feat: Tool Consolidation - Reduce MCP Tools by 38% (v2.26.0) (#439)
* 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> * fix: cleanup stale references and update tests after tool removal - Remove handleListAvailableTools dead code from handlers-n8n-manager.ts - Update error messages to reference n8n_health_check(mode="diagnostic") instead of n8n_diagnostic - Update tool counts in diagnostic messages (14 doc tools, 31 total) - Fix error-handling.test.ts to use valid tools (search_nodes, tools_documentation) - Remove obsolete list-tools.test.ts integration tests - Remove unused ListToolsResponse type from response-types.ts - Update tools.ts QUICK REFERENCE to remove list_nodes references - Update tools-documentation.ts to remove references to removed tools - Update tool-docs files to remove stale relatedTools references - Fix tools.test.ts to not test removed tools (list_nodes, list_ai_tools, etc.) - Fix parameter-validation.test.ts to not test removed tools - Update handlers-n8n-manager.test.ts error message expectations All 399 MCP unit tests now pass.
