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)	3 months ago
Rene Cannao	06aa6d6ef7	Add comprehensive Doxygen documentation for connection pool Added missing documentation for MySQL connection pool implementation: Header (MySQL_Tool_Handler.h): - Added MySQLConnection struct documentation with member descriptions - Added member variable documentation using ///< Doxygen style Implementation (MySQL_Tool_Handler.cpp): - Added Doxygen blocks for close() method - Added Doxygen blocks for init_connection_pool() with detailed behavior - Added Doxygen blocks for get_connection() with thread-safety notes - Added Doxygen blocks for return_connection() with reuse behavior - Added Doxygen blocks for execute_query() with JSON format documentation All new connection pool methods now have complete @brief, @param, and @return documentation following Doxygen conventions.	3 months ago
Rene Cannao	4eab519848	Implement MySQL connection pool for MySQL_Tool_Handler Added built-in connection pool to MySQL_Tool_Handler for direct MySQL connections to backend servers. Changes: - Added MySQLConnection struct with MYSQL* pointer, host, port, in_use flag - Added connection_pool vector, pool_lock mutex, pool_size counter - Implemented init_connection_pool() to create MYSQL connections using mysql_init/mysql_real_connect - Implemented get_connection() and return_connection() with thread-safe locking - Implemented execute_query() helper method for executing SQL and returning JSON results - Updated tool methods to use actual MySQL connections: - list_schemas: Query information_schema.schemata - list_tables: Query information_schema.tables with metadata - describe_table: Query columns, primary keys, indexes - sample_rows: Execute SELECT with LIMIT - sample_distinct: Execute SELECT DISTINCT with GROUP BY - run_sql_readonly: Execute validated SELECT queries - explain_sql: Execute EXPLAIN queries - Fixed MYSQL forward declaration (use typedef struct st_mysql MYSQL) The connection pool creates one connection per configured host:port pair with 5-second timeouts for connect/read/write operations.	3 months ago
Rene Cannao	221ff23991	Add MySQL exploration MCP tools with SQLite catalog Implemented MCP (Model Context Protocol) server providing tools for LLM-based MySQL database exploration: - MySQL_Catalog: SQLite-based catalog for LLM external memory with upsert, get, search, list, merge, delete operations and FTS support - MySQL_Tool_Handler: 17+ database exploration tools with guardrails: * Inventory: list_schemas, list_tables * Structure: describe_table, get_constraints, describe_view * Profiling: table_profile, column_profile * Sampling: sample_rows (max 20), sample_distinct (max 50) * Query: run_sql_readonly (max 200 rows, 2s timeout, SELECT-only) * Relationship: suggest_joins, find_reference_candidates * Catalog: catalog_upsert, catalog_get, catalog_search, catalog_list, catalog_merge, catalog_delete - MCP Module Integration: * Added 6 new configuration variables for MySQL tool handler (mysql_hosts, mysql_ports, mysql_user, mysql_password, mysql_schema, catalog_path) * Added MySQL_Tool_Handler pointer to MCP_Threads_Handler * Implemented tool routing in MCP endpoint for tools/list, tools/describe, and tools/call methods - TAP Tests: Updated to expect 14 MCP variables (was 8) Files: - include/MySQL_Catalog.h, lib/MySQL_Catalog.cpp - include/MySQL_Tool_Handler.h, lib/MySQL_Tool_Handler.cpp - include/MCP_Thread.h, lib/MCP_Thread.cpp - include/MCP_Endpoint.h, lib/MCP_Endpoint.cpp - lib/Makefile, test/tap/tests/mcp_module-t.cpp	3 months ago
