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.	5 months ago
Rene Cannao	2888ee3f45	Fix gemini-code-assist recommendations and implement comprehensive anomaly detection tests ... - Fix retry logic to use is_retryable_error function for proper HTTP error handling - Add exception handling to get_json_int function with try-catch around std::stoi - Improve validate_numeric_range to use strtol instead of atoi for better error reporting - Fix Chinese characters in documentation (non-zero -> non-zero) - Replace placeholder tests with actual comprehensive tests for anomaly detection functionality - Create new standalone unit test anomaly_detector_unit-t.cpp with 29 tests covering: * SQL injection pattern detection (12 tests) * Query normalization (8 tests) * Risk scoring calculations (5 tests) * Configuration validation (4 tests) - All tests pass successfully, providing meaningful validation of core anomaly detection logic Thanks to gemini-code-assist for the thorough code review and recommendations.	5 months 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.
