I've successfully deployed a Custom Tool script (Creating Custom Tools for the NetSuite AI Connector Service- MCP SuiteApp) via SDF ACP to a NetSuite 2025.2 sandbox. The deployment completes without errors, the object registers as "_customagenttool_" in NetSuite, the standard MCP tools (Get Record, Run Custom SuiteQL, etc.) all appear in Claude, but the custom tool never shows up in the tool list, even with higher permission role.

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** Based on the conversations, it seems like the issue you're facing with the custom tool not showing up in the tool list in Claude, even after successful deployment and registration as "_customagenttool_" in NetSuite, could be related to permissions. In one of the conversations, it was mentioned that the visibility of tools in Claude might be based on permissions. For example, to use getCustomerDetails, the role needs view permission for Customers. Similarly, to use getItemDetails, view permissions on Item Record are required. However, it's not clear which specific permissions are needed for your custom tool to appear. One user mentioned adding a lot of permissions and then being able to get getItemDetails and checkInventoryLevels. Another point to consider is the creation of a script-record and its deployment after uploading the script file. This was mentioned in the context of turning on the SuiteQL Query Tool. Please review the permissions associated with the role that's trying to access the custom tool in Claude. You might need to add more permissions related to the functionality of your custom tool. Also, ensure that a script-record has been created and deployed for your custom tool. If the issue persists, you might need to review the implementation of your custom tool or consult with other NetSuite professionals who have successfully implemented custom tools.
