Hi IV Glory, When encountering issues with tool nodes not executing in workflows but working in the assistant, consider the following steps to troubleshoot: 1. **Ensure Proper Configuration**: Check if the tool node is properly configured in the workflow. Verify the settings in comparison to when it's functioning in the assistant. 2. **Node Connection**: Confirm that nodes are correctly connected and that no dangling nodes are present, as workflows require fully connected nodes to save and function properly. 3. **Workflow Logs**: Review any logs available for the workflow to identify any errors or messages that might indicate what is going wrong. 4. **Variable Pass-Through**: Make sure that variables collected from conversation nodes are correctly passed and formatted for the tool node. 5. **Tool Node Compatibility**: Verify compatibility of tool nodes with your current workflow setup. Ensure the tool is among those mentioned in the [changelog](https://docs.vapi.ai/changelog/2025/5/17) for MCP (Model Control Protocol) tool calls. 6. **Test and Debug**: Use the built-in debugging features to test the workflow step-by-step, ensuring each node executes as expected. Review these aspects and test your workflow again to see if the issue persists. Adjust configurations as necessary based on what you find during these checks.

Seems like they finally fixed it 🙂
