom tool scripts enable the creation of tools in NetSuite that external AI clients can invoke via the NetSuite AI Connector Service. These scripts can execute various operations, from retrieving data to initiating actions based on user prompts, enhancing the interaction between AI applications and NetSuite.

Key Enhancements

Custom Tool Script and SDF Object Updates

NetSuite has introduced enhanced functionality for custom tool scripts and the related SDF objects. Key updates include:

• Script Execution Logging: Users can now view logs of custom tool script executions. This can be accessed through Customization > Scripting > Script Execution Logs.
• Required Updates for Implementation:
  • For custom tool scripts:
    • Add the JSDoc tag @NScriptType CustomTool.
    • Ensure entry point functions are declared as asynchronous.
  • For SDF XML files:
    • Rename the object from tool to toolset.
    • Update the scriptid prefix from customtool_ to custtoolset_.
    • Change the attribute exposeto3rdpartyagents to exposetoaiconnector.

These updates enhance monitoring and troubleshooting capabilities by leveraging execution logs for easier debugging and performance assessments.

New Custom Tools Page

A new Custom Tools page provides a streamlined way to view and manage custom tools available within your NetSuite account. This page allows you to explore tools from SuiteApps and account customization projects (ACPs) organized by toolset. Key features include:

• View and manage tools by expanding toolsets to see individual tools and their access permissions.
• Delete ACP toolsets directly from the page, whereas SuiteApp toolsets require navigation to the Installed SuiteApps page for uninstallation.

To access the new Custom Tools page, navigate to Customization > Scripting > Custom Tools.
