AFTER adding the MCP server to your client: 1.Selective tool enabling - Instead of enabling all tools (default), manually select only the specific tools you need for that Workflow's MCP client. 2. Monitor performance - Too many tools can slow down AI responses

💡 Pro Tips

Keep maximum 40 enabled tools - Most AI clients perform better with fewer tools

• Group related operations and only enable one group at a time

• Use the overview note to understand what each operation group does
