feat: Remove 9 low-value tools and consolidate n8n_health_check (v2.25.0)
Telemetry-driven tool cleanup to improve API clarity: **Removed Tools (9):** - list_nodes - Use search_nodes instead - list_ai_tools - Use search_nodes with isAITool filter - list_tasks - Low usage (0.02%) - get_database_statistics - Use n8n_health_check - list_templates - Use search_templates or get_templates_for_task - get_node_as_tool_info - Documented in get_node - validate_workflow_connections - Use validate_workflow - validate_workflow_expressions - Use validate_workflow - n8n_list_available_tools - Use n8n_health_check - n8n_diagnostic - Merged into n8n_health_check **Consolidated Tool:** - n8n_health_check now supports mode='diagnostic' for detailed troubleshooting **Tool Count:** - Before: 38 tools - After: 31 tools (18% reduction) Concieved by Romuald Członkowski - www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
