Rahim Kanji	0d56918744	Add full-text search (FTS) tools to MCP query server Implement BM25-ranked full-text search capability for MySQL/MariaDB tables using SQLite-based external FTS index. Changes: - Add MySQL_FTS class for managing SQLite FTS indexes - Add FTS tools: fts_index_table, fts_search, fts_reindex, fts_delete_index, fts_list_indexes, fts_rebuild_all - Add thread-safe FTS lifecycle management with fts_lock mutex - Add reset_fts_path() for runtime FTS database path configuration - Add comprehensive FTS test scripts (test_mcp_fts.sh, test_mcp_fts_detailed.sh)	1 month ago
Rene Cannao	a3f0bade4e	feat: Convert NL2SQL to generic LLM bridge - Rename NL2SQL_Converter to LLM_Bridge for generic prompt processing - Update MySQL protocol handler from /* NL2SQL: / to / LLM: / - Remove SQL-specific fields (sql_query, confidence, tables_used) - Add GENAI_OP_LLM operation type to GenAI module - Rename all genai_nl2sql_ variables to genai_llm_* - Update AI_Features_Manager to use LLM_Bridge - Deprecate ai_nl2sql_convert MCP tool with error message - LLM bridge now handles any prompt type via MySQL protocol This enables generic LLM access (summarization, code generation, translation, analysis) while preserving infrastructure for future NL2SQL implementation via Web UI + external agents.	1 month ago
Rene Cannao	3f44229e28	feat: Add MCP AI Tool Handler for NL2SQL with test script Phase 5: MCP Tool Implementation for NL2SQL This commit implements the AI Tool Handler for the MCP (Model Context Protocol) server, exposing NL2SQL functionality as an MCP tool. New Files: - include/AI_Tool_Handler.h: Header for AI_Tool_Handler class - Provides ai_nl2sql_convert tool via MCP protocol - Wraps NL2SQL_Converter and Anomaly_Detector - Inherits from MCP_Tool_Handler base class - lib/AI_Tool_Handler.cpp: Implementation - Implements ai_nl2sql_convert tool execution - Accepts parameters: natural_language (required), schema, context_tables, max_latency_ms, allow_cache - Returns JSON response with sql_query, confidence, explanation, cached, cache_id - scripts/mcp/test_nl2sql_tools.sh: Test script for NL2SQL MCP tool - Tests ai_nl2sql_convert via JSON-RPC over HTTPS - 10 test cases covering SELECT, WHERE, JOIN, aggregation, etc. - Includes error handling test for empty queries - Supports --verbose, --quiet options Modified Files: - include/MCP_Thread.h: Add AI_Tool_Handler forward declaration and pointer - lib/Makefile: Add AI_Tool_Handler.oo to _OBJ_CXX list - lib/ProxySQL_MCP_Server.cpp: Initialize and register AI tool handler - Creates AI_Tool_Handler with GloAI components - Registers /mcp/ai endpoint - Adds cleanup in destructor MCP Tool Details: - Endpoint: /mcp/ai - Tool: ai_nl2sql_convert - Parameters: - natural_language (string, required): Natural language query - schema (string, optional): Database schema name - context_tables (string, optional): Comma-separated table list - max_latency_ms (integer, optional): Max acceptable latency - allow_cache (boolean, optional): Check semantic cache (default: true) Testing: Run the test script with: ./scripts/mcp/test_nl2sql_tools.sh [--verbose] [--quiet] See scripts/mcp/test_nl2sql_tools.sh --help for usage.

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.

Rene Cannao	40cff23c3b	Initialize MySQL Tool Handler and fix default MySQL port - Initialize MySQL_Tool_Handler in ProxySQL_MCP_Server constructor with MySQL configuration from MCP variables - Use GloVars.get_SSL_pem_mem() to get SSL certificates correctly - Add MySQL_Tool_Handler cleanup in destructor - Change configure_mcp.sh default MySQL port from 3307 to 3306 - Change configure_mcp.sh default password from test123 to empty - Update help text and examples to match new defaults	1 month ago
Rene Cannao	87fff9e046	Add MCP (Model Context Protocol) module skeleton Add new MCP module supporting multiple MCP server endpoints over HTTPS with JSON-RPC 2.0 protocol skeleton. Each endpoint (/mcp/config, /mcp/observe, /mcp/query, /mcp/admin, /mcp/cache) is a distinct MCP server with its own authentication configuration. Features: - HTTPS server using existing ProxySQL TLS certificates - JSON-RPC 2.0 skeleton implementation (actual protocol TBD) - 5 MCP endpoints with per-endpoint auth configuration - LOAD/SAVE MCP VARIABLES admin commands - Configuration file support (mcp_variables section) Implementation follows GenAI module pattern: - MCP_Threads_Handler: Main module handler with variable management - ProxySQL_MCP_Server: HTTPS server wrapper using libhttpserver - MCP_JSONRPC_Resource: Base endpoint class with JSON-RPC skeleton	1 month ago
