Rene Cannao	a816a756d4	feat: Add MCP query tool usage counters to stats schema ... Add stats_mcp_query_tools_counters and stats_mcp_query_tools_counters_reset tables to track MCP query tool usage statistics. - Added get_tool_usage_stats_resultset() method to Query_Tool_Handler - Defined table schemas in ProxySQL_Admin_Tables_Definitions.h - Registered tables in Admin_Bootstrap.cpp - Added pattern matching in ProxySQL_Admin.cpp - Added stats___mcp_query_tools_counters() in ProxySQL_Admin_Stats.cpp - Fixed friend declaration for track_tool_invocation() - Fixed Discovery_Schema.cpp log_llm_search() to use prepare_v2/finalize	4 months ago
Rene Cannao	6f23d5bcd0	feat: Implement two-phase schema discovery architecture ... Phase 1 (Static/Deterministic): - Add Discovery_Schema: SQLite catalog with deterministic and LLM tables - Add Static_Harvester: MySQL INFORMATION_SCHEMA metadata extraction - Harvest schemas, objects, columns, indexes, foreign keys, view definitions - Compute derived hints: is_time, is_id_like, has_pk, has_fks, has_time - Build quick profiles and FTS5 indexes Phase 2 (LLM Agent): - Add 19 new MCP tools for two-phase discovery - discovery.run_static: Trigger ProxySQL's static harvest - Catalog tools: init, search, get_object, list_objects, get_relationships - Agent tools: run_start, run_finish, event_append - LLM tools: summary_upsert, relationship_upsert, domain_upsert, etc. Files: - include/Discovery_Schema.h, lib/Discovery_Schema.cpp - include/Static_Harvester.h, lib/Static_Harvester.cpp - include/Query_Tool_Handler.h, lib/Query_Tool_Handler.cpp (updated) - lib/Makefile (updated) - scripts/mcp/DiscoveryAgent/ClaudeCode_Headless/prompts/ - scripts/mcp/DiscoveryAgent/ClaudeCode_Headless/two_phase_discovery.py	4 months ago
Rene Cannao	c86a048d9c	Implement MCP multi-endpoint architecture with dedicated tool handlers ... This commit implements Option 1 (Multiple Tool Handlers) for the MCP module, where each of the 5 endpoints has its own dedicated tool handler with specific tools. ## Architecture Changes - Created MCP_Tool_Handler base class interface for all tool handlers - Each endpoint now has its own dedicated tool handler: - /mcp/config → Config_Tool_Handler (configuration management) - /mcp/query → Query_Tool_Handler (database exploration) - /mcp/admin → Admin_Tool_Handler (administrative operations) - /mcp/cache → Cache_Tool_Handler (cache management) - /mcp/observe → Observe_Tool_Handler (monitoring & metrics) ## New Files Base Interface: - include/MCP_Tool_Handler.h - Base class for all tool handlers Tool Handlers: - include/Config_Tool_Handler.h, lib/Config_Tool_Handler.cpp - include/Query_Tool_Handler.h, lib/Query_Tool_Handler.cpp - include/Admin_Tool_Handler.h, lib/Admin_Tool_Handler.cpp - include/Cache_Tool_Handler.h, lib/Cache_Tool_Handler.cpp - include/Observe_Tool_Handler.h, lib/Observe_Tool_Handler.cpp Documentation: - doc/MCP/Architecture.md - Comprehensive architecture documentation ## Modified Files - include/MCP_Thread.h, lib/MCP_Thread.cpp - Added 5 tool handler pointers - include/MCP_Endpoint.h, lib/MCP_Endpoint.cpp - Use tool_handler base class - lib/ProxySQL_MCP_Server.cpp - Create and pass handlers to endpoints - lib/Makefile - Added new source files ## Implementation Status - Config_Tool_Handler: Functional (get_config, set_config, list_variables, get_status) - Query_Tool_Handler: Functional (wraps MySQL_Tool_Handler, all 18 tools) - Admin_Tool_Handler: Stub implementations (TODO: implement) - Cache_Tool_Handler: Stub implementations (TODO: implement) - Observe_Tool_Handler: Stub implementations (TODO: implement) See GitHub Issue #8 for detailed TODO list.
